CONTRACTOR may submit alternative offers for other materials for consideration. In the case of combined Hot and Acoustic Insulation, the same material can be used for both purposes, provided the acoustical requirements of ISO 15665 specification are met. The thickness of the absorbent layer shall be determined by the more stringent of the two requirements.

In the case of Acoustic and combined Hot and Acoustic of 26’’ (and above) piping and equipment operating below 125°C, flexible aerogel insulation blankets from Aspen Aerogels, Inc. (Cryogel Z) shall be used.

In the case of Acoustic and combined Hot and Acoustic of 26’’(and above) piping operating above 125°C, all insulation shall be designed with a or several inner layer(s) of Pyrogel XTE and outer layers of Cryogel Z.

For Cold Acoustic Insulation, the porous layer shall be applied as an addition to the cold insulation. All acoustic insulation for Cryogenic/Cold service shall be encapsulated with an approved vapour barrier.

ACC and ACD insulation system can be designed with a combination of PIR and Mineral wool insulation materials.

The mineral fiber for sound control insulation on pipes shall be in accordance with ASTM C547 and the requirements of Annex C1.

Mineral wool board for valve and flange covers shall conform to ASTM C612, Type IV and the requirements of Annex C1.

Mass Filled Vinyl sheet or Mass Loaded Vinyl shall possess the following properties: density of 5.0 kg/m2 (1.0 lb/ft²) with minimum STC of 26 tested per ASTM E90 and service temperature range of –20°C to 93°C (-4°F to 200°F), Tensile strength of 2,750 kPa, Elongation 200%. MFV sheet must be non-metallic.

Clause 16.6.2 Jacketing – Substitute second paragraph with:

Metal jacketing for acoustic insulation shall follow the corresponding thermal insulation specification; i.e

a) Hot Acoustic Insulation must follow the metal jacketing requirement on the Hot Insulation in Part 1.

b) Cold Acoustic Acoustical insulation must follow the metal jacketing requirement on the Cold Insulation

in Part 2.

Where Aluminum jacketing is used over acoustical insulation, it shall be minimum 0.50 mm (0.020 in) thick for piping and equipment.

Where Stainless Steel jacketing is used, it shall be minimum 0.41mm (0.016 in) thick for piping and equipment. For passive fire protection applications utilizing Cryogel Z or Pyrogel XTF, stainless steel jacketing must be used. Thickness shall be 0.51 mm minimum for pool fire, and 0.81 mm minimum for jet fire.

Non-metallic jacketing with dampening properties may also be considered in non-fire hazard areas.

Clause 16.6.5 Insulation System and Performance Requirements – New clause

The porous layer(s) of sound control insulation shall be pre-formed mineral fiber or open-cell type flexible plastic foam. SUPPLIER shall ensure that his insulation system meets insertion loss requirements shown in Table 26.

When mineral wool is used, the porous layers thicknesses for classes C and D of acoustic insulation systems are shown in the Table C2 of Annex C. Sketches illustrating these typical arrangements of thermal acoustical insulation are shown in the same Annex C.

A similar table (table C3) has been developed by the MANUFACTURER of flexible aerogel blankets for the various acoustic classes combined with hot or cold insulation. A typical sequence of insulation materials for combined thermal and acoustic insulation using Pyrogel XTE (hot insulation) or Cryogel Z (cold insulation) are shown in Figures C4 and C5.

Clause 19.2 Extent of Insulation – Substitute clause with:

The P&ID, isometrics and the Piping Line identifies lines to be insulated for sound control per this specification.

Acoustical piping insulation shall start from the noise source such as the rotating equipment, valve or orifice plate and unless otherwise specified shall be carried over to first equipment but excluding that equipment.

Line valves, flanges and fittings on pipes receiving (AHC, AHD, ACC, ACD, AEC, AED, APC, APD) insulation shall be acoustically insulated.

Acoustical insulation shall cover all pipe supports, trunnions and structural steel members supporting the respective piping. Where installation is not possible, an RFI must be raised for resolution.

GENERAL

Introduction

1.1.1

This Specification defines COMPANY minimum requirements for design, materials, application and quality control of external Thermal (Hot, Cold, Dual) of pipework, vessels and equipment operating between -180°C and 700°C for new & existing facilities located above ground either onshore or on offshore installations. This specification also defines the special requirements of Acoustic insulation for pipes, valves, and flanges with the aim of reducing the noise emitted by these items.

