The ADNOC Ruwais LNG Project foresees the following main components at the facility:

• Onshore LNG Liquefaction facilities for 2 x 4.8 MTPA electrically driven LNG Trains (9.6MTPA total)

• Common facilities including inlet receiving facilities, LNG storage, BOG handling, flare, refrigerant

storage and support buildings.

• Utilities to support the facilities including import power from the national grid.

• Marine facilities for LNG export and bunkering.

1.1

Scope of the Document

This specification covers the basic requirements for establishing a Positive Material Identification (PMI) procedure for alloys which are required to be verified to meet the minimum chemical requirements. The procedure will be used by the Supplier at Supplier’s facilities and at construction sites.

When this specification is included in a purchase order or subcontract, the application of PMI or Alloy Verification (AV) during the fabrication and/or receipt of alloy materials is required for equipment assemblies, piping, and bulks to be received in the field.

The PMI program as defined herein, in no way releases suppliers and fabricators from the responsibility of furnishing the specified materials and is not intended to replace the supplier’s and/or fabricator’s normal quality control procedures. Any conflict between this specification, drawings, datasheets etc. shall be brought to the attention of the CONTRACTOR in writing for clarification or corrective action

IDENTIFICATION

2.1

General

Mandatory PMI shall include those applications wherein substitution or inadvertent use of the wrong material or alloy could lead to a catastrophic failure.

Mandatory PMI shall be included in accordance with the appropriate sections of this specification for alloys applied in the following minimum listing of service environments:

a. Low chrome alloys used in High Temperature Hydrogen Service including H2pp (hydrogen partial pressures) and temperatures exceeding the carbon steel limits within API 941 shall receive 100% PMI.

b. Low chrome alloys used in 1500 psig (10.34 MPa) or higher steam service.

c. Others as defined by project environments.

d. Application of low Ni steels (2½Ni, 3½Ni and 9Ni) in low temperature.

e. Naphthenic acid service with 300 series stainless steels.

f. Duplex stainless steels in chloride service in high pressure gas plants.

g. Nickel alloys in highly corrosive service, e.g. HCl acid

PMI/AV shall be performed at the point of application at a time which ensures that proper materials have been used in the fabrication of an identifiable assembly (such as pipe lengths welded into spools or plates welded into pressure vessels). Any Pressure retaining piping bulk material procured from stockist or distributor shall be PMI tested at the Stockist / distributor.

Upon completion of fabrication or prior to release for shipment, PMI test documentation shall be made available to the Purchaser’s Inspector. The documentation shall demonstrate that PMI has been performed on individual plates, pipe, fittings, valve bodies and all other components including welding consumables that were used to fabricate items listed in Appendix 9.2. Non-permanent color coding shall be used to indicate location of PMI test. Permanent marking shall only be applied when specified in the Contract Specification. Drawings or weld maps shall be used to identify where PMI test was conducted, which corresponds to the PMI report.

After PMI testing has been successfully completed, each item component shall be marked to identify the alloy type. The preferred marking methods are low stress stamps or Vibra-etch. Other marking methods require agreement and authorization.

Certified Material Test Reports (CMTR) including those certified by a Third Party are not to be considered as a substitute for PMI/AV or vice versa.

When a “Standard” inspection sample has been accepted, each part in the inspection lot shall be marked and segregated from materials waiting to be tested as outlined in the Seller’s PMI/AV procedure. The Seller is required to provide specific details of the marking system to be utilized, subject to the Purchaser’s review and written approval.

Copies of all PMI test results shall be given to the Purchaser’s Inspector for review, immediately upon completion. The Seller’s PMI procedure shall indicate how permanent records of all PMI test results shall be documented.

Controls shall be outlined in the Seller’s PMI procedure to prevent the accidental use of any untested materials and / or materials which have failed a PMI test.

The terms of Contract / Agreement No: CON22-146 shall apply for any disclosure of this document to any third party.

When included in the scope of alloy verification by PMI, and the Code design requires a controlled carbon content, then these materials shall be identified by using a suitable portable optical emission spectrometry (OES) instrument since carbon and other lighter elements cannot be analyzed by XRF techniques. Alternately these contents can be verified by laboratory analysis from drillings from samples.

PMI testing shall be performed prior to post weld heat treatment (Unless approved otherwise by COMPANY). PMI shall be carried out prior to painting.

3.0

SPECIFIC REQUIREMENTS

3.1

Extent of testing

PMI shall be conducted on the specific components listed in Appendix 9.2 and 9.3 of the alloy groups listed in Appendix 9.1 unless specifically exempted in the Purchase Order.

For all grades of type 304 stainless steel (i.e., 304L, 304, and 304H), the extent of PMI shall be “Full” for both wrought base material and welds and subject to requirements in the notes of Appendix 9.2 and 9.3.

