GENERAL REQUIREMENT

Supports will be designed in such a way as to comply with good engineering practice and for critical lines with the results of the stress analysis.

The following rules shall be observed:

Supports shall be designed and installed in such a way to guarantee free thermal expansion of piping and to avoid excessive sagging, vibrations, and overloads on equipment nozzles.

All piping shall be adequately supported by hangers or supports by proper structural design. The support structures shall be strong enough to bear the calculated loads. When formal calculation is not available supports design shall as a minimum take into consideration pipe weight, fluid density, valves or heavy instruments, insulation, significant occasional loads (such as earthquake or PSV forces) and hydraulic test.

Piping connected to valves, static equipment, or machines such as pumps and compressors, requiring periodical maintenance and shall be supported to allow their removal or disconnection, reducing the necessity to install temporary supports.

It is a Construction Contractor responsibility for the supply and installation of shims that may be required for any reasons under supports (e.g., adjustments, slope requirements) up to a maximum thickness of 4’’ (100 mm), using minimum number of shim plate. Shims under base elbow supports shall be stitch welded to the support after all joints in the piping are made up. Shims under other pipe or sliding supports shall be stitch welded to support cross arms after all piping joints are made up.

The Construction Contractor shall fabricate all the brackets, T-posts, Goalposts, beams, welded or bolted extensions, dummy pipes, and hangers in order to allow field adjustment up to 100 mm as considered necessary.

As a general requirement, pipe supports providing rotational restraints should be avoided. Exceptions may be allowed in some cases where this kind of support is necessary to reduce loads on nozzle (e.g. on compressor discharge lines). In any case, supports providing a rotational restraint shall be designed as a special support by Tecnimont stress department.

Generally, the following to be avoided:

Cantilever supports from webs of beams. Support fixed to bracing. Supports which will cause torsion on the structural steel member without informing Civil Department.

REQUIREMENTS FOR PAINTING

Support shall be painted in accordance with the requirements set in General Painting Specification 4439-VW-SG-000000001

HYDRAULIC TEST

The supports design and the evaluation of piping loads on civil structures shall consider the hydraulic test load. For all the lines the information regarding test type and condition will be identified on line list or in a dedicated document. Temporary supports in hydraulic test case should be avoided as much as possible and used only where permanent supports cannot be used.

9.2 Welded Supports

Welding procedure of supports shall be in accordance with document 4439-XH-SW-000000001 – Piping Welding General Specification

The use of welded pipe supports should be limited in the following cases:

Pipes requiring post welding heat treatment.
Pipes made of expensive materials such as titanium, high alloyed steel, etc.
Galvanized piping
Pipe plastic lines
Pipe internally lined with non-metallic material.
Pipes made of stress relieved material.

When the support welded solution cannot be avoided (i.e., trunnion for long riser/downcomers lines, axial stop with high loads, stop pads, etc…), on line with PWHT will be provided a post weld heat treatment after support installation on main pipe and for galvanized lines the support will be pre- fabricated together with main pipe and complete assembly will be galvanized.

The dummy support shall not create excessive stresses at the attachment welds to the run pipe. Thus, the length of the supports should be minimized accordingly with the existing supporting structure. When allowable loads on dummy pipe are not defined by relevant Standard, the support shall be verified according to the M. W. Kellogg Company Design Manual.

9.3 Pipe Saddles and Reinforcing Pad

9.11 Supports for lines subject to A.I.V.

Some large-bore lines may be affected by Acoustic Induced Vibration (A.I.V.) of pipe shell. The list of lines potentially subject to A.I.V. is defined by Process Department and then transmitted to Piping Department. Lines subject to A.I.V. require clamped support or full encirclement reinforcement at each support location. For this purpose, a pipe shoe with reinforcing pad shall be used (i.e., Tecnimont standard shoe C2/C4) and two additional reinforcing pads (i.e. Tecnimont standard P27A) shall be applied, in order to achieve a 360° reinforcing pad. The resulting arrangement is shown in the reference drawing here below, where lower P27A is part of standard shoe C2/C4.

SELECTION OF BASE SUPPORT ON R.C. PAVING OR SLAB

The selection of the base support depends on the type of restraint of line and the loads acting on it. Expansion bolts, anchoring the support base plate to the concrete paving or slab, can be used if the following cases are verified:

Base supports on R.C. Paving Vertical Load ≤ 15.0 KN

Base supports on R.C. Slab Vertical Load ≤ 6.0 KN

Combined Moments ≤ 3.0 KNm

(The combined moments depend on the horizontal loads and on the distance from the anchoring point to the force application point)

When the loads exceed the above-mentioned combinations, a concrete foundation, to be designed by Civil Dept., should be used to anchor the support plate, casting of these foundations will be in CIVIL contractors’ scope of work. For all other foundations experiencing lesser loads than the loads mentioned above, casting of pipe support foundation should be in Mechanical contractor’s scope of work.

MAXIMUM DISTANCE BETWEEN SUPPORTS AND SELECTION OF STANDARDS SUPPORT TYPE

Distances as per Tab.1 & 3 are calculated with reference to a 20°C ambient temperature. When the design temperature of the piping to be supported exceeds the ambient temperature, calculate the new distance by multiplying the table value by factor “KS”(Tab.5) relevant to the temperature and material of the piping under consideration.

EXAMPLE: Water-filled piping, DN 300 (NPS 12”) - STD Schedule – LTCS - 150° C Design temperature – 8 m distance (as per Tab.1 & 3) and 0.96 factor as per (Tab.2 & 4). New distance  8 ÷ 0.96 = 7.68m

The pipe thickness considered is as per the ANSI / ASME CODES B36.10 and B36.19, less fabrication tolerance (12.5% of the nominal value) less corrosion allowance as per Tab.1 & 3. For piping with thickness other than those considered, calculate the new distance between supports by multiplying the values as per Tab.1 & 3 by the T 1.5/ t 1.5 ratio where:

T = New thickness (nominal thickness less fabrication tolerances less the corrosion allowance of the piping); t = Thickness considered (nominal thickness less fabrication tolerances less corrosion allowance as per Tab.1 & 3); EXAMPLE: Water - filled piping, DN 300 (NPS 12”)- STD Schedule (9.53mm thickness)- LTCS- 6mm corrosion allowance and 8m distances between supports as per Tab.1 & 3. T= 9.53 - (12.5 x 9.53 / 100) - 6 = 2.33 mm t= 9.53 - (12.5 x 9.53 / 100) - 2.5 = 5.83 mm 1.5

1.5

New distance 

/tT 8



m2.02

If both conditions 1) and 2) exist, the new distance shall be calculated as follows: distance as per (Table 1 & 3) x KS x T1.5/t 1.5) New distance  8x0.96x2.33 1.5/5.83 1.5 = 1.94 m.

The new distance as per Tab.1 & 3 are referred to the following:

Constant-interval continuous supports with no change in direction; Piping without elements generating concentrated loads (pipe alone); A 12mm max deflection measured at the center of tabulated distances; The corrosion allowance indicated in TAB. 1 & 3 for LTCS and Alloy Steel; Fabrication tolerances equal to 12.5 % of nominal pipe thickness; 0.4 Sh. max admissible stress (Sh=admissible stress as per applicable ASME B31.3 code )

FOR DISTANCES LONGER THAN TABULATED, A STRESS ANALYSIS SHALL BE MADE.