Purpose

Insulation is required to conserve heat of piping and equipment, reduce the transfer of heat to piping and equipment, to control process temperatures (avoid condensation, solidification or excessive viscosity of fluids and materials, minimising heat gain during fire conditions), provide personnel protection and noise control.

Definitions and Abbreviations

The following defined terms are used throughout this specification:

“ACOUSTIC INSULATION” Consists of a sound-absorbing material (the ‘porous layer’) on the pipe and an impermeable outer cover (the ‘jacketing’). It is applied with the aim of reducing the noise radiated from the pipe.

“ADNOC” means Abu Dhabi National Oil Company.

“ADNOC Group” means ADNOC together with each company in which ADNOC, directly or indirectly, controls fifty percent (50%) or more of the share capital.

“Approving Authority” means the decision-making body or employee with the required authority to approve Policies and Procedures or any changes to it.

“Business Support Directorates and Functions” or “Non- BLD” means all the ADNOC functions and the remaining directorates, which are not ADNOC Business Line Directorates.

“CEO” means chief executive officer.

“COMPANY”: ADNOC Group of Companies.

“CONCESSION REQUEST”: A deviation requested by the MANUFACTURER/SUPPLIER, usually after receiving the contract package or purchase order. Often, it refers to an authorization to use, repair, recondition, reclaim, or release materials, components or equipment already in progress or completely manufactured but does not meet or comply with COMPANY requirements. A CONCESSION REQUEST is subject to COMPANY approval.

“CONTRACTOR”: means the party(s) which carries out all or part of the design, engineering, procurement, construction, commissioning, or management of the PROJECT.

“Corrosion Under Insulation” - An acceleration of corrosion due to ingress of moisture into external insulation where the operating temperature is in the range of -5 °C to 175 °C

“Noise Level” may refer to either a sound pressure level (Lp) with reference to 20 µPa, or a sound power level (Lw) with reference to 1 pW.

Where:

Lp = 20 log10 (P/P0)_P0 = 20 µPa

Lw = 10 log10 (W/W0)_W0 = 1 pW

Note: All logarithms in this specification are to the base 10, unless otherwise noted.

“NOISE LIMIT” is a maximum allowable noise level.

“OPERATING TEMPERATURE” - Continuous operating temperature, of the item to be insulated, during normal operating conditions. Temperatures reached during upset conditions and steam-out temperature shall not be considered as the operating temperature. Insulation thickness shall be based on OPERATING TEMPERATURE.

The term “machinery” includes engines, turbines, compressors and pumps etc.

5.1.2

Cold Insulation and Dual Temperature Service

The insulation of cold and dual temperature services is required for:

• Cold conservation (i.e. reduction in heat gain).

• Preventing vapour condensation on the outside surface of the insulating system of piping and

equipment having a temperature below the dew point of the surrounding atmosphere.

• Personnel protection from cold surfaces (cold burns and falling ice).

• An important requirement of a cold insulation system is to prevent water ingress into the insulation.

5.1.2.1 Cold Insulation

Cold service is defined as equipment and piping at operating temperatures below ambient where reduction of heat gain and the prevention of surface condensation or icing on the outside surface is desired within a temperature range of ambient and below.

5.1.2.2 Dual Temperature Service

Dual temperature service is defined as vessels, equipment and piping at operating temperatures below ambient and where intermittently temperatures may occur up to 150°C, or with normal pipe operating temperatures which are above ambient but intermittently reach ambient temperatures for a longer period of time where good causes for occurrence of condensation within the insulation finish exist.

Where required, this insulation prevents surface condensation, conserves low temperatures or controls heat input into the contained fluid within the temperature range of -100 °C up to +150 °C.

8.2.1

The type and extent of insulation requirements shall be as specified on the P&IDs, Piping Line List, equipment drawings, piping isometrics and instrument list.

8.2.2

The required thermal insulation thickness shall be determined by using the insulation thickness charts in this specification. Table 4 identifies typical thicknesses of hot insulation for various ranges of operating temperature; stipulated thicknesses do not include the covering or jacketing, the insulating effect of which is neglected.

8.2.3

For the purposes of selecting the insulation thickness, operating temperature shall be determined as follows unless specified otherwise by COMPANY:

• For non-jacketed piping and equipment, the normal operating temperature of the substrate metal

shall be used.

•

For steam jacketed piping and equipment, the jacket fluid temperature shall be considered as the operating temperature.