For all other alloy materials including all grades of Type 316 stainless steel, the extent of PMI shall be “Full” for both wrought base material and welds and subject to requirements in the notes in Appendix 9.2 and 9.3

Carbon steel components in the following services shall be verified by matching heat numbers of components to certified test certificates. Validation of this requirement shall be included in the PMI Inspection Report.

1. Sour service and hydrofluoric acid service – carbon steel materials and B7 bolting where HIC

resistant material or maximum hardness levels are specified.

2. Low Temperature (LT) service - where carbon steel with enhanced low temperature properties (e.g.

impact tested material) is specified.

3. Any other specific applications where carbon steel chemistry or properties are critical to avoid failure

and loss of containment

Carbon steel components in specialty services noted above shall remain fully traceable by heat number as PMI testing of these components is not feasible.

Pressure-containing full penetration welds and tee joints, and fillet welds of slip-on flanges in equipment and piping made with alloy welding consumables shall be 100% PMI tested and subject to the requirements in the notes in Appendix 9.2 and 9.3.

The extent of PMI testing for welding consumables shall be one electrode or wire sample from each lot or package of alloy weld rod used in shop or field fabrication. The remainder of lot should be compared to the sample to verify that the markings of the wires/electrodes are correct. PMI testing of weld metal (e.g. deposited weld metal or undiluted weld buttons) is a permissible alternative to PMI testing of an electrode or wire sample.

3.2

Acceptance criteria

Materials shall satisfy the requirements of the applicable material standards or specification (for example: ASTM or ASME composition requirements). For weld metal, the acceptance criteria shall be in accordance with the applicable AWS standard or ASME SEC II Part C.

Components or welds which are found to comply with the applicable material specification shall be accepted. If any of the major alloying elements determinations, as reported in Appendix 9.1, are outside of the range specified by the applicable material standard or if the portable analyzer indicates an incorrect match or “no

match”, the component shall be rejected, or a referee analysis shall be performed in accordance with this specification.

All unacceptable materials shall be identified, marked, removed and replaced with the specified materials.

3.3

Non Conformance

Non-conforming items or welds shall be replaced immediately or re-analyzed successfully at the Seller’s expense. The Purchaser shall be informed, in writing, of any non-conformances. The Seller’s non- conformance report (NCR) shall include a proposed corrective action plan.

If non-conforming components are detected within the lot, 100% examination of the inspection lot shall be required.

All non-conforming components shall be removed and replaced. Rejected material shall be identified by markings and segregated from acceptable material.

Rejected material shall be replaced with acceptable material. Following replacement, PMI shall be conducted on all replaced components and associated welds.

If an item from a representative sample is rejected:

1. 100% of the remaining components from which the sample was taken shall be examined

2. 100% of the components from the next delivery from the same manufacturer or supplier shall be

examined.

If no further components are rejected, the extent of examination shall return to that specified per the Contract and the extent from the forgoing “Specific Requirements” or “Random Sampling” as originally specified.

If referee examination becomes required, positive confirmation of identity shall be performed by quantitative analysis. Quantitative analysis shall provide recordable, elemental composition results for positive identification of alloying elements listed in Appendix 9.1. Alternatively, an independent laboratory analysis using any of the acceptable methods referenced in this specification may be performed. The independent laboratory shall be approved in writing by the Purchaser.

4.0

TEST EQUIPMENT

The equipment or methods used for this standard shall be able to positively identify and provide a quantitative, recordable, elemental composition measurement of the alloying elements specified in Appendix 9.1 “Alloy Elements Required for PMI Inspection”.

Testing shall be done as per the procedures outlined by the manufacturer of the alloy analyzer being used. Modification of these procedures must be approved by the Purchaser.

Each analyzer shall be calibrated according to the requirements of the manufacturer of the alloy analyzer. At the beginning and end of each shift, the instrument must be checked by the person performing the PMI against a certified standard for the alloy type to be inspected during the shift. The calibration shall also be carried out during the shift when changing the alloy family to be tested.

The person(s) performing the PMI shall demonstrate documented proof of their capabilities and experience in performing PMI. The instrument operator shall work to a written procedure and shall have been trained to use the instrument in accordance with that procedure.

The examination shall comply with the surface preparation and cleanliness requirements recommended by the instrument manufacturer as contamination of the surface can lead to inaccurate results.

The terms of Contract / Agreement No: CON22-146 shall apply for any disclosure of this document to any third party.

1. Where specified/applied in high temperature service per Code or where in High Temperature Hydrogen service (API RP941), all austenitic H-grades require analysis of Carbon Content for conformance with the Material Specification. Since “sorting” cannot be accomplished by XRF techniques, portable OES or spark techniques shall be employed; or drillings for wet-lab analysis can be substituted. Since “L”-grades do not represent Code required design (e.g., potential liabilities as in the case of “H”-grades) nor are these a potential catastrophic mix- up event and therefore do not require sorting (including where defined within pressure boundary weldments).