• For heat exchangers, the average of the inlet and outlet temperatures the particular side (shell or tube side that is being insulated) shall be considered the operating temperature (O.T) except for personnel protection. For personnel protection, the higher of the inlet and outlet temperatures for the particular side shall be considered.

• For vertical equipment having fluid temperature variations over the equipment length, the operating temperature of the fluid under the relevant insulated section shall be used and the insulation thickness may be varied as required over the equipment length.

8.2.4

Single layer pipe insulation shall be applied in a staggered circumferential joint arrangement. Where multi-layer insulation is required, the following minimum requirements shall be met:

•

supports extended to provide support for each layer;

• each individual layer secured (banded);

•

terminations / joints staggered in a stepped arrangement

8.2.4.1

If insulation is furnished in standard thickness other than indicated in Table 4, the next thicker available standard size of the specified material commercially available shall be applied.

8.2.4.2 The thickness of insulation on vessels may be determined by the requirements for thermal relief. The CONTRACTOR shall confirm to COMPANY by the presentation of calculations that the thicknesses quoted are satisfactory for the particular thermal retention properties desired.

PART 2: COLD INSULATION

GENERAL

COLD INSULATION CLASIFICATION

10.1.1 Cold insulation where required prevents condensation or icing on the outside surface of the insulating system, conserve low temperatures or controls heat input into the contained fluid within a temperature range of ambient and below. An important requirement of a cold insulation system is to prevent water ingress into the insulation. The presence of water as vapour, liquid or ice in the insulation will decrease its insulating value and may eventually lead to under lagging corrosion of the insulated metal surfaces. In order to prevent water ingress and under lagging corrosion, the vapour barriers and metallic jacketing should be properly selected and applied and all insulated metal surfaces shall be suitably painted in accordance to AGES-SP-07-004.

10.1.2 Dual temperature service: It is defined as vessels, equipment, and piping at operating temperatures below ambient and where intermittently temperatures may occur up to 150°C, or with normal pipe operating temperatures which are above ambient but intermittently reach ambient temperatures for a longer period of time where good causes for occurrence of condensation within the insulation finish exist. Where required, this insulation prevents surface condensation, conserves low temperatures or controls heat input into the contained fluid within the temperature range of -100 °C up to +150 °C.

Insulation system

10.2.1 For cold and dual-temperature services in the temperature range from below ambient up to 90 °C, both Polyurethane Foam / Polyisocyanurate Foam (PUF/PIR) or cellular glass can be used. Above 90 °C, only cellular glass shall be used. The insulation system for cold and dual-temperature services can be applied either completely with layers of rigid pre-formed sections (PUF/PIR and/or cellular glass) or a combination of pre-formed sections with dispensed PUF.

10.2.1.1 Where the use of pre-formed polyisocyanurate foam sections is impractical and with the prior agreement of COMPANY, sprayed or foamed in situ materials may be considered. Samples shall be taken during application for quality control purposes.

10.2.1.2 The insulation system for cold and dual-temperature services can be applied either completely with layers of rigid pre-formed sections (PUF/PIR and/or cellular glass) or a combination of pre-formed sections and a layer of dispensed PUF.

10.2.1.3 A secondary vapor barrier shall be applied between the outermost layer and the next inner layer of the insulation, except in the case when only cellular glass is used. The insulation shall then be finished with a primary vapor barrier on the outside and surrounded with a metallic jacket. The various types of insulation systems are shown in Appendix 41 - details for insulation systems.

10.2.1.4 The insulation contractor may propose alternative insulation systems, provided the materials used meet the requirements of this specification and that the systems have demonstrated thermal and structural integrity after “cryogenic condition” testing of 10 thermal cycles. The test pipe for cryogenic condition testing shall have a minimum diameter of NPS 10 and a minimum length of 4.0 m. Insulation system is acceptable if no icing or structural damage occurs during testing.

PART 3: ACOUSTIC INSULATION

GENERAL REQUIREMENTS

The purpose of this document is to define the specials requirements of acoustical insulation for pipes, valves, and flanges with the aim of reducing the noise emitted by these items.

In many respects, acoustic insulation resembles thermal insulation and is frequently installed by a subcontractor specializing in thermal insulation. However, some aspects of acoustic insulation are different. The differences between acoustic and thermal insulation are discussed to provide guidance to both the Noise Control Engineer and the insulation SUBCONTRACTOR. Aspects of acoustic insulation that are in common with thermal insulation are the compatibility with the environment of materials for porous layer and cladding, fastening, sealing, surface protection and safety regulations

The overall noise control design, implementation, and compliance are the responsibility of the CONTRACTOR(S) for the area(s) of the project in their scope. The CONTRACTOR shall use the project noise specifications to develop plant and individual equipment noise limits. Further, the CONTRACTOR shall develop the noise control plan for all non-equipment noise services, including general piping. The provisions for the acoustical treatment of pipes, valves, and flanges shall be per this specification.

When acoustic attenuation is combined with thermal insulation, the thickness of the insulation layer shall be determined by the more stringent of the two requirements.

LIMITATIONS AND EXCLUSIONS OF ACOUSTIC INSULATION

Although this specification does not specifically cover the acoustic insulation of other equipment such as large vessels and machinery, such treatments should follow the basic principles and guidelines of this document per the direction of the Noise Control Engineer and/or Acoustic Consultant. Note all lagging and insulation treatments on machinery require the approval of the COMPANY, per project noise control specifications.

MATERIALS AND DESIGN

Acoustical Design

ISO 15665 forms an integral part of this Specification and the definitions of which have been used throughout. Also, detailed information on acoustical definitions, calculations, and measurements is given in EEMUA 140. Where conflict arises, the requirements of this Specification shall take preference.

For acoustical design purposes, all calculations should be performed in the eight octave bands cantered between 63 Hz and 8 kHz (refer ISO 266). The overriding requirement for acoustical design is that the A-weighted Noise Level shall be met.

To mitigate the likelihood of acoustic induced fatigue, insulation thickness shall be elected based on certified test results to achieve the specified work area and environmental noise limits for the facility in accordance with ISO 15665.

Acoustic Insulation

Acoustic insulation shall consist of a porous layer and outer jacketing. The porous layer serves to provide vibration isolation of the jacketing from the pipe and converts acoustic and vibration energy into heat. The jacketing acts as a barrier to the noise radiated from the pipe (and shell therefore be completely sealed) and provides weather protection for the porous layer.

ADNOC Classification: Internal

General Characteristics

The noise radiated by the wall of a pipe is usually generated by equipment connected to the pipe, such as compressors, pumps, valves, or ejectors. The noise sources may cause long sections of pipe to radiate noise because noise will travel in the pipe with little reduction. The noise radiation may be reduced by acoustic insulation.

Objectives of Acoustic Insulation

Although materials used for thermal insulation may also be suitable for acoustic insulation, there are some additional application requirements. Special attention shall be paid to the prevention of noise leakage through gaps and to isolation of vibrations in order to prevent their transmission to the cladding or adjacent structures, such as supports.

It is emphasized that the ultimate success of acoustic insulation depends on the quality of installation; small gaps or bridging effects can have a far greater effect on the acoustic properties than on the thermal properties and may completely negate the acoustic performance. A regular inspection during installation is therefore an important aspect.

16.4.1 Noise Requirements

The control of noise in a plant is required for the following reasons:

•

to conserve the hearing of personnel,

to reduce speech and work interference,

to ensure that warning signals are audible,

to allow adequate speech, telephone, and radio communication,

to maintain working efficiency,

to provide quiet accommodation for personnel,

to prevent annoyance to the neighbouring community.

Classes of Acoustic Insulation

Four classes of acoustical insulation are considered; denoted as A, B, C, and D.

The dimensions of the acoustical insulation for the four defined classes shall be as indicated in Table 25 unless otherwise agreed in writing by the COMPANY. With a good quality of installation, the acoustical performance obtained with the various classes will be as given in Table 26

four classes. A requirements of Table 26 strictly define NOTE: The acoustic CONTRACTOR/SUBCONTRACTOR wishing to propose alternative constructions shall state which class he is referring to. He shall also give evidence that the proposed construction has the required acoustic performance.

Note

Where a high mass per unit area is required for the cladding, this may be composed of two layers. An example of an acceptable construction is to combine an outer layer of steel or aluminium and an inner layer of barium oxide/sulphate loaded vinyl film to provide the additional mass.
The performance of an acoustic insulation system is related to the wall thickness of the pipe. The insulation systems of Table 25 are based on standard pipe wall thickness. Thinner pipe walls may adversely affect the performance of the insulation system, but an increase in wall thickness will not influence the performance significantly.
When dual-layer insulation systems employing different insulation materials are used for combined thermal

and noise control, the acoustic insulation shall be installed as the outer layer.