2. Tantalum and Zirconium alloys are to meet their respective ASTM material specifications.

3. The list of materials is not exhaustive and shall not be considered as limiting the alloy metals to PMI. For alloy materials not covered in the table, the supplier shall seek Purchaser approval for elements to be analyzed.

4. Alloy 400 weld consumables shall contain Ti < 2.2% wt. and Fe < 5% wt. in Hydrofluoric acid service.

Notes:

1. 10% of all the components purchased shall be examined. Components to be examined shall be selected by the

purchaser. If any given sample of components has few than 10 items, one item shall be examined.

2. 1% representative sample of the total number of tubes from each heat, lot and material specification of tubes or a minimum of 5 tubes per heat/lot, whichever is greater, shall be tested. If one of the tubes is found unacceptable, all the other tubes of the same lot shall be tested.

3. 5% of bolts supplied in bulk or two bolts per box and per heat and lot, whichever is greater, shall be examined.

Bolts to be examined shall be selected randomly by the purchaser.

4. One examination per heat of material.

5. One spot on every cap pass of every pressure retaining weld shall be examined in accordance with Table above.

6. One spot on one cap pass per weld procedure per spool of piping shall be examined in accordance with table

above.

7. Valve body and bonnet only. However PMI testing of non-standard trim upgrades using high alloy material such as alloy 400 trim is recommended in the modification shop. Internal bonnets as found on “power seal” type valves are considered internal components as they typically cannot be accessed by PMI analyzers.

8. Analysis of the weld overlay shall be performed on PQR test coupons to verify the specified alloy chemical composition and that the degree of alloy dilution is acceptable at the designated depth. This analysis shall include:

If the function of the overlay is corrosion protection, a volumetric or surface analysis shall be completed at a minimum depth of 1.5mm (0.06”) below the process-contacted surface.

If the function of the overlay is to assure product purity only, the sample shall be taken at a minimum depth of 1mm (0.04”).

In cases of in-accessibility a weld test sample should be completed for analysis, and tested per a) or b). The test sample shall be welded for each welding process and for each heat and lot of filler materials.

9. One analysis per weld procedure shall be taken of the base filler material and/or overlay finished weld per note 8 (e.g. covering a base metal weld or joining the cladding of clad plates) on each major longitudinal and circumferential weld seam. Refer to the requirements for the following specific components: a. Nozzles: For nozzles and components lined with alloy weld metal overlay, one analysis per nozzle is required. For sleeve lined nozzles, one analysis for the flange face overlay and of the shell tie-in overlay is required.

b. Alloy Air Cooler Header Boxes: one analysis for each welding procedure used for long seams, end plates

and nozzles is required.

c. Machined components: the PMI analysis shall be completed on the finished machined components.

10. Analysis of the base filler metal and/or final closure weld seams of internally clad or weld overlaid components

shall be made at location determined by the purchaser’s designated Inspector.

11. 5% of spiral wound gaskets shall be tested when the windings or ID ring are higher alloy than 304SS. The PMI

shall be of the area at the ends where there is no filler or if provided, the ID ring.

12. Equipment and piping fabricated of alloy material solely to maintain product purity is subject to 10% PMI including welds, with exception of 304, 304L, 304H or 316, 316L, 316H, unless otherwise specified by the Purchaser.

13. 100% of B7M bolting for HFA and sour service (if applicable) shall be tested for hardness as a part of the PMI

program.

14. Carbon steel and Alloy 400 intended for Hydrofluoric Acid service requires “Full” testing.

15. All piping bulk materials shall be verified to be delivered with the original Manufacturer’s markings clearly

readable.

16. Exempt from PMI- The following components are exempt from PMI requirements, unless specifically designated

for PMI in the contract documents:

a. All components and welds manufactured from materials excluded from PMI (materials not listed in Appendix

9.1).

b. All grades of carbon steel for use in normal refinery and chemical plant service. c. Electrical components. d.

Internal valve components that are standard from the Manufacturer. Note: High alloy valve trim upgrades that are performed in a valve modification shop are not exempt. Internal parts of machinery and pumps made of type 304, 316 stainless steel or brass. Instrumentation, such as orifice plates, venture internals; and secondary (e.g. that is downstream of primary block valve) tubing and components that are made from 304, 304L, 316 and 316L stainless steel or copper.

e. f.

g. All cast brass valves. h. Auxiliary equipment such as machinery lube oil systems, hydraulic systems, steam tracing, steam turbine

gland vacuum systems and instrument air.

i. Standard (304 stainless steel) spiral wound gasket materials. Higher alloy spiral wound gasket materials

require PMI testing based on Appendix 9.2 minimum requirements.