Materials

This section lists materials suitable for acoustical insulation and the particular properties necessary for acoustical purposes. All materials shall comply with hot insulation material (Refer Section 8.1). They shall be suitable for the maximum operating temperatures and for the chemical nature of the environment

The following materials are suitable for acoustical purposes:

a) Mineral wool

b) Glass fiber

c) Resilient closed cell elastomeric insulation.

The porous layer serves the following purposes:

•

It represents a vibration-isolating support for the cladding.

It converts acoustical and vibration energy into heat and should therefore have an optimum flow resistivity for the oscillatory flows which occur in sound waves.

16.6.2

Jacketing

Jacketing serves the following purposes

•

It is a barrier to the noise radiated by the pipe and shall, therefore, be completely sealed.

It protects the porous layer from mechanical damage and provides a weather protection for the porous layer and the pipe surface underneath. It shall, therefore, have sufficient strength and durability for these purposes.

The following materials are suitable for acoustical purposes:

The minimum mass per unit area of the jacketing (for the class of insulation considered) shall be in accordance with Table 25.

16.6.3 Anti-Vibration Seals

The following materials are suitable for use in anti-vibration seals:

a) Synthetic and natural rubber

16.6.4

Jacketing Support

Where the porous layer is composed of semi-rigid sections and the pipe is horizontal, it will not normally be necessary to support the jacketing. However, where blankets are used, it may be necessary to support the jacketing separately. Short, semi-rigid sections, installed at regular intervals, may be found suitable for this, provided they are compatible with the operating temperature and the chemical environment.

Rigid spacers, as used in distance rings for thermal insulation, shall not be used in acoustical insulation. Spacers shall contain resilient elements. The spring stiffness, k, in N/m of a single element and in directions normal to the pipe axis, should be of the order:

The resilient elements shall have a built-in mechanical stop, in the direction normal to the pipe axis, in order to limit its maximum deflection.

Support rings (See Appendix 67) which carry the weight of vertical stretches of acoustical insulation shall contain resilient elements. The spring stiffness, k, in the vertical (= axial) direction, in N/m of a single element, should be of the order:

Spring stiffness in lateral directions should be in the range as given for distance rings, where possible. Resilient elements for support rings have both axial and lateral mechanical stops, to limit movements of the insulation, (even) when the resilient element fails.

Commercially available anti-vibration mountings should be used wherever possible. Where the operating temperatures prohibit the use of natural or synthetic rubber as resilient material, other

materials should be used instead. For example, steel springs in the form of a folded band or knitted metal can be substituted for rubber materials.

NOISE CONTROL ENGINEERING ASPECTS

Required Attenuation - Design Phase

The following steps may be used to estimate the required attenuation in the design phase of a plant:

a) Determine the sound pressure level at a distance of 1 meter from the bare pipe wall. Piping upstream and downstream of the source shall both be considered, separately. Both the octave band sound pressure levels and the overall A-weighted level should be determined. The method to be applied depends on the source of pipe noise under concern. (Many valve manufacturers, for example, provide calculated dB (A) levels downstream of their valves). Appendix 68 - Derivation Of Insertion Loss In Terms Of gives typical octave band spectra

If the pipe is the only source of noise in the area and is radiating under free-field conditions, the sound pressure level determined for the relevant place can be compared directly with the area noise limit and any excess noise obtained by subtraction.

Where other noise sources are also present, the total noise level should be determined before comparing with the work area noise limit. The most economical means of eliminating excess noise should then be considered; either by reducing the pipe noise or by reducing the other sources.

c) If the pipe is in a reverberant space or is subject to environmental noise limits, its sound power level should be determined. The sound power level, Lw, of the pipe is derived from:

Lw(s)=Lp(x,r) + 10 log (2πrs) In which r=distance from the pipe axis, meters

(dB)

(r normally = (1 + ½D)

(eqn. 1)

D=diameter of the pipe, meters s=The length of the pipe (s>>r), meters Lp(x, r) = the sound pressure level at a distance r from the axis of the pipe, at a distance x from the source, counted along the pipe

NOTE: The preferred value for x is 1 meter. In this subsection, where attenuation along the pipe is considered negligible, other values of x may also be used.

d) If the pipe is long, it may be worth taking into account the attenuation along the length

of the pipe, which is expressed by the formula:

(dB)

(eqn. 2)

Lp(x,r) Lp(1,r) - βx/D in which Lp(x, r) — see equation (1) Lp(1,r) the sound pressure level from the pipe at a distance of 1 meter away from the noise source, at the same distance r from pipe axis as in Lp(x,r) D the diameter of the pipe (x and D in the same units, e.g. meters) β is the attenuation factor in dB

Unless otherwise specified, the value of β shall be 0.06 dB for pipes carrying gas or vapor, and 0.017 dB for pipes carrying liquid, except that other values may be used if sufficient data is available. The length of pipe should exceed (3D/β) before attenuation should be taken into

account. If, for a particular application, firm evidence is available that the value for

different, this different value shall be used. On the basis of equation 2, the sound power level Lw of a long length of pipe can be shown to be:

rD β

4.14

(eqn. 3)

NOTE: The complete equation for the relation between Lw and Lp (1m) is:

in which

ln = logarithm to base e

(eqn. 4)

For small values of (βs/D), equation 4 can be shown to simplify into equation 1 and into equation 3 for very long pipes.

The errors involved in applying equation 1 for pipes longer than (3D/β) and in applying equation 3 for shorter pipes can be shown to be less than 3 dB.

If the sound pressure level near to a source or the sound power level of a pipe section connected to that source is known and pressure or power level has to be determined of another section under different conditions but connected to the same source, the following formula can be used to determine the difference in level due to those other conditions:

In which:

∆𝐿𝐿 = 10 log

𝑡𝑡 𝑡𝑡𝑡𝑡

− 30 log 𝐷𝐷/𝐷𝐷𝑡𝑡 − 10 log 𝑃𝑃/𝑃𝑃𝑡𝑡

= Difference in (sound pressure or power) level, dB

t = pipe wall thickness, m ∆𝐿𝐿 D = Pipe Diameter, m

P = Internal static pressure in pipe, Pa

Subscript k refers to the conditions of the known level

e) The contribution of pipe noise calculated from its sound power level and should be added to the contributions from other sources. For environmental noise, the contribution of the pipe to the sound pressure level at the neighbourhood point should be calculated. Unless otherwise specified, such calculations shall be done in accordance with EEMUA 140 or ISO 9613-2.

If allowable limits are exceeded by the combined effect of noise source, the most economical method of reducing noise that compatible with safety and minimal impact on plant operation should be found.

Required Attenuation - Operating Units

In operating units, the assessment of pipe noise can be based on measurements and, where the pipe noise is significantly higher than the background noise, it may be measured directly as airborne noise.

Again, piping upstream and downstream of the source shall be considered, separately. If the background noise prevents the measurement of sound pressure level, the pipe noise may be assessed by measuring the vibratory-velocity level:

Lp (x,r)=Lv+10 log σ + 10 log (D/2r)

(dB)

Choice of Acoustical Insulation

Where pipe noise is to be reduced, the various alternatives should be considered i.e., application of:

low-noise equipment (by design)

• • silencers • enclosures • acoustical insulation

If the assessment of various aspects of noise control indicates that the acoustical insulation of a pipe is required, the necessary reduction of pipe noise should be tabulated in octave bands. Reference to Table 27 will then indicate which class of insulation is required; see also the following section for the limits of application.

Pipes will usually have to be insulated from the source up to (and sometimes including) the next silencer, vessel, heat exchanger, filter, etc., unless it can be shown that attenuation along the pipe has reduced the noise sufficiently at some point upstream or downstream of the source to render further insulation unnecessary.

This may be the point where the contribution of the pipe to the work area noise level is below the specified value according to equation 2. Alternatively, if the sound power level of a pipe is to be reduced, the length of the pipe, L, to be insulated can be derived as follows:

D 10 β

− a 1 − R a

In which

(eqn. 6)

the reduction factor for the totally radiated sound power level

antilog {(Lw, after - Lw, before)/10}

the insertion loss factor of the acoustical insulation

antilog {(Lp, after - Lp, before)/10}

antilog (-IL/10)

the insertion loss of the insulation (see Table 27)

The symbols D and β are pipe diameter and attenuation factor, as before.

NOTE: antilog (x) means ‘ten to the power x’

The relation between the variables in equation 6 is illustrated in Graph 1 with the attenuation factor, β, taken as 0.06. This graph illustrates that reductions in sound power are limited by the performance (insertion loss) of the acoustical insulation, i.e. R shall be larger than a. It also illustrates that in some cases, it may be more economical to choose a class of cladding with higher insertion loss, because the required length is (much) less.

NOTE: Both equation 6 and Graph 1 can be used for either octave band or overall A-weighted values.

Restriction in Application

Acoustical insulation will reduce the noise radiated directly from the pipe, but there is a counteracting effect: for any residual vibrations of the insulation cladding, a larger radiating area is available than the surface area of the bare pipe. Furthermore, the cladding may have higher radiation efficiency than the pipe, at low frequencies. These effects are relatively more important on small diameter pipes and pose a limit to the applicability of the various classes of insulation. Acoustical insulation in accordance with classes B, C & D will cause a significant increase in the emission of low-frequency noise on pipes smaller than about 200 mm.

The performance of the various classes at high frequencies does not generally depend on pipe size. When selecting a class of acoustical insulation, the above-mentioned effects shall be taken into account.

The values of insertion loss given in Table 2 should be attained by an insulation system which satisfies the requirements of this specification, but the Noise Control Engineer /CONTRACTOR may apply a factor of safety to allow for possible expected deficiencies in installation and maintenance.

Implications for Piping Design

It is important to ensure at an early stage of the design that the piping arrangement allows for the bulk and mass of acoustical insulation. The Noise Control Engineer / CONTRACTOR is therefore recommended to estimate the noise levels of major piping and to mark on the process engineering flow schemes the extent and thickness of acoustical insulation for those sections of pipe which are to be acoustically insulated. At the same time, he should consider whether the substitution of low-noise sources or the use of silencers might be more appropriate.

The design of pipe supports and hangers must allow sufficient space for the installation of acoustical insulation.

The insulation shall be fitted completely around the pipe - to the extent feasible. Special care should be exercised with Class C & D insulation. Where pipes are attached to steel structures, special consideration should be given to the isolation of vibrations between the pipe and structure.

When piping is supported by or suspended from a steel structure, resilient support or hangers should be used. When class C or D insulation is to be applied. The application of resilient support or hangers may also be considered for other cases. The resilient elements shall have a mechanical stop to limit the movement of the pipe, even when the resilient element fails.

The method for supporting the piping shall be agreed between the parties responsible for the mechanical and the acoustical design.

NOTE: Spring-loaded hangers, as applied to overhead piping subject to thermal expansion, do not necessarily have a satisfactory acoustical performance.

APPLICATION OF ACOUSTIC INSULATION

General

The requirements of hot insulation Section 9 shall apply, except where modified by this section.

An essential feature of acoustical insulation is that the jacketing shall not be in direct or indirect metal- to-metal contact with the pipe. Any such contact will allow a transmission of vibrations to the jacketing which will reduce or nullify the noise reduction of the insulation. It may even enhance the noise radiation because of the greater surface area of the jacketing.

Resilient elements shall not be pre-stressed or pre-tensioned to the extent that their operational range of deflections is exceeded.

The pipe on which the acoustical insulation is to be mounted is not necessarily hot. Thus, attention shall be paid to corrosion prevention, by painting as well as the prevention of both rainwater ingress and condensation of water vapor within and upon the insulation.

For installation details, refer to Appendices 57 through 69. Additional or alternative methods of installation may be submitted to the CONTRACTOR/COMPANY for approval.

NOTE: The illustrations in the appendices show the general principles required for acoustical insulation, but the actual installation details may vary according to local circumstances.

Extent of Insulation

The length of pipe to be insulated and the class of insulation shall be as specified separately by the Noise Control Engineer / CONTRACTOR responsible for the acoustical design of the installation.

The insulation of pipe supports, flanges and valves shall be in accordance with the requirements of the class.

Anti-Vibration Seals

At positions where metal-to-metal contact would normally occur, anti-vibration seals shall be applied, see Appendix 58 - Typical Arrangement of Acoustic Insulation Showing Jacketing and End Cap and Appendix 59 - Construction Details - End Caps. They shall have a minimum thickness of 3mm and a minimum width of 50 mm

The edges of the jacketing or end cap shall be folded where they rest on the anti-vibration seal. If the seal is of porous insulation material, the outer edge shall be weatherproofed with a flexible mastic compound.

End Caps

At all exposed flanges, the acoustical insulation shall be terminated with an end cap. This cap shall be located as close to the flange as possible, but still allow bolt removal. The end cap shall be isolated from the pipe by means of an anti-vibration seal. For end caps at pipe ends, see Appendix 59 - Construction Details - End Caps and Appendix 60 - End Cap at Pipe End.

Acoustical Enclosures

When the noise radiated from a valve must be reduced, the equipment shall be surrounded by an acoustic enclosure. Flanges may also be surrounded by an acoustic enclosure or by removable insulation. Acoustic enclosures shall be easily demountable to provide access to the flange or valve. Joints shall be sealed to prevent noise leakage.

Demountable parts of acoustic enclosures shall have lifting lugs if their mass exceeds 25 kg.

AGES-SP-09-008

Rev. No: 1 Page 91 of 92

All parties consent to this document being signed electronically -PT&CS/GP/INT/2022/2410

ADNOC Classification: Internal

The acoustic enclosure shall have an outer surface of metal sheet with a mass per unit area at least equal to that of the jacketing of adjacent pipes. The porous layer shall be similar in material and thickness to that used on the piping and shall be retained by an inner surface layer with an open area of about 30%, for example, by the use of a perforated metal sheet. The inner surface layer shall be at least 10 mm away from the flange or valve.

Where acoustic enclosures are installed around flanged joints, they shall be of sufficient length to overlap the ends of the pipe jacketing by at least 100 mm for Class A and 200 mm for Classes B, C, and D, (see Appendix 62 - Arrangement for the Acoustic Insulation of Flanged Joints).

Earthing of Jacketing

Jacketing segments shall be connected in such a way that they are galvanically earthed to prevent electrostatic charging. This may be achieved either by using a fastening method that ensures an electrical connection, e.g. self-tapping screws, or by applying special braided wire between segments. The jacketing shall be galvanically connected to the pipe or any other earthed part of the structure at each end of the acoustical insulation.

Prevention of Mechanical Damage

Where acoustic insulation may be liable to mechanical damage, special provision shall be made to protect it. For example, where it may be stepped on, separately supported steps should be provided. Where mechanical load cannot be avoided, the jacketing should be reinforced by using stiffener plate(s) and additional distance rings.

Combined Thermal and Acoustical Insulation

19.8.1.1 Hot Insulation

When insulation is required for thermal as well as for acoustic reasons, the same material may be used for both purposes, provided the acoustic requirements of this specification are met. The thickness of the porous layer shall be determined by the more stringent of the two requirements and the acoustic insulation shall be installed as the outer layer

The material selection for hot insulation systems that need noise reduction (acoustic insulation design) should be such that a material is selected with low sound transmission (e.g., FEF, Mineral wool, nano porous, micro porous, flexible aerogel blanket).

19.8.1.2 Cold Insulation

Dual temperature service, cold and acoustic insulation systems shall meet the heat gain and condensation requirements specified in Part 2 of the specification and the design of the insulation system shall prevent moisture condensation and icing in the acoustic and cold insulation materials

The cold insulation system shall be applied to the pipe first, and the acoustic insulation applied on top. The density of the porous layer shall be 150 Kg/m3. . The vapor seal shall conform to Part 2 of this specification. To prevent condensation at the interface between the two layers, a second vapor seal shall be applied outside the porous layer. Care should be taken to avoid damage when applying the cladding directly over the vapor seal; rivets or self-tapping screws shall not be used.

A wet-applied vapour barrier shall not be used in acoustic insulation.

APPENDIX 68 - DERIVATION OF INSERTION LOSS IN TERMS OF DB(A)

The decision to apply acoustical insulation will usually be based on a measured or calculated noise level in dB(A) of the unsilenced pipe, but a calculation of the effectiveness of acoustical insulation in terms of dB(A) can only be done on the basis of an octave band spectrum of the noise.

Where possible the actual spectrum of the pipe under consideration should be obtained. If the noise level in dB(A) is the only quantity available, the octave band spectrum may be estimated using Table A.1. This table gives a typical spectral shape of noise from pipes attached to various types of sources in the form of a correction to be subtracted from the noise level in dB(A).

a) In gas service with gas reaching sonic velocity in the valve, typical nominal pipe diameters are 150 mm to

350 mm.

b) Typical pipe diameter exceeding 300 mm.

The effect of acoustical insulation can now be obtained by subtracting the insertion loss of the type of insulation considered, per octave band. The sound level in dB(A) after insulation may be obtained by subtracting the A-weighting factors from the octave band levels according to Table A.2 and by adding these A-weighted octave band levels using the following equation:

Lp (A) = in which Lp (A) = Lp63 =

10*log (antilog Lp63/10 + … + antilog Lp8k/10)

Similarly, insertion losses may be calculated for different types of sources and various types of insulation.

On the basis of the octave band spectra of Table A.1 of this appendix and the insertion losses of Table A1 of this specification, the following approximate insertion losses in dB(A) are obtained with the various classes of insulation for different types of source. The noise control engineer should make his own assessment based on the actual data available.
