1.0 GENERAL

1.1 SCOPE

This specification lists appropriate standards for metallic construction materials.

1.2 PURPOSE

In situations where required materials are not explicitly specified, this specification shall beinvoked to act as a basis for the CONTRACTOR’S materials selection.

It should be realized that materials may fail owing to undesirable properties being inducedduring fabrication and/or service, such as metallurgical changes or corrosion of various

types. Such factors shall be taken into account when selecting a material for a givenservice. Measures which may be required to prevent or limit such risks (e.g. special heattreatment) are outside the scope of this specification and are not indicated. Al l selectionof materials should therefore be done by qualified personnel and shall be submittedto COMPANY/CONTRACTOR for approval.

1.3 REGULATORY CONSIDERATIONS

If national and/or local regulations exist in which some of the requirements may be morestringent than in this specification, it shall be the CONTRACTOR’s responsibility todetermine which of the requirements are the more stringent and which combination ofrequirements will be acceptable as regards safety, environmental, economic and legalaspects. In all cases the CONTRACTOR shall inform the COMPANY of any deviation from

the requirements of this specification which is considered to be necessary in order tocomply with national and/or local regulations. The COMPANY may then negotiate with the Authorities concerned with the object of obtaining agreement to follow this specification asclosely as possible.

1.4 STANDARDS

This specification identifies materials to the standards of the American Society for Testingand Materials (ASTM). Where metric versions of ASTM standards are available (e.g. ASTM A278M) they should be selected. In most cases, ASTM standards and their metricversions are issued as a single standard (e.g. ASTM A182/A182M). Standards from the American Society of Mechanical Engineers (ASME) that are equivalent to the listed ASTMstandards may be used with the listed added requirements.

Other standards, e.g., ISO, BS, JIS, DIN, etc., may be used only in cases where ASTMstandards are unavailable and only with COMPANY approval. In order to avoid confusionand to provide a consistent basis for the basic specification of the materials, only oneseries of standards should be used for any particular piece of equipment (i.e. avoidmixing ASTM standards with other standards).

Where a deviation from this rule is required, agreement shall be obtained from theCOMPANY.

8/13/2019 25652-2000-3PS-NW00-N0008-Att001r001v2_0




Rev-1 March 2009


The use of trade names for materials shall be avoided whenever an authoritative

specification reference is available.

1.5 SPECIFICATION OF MATERIALS

Materials standards identified on drawings, requisition sheets or other documents shall bespecified fully in accordance with the information given in Sections 2, 3 and 4, including alladditional requirements applicable to the standard. For materials identified with a Materialsand Equipment Standards Code (MESC) number, the additional requirements statedtherein shall also be met.

The latest issue of the selected materials standard shall be used. As this latest issue(including amendments) always prevails, the year of issue of the standard need not beshown.

1.6 SPECIFICATION DEVIATION/CONCESSION CONTROL

Any technical deviations to this specification shall be sought by the CONTRACTOR orVENDOR only through CONCESSION REQUEST format. CONCESSION REQUESTSrequire CONTRACTOR'S and COMPANY’S review/approval, prior to the proposedtechnical changes being implemented. Technical changes implemented prior to COMPANYapproval are subject to rejection.

1.7 METAL TEMPERATURE LIMITS

The temperature limits shown in Sections 2, 3 and 4 are approximate limits allowed for theaverage temperature through the cross-section of the construction material during normal

operation.

The values mentioned should be regarded as an indication only and do notnecessarily apply to cases where corrosion and/or conditions which may affect thestructure of the material occur.

It should be noted that the indicated temperature limits do not necessarily exclude theapplication of the materials beyond these limits, especially for non pressure-retaining partssuch as internal parts of columns, baffles of heat exchangers, supporting structures, etc.

Temperatures shown in brackets, e.g. (+400), are unusual for the indicated application butare allowable from a materials point of view, if so required.

Special attention should be given to the specification and application of metals for serviceat low temperatures. For low temperature applications, refer to the appendices of ProjectSpecifications DGS-MW-001 “Welding, NDE and Prevention of Brittle Fracture of PressureVessels and Heat Exchangers” and DGS-MW-002 “Welding, NDE and Prevention of BrittleFracture of Piping.”

Materials for vessels and heat exchangers in low temperature service shall be limited asfollows:

Rev-1 March 2009


T≥-45ºC : carbon steel (or LTCS where required by code)

T < -45ºC : austenitic stainless steel

1.8 CATEGORIES OF METALS

The following categories of metals are covered by this specification:

Ferrous metals - unalloyed

Ferrous metals - alloyed

Nonferrous metals

In each category the following products are dealt with:

Plates, sheets and strip;

Tubes and tubing;

Pipe;

Forgings, flanges and fittings;

Castings;

Bars, sections and wire;

Bolting.

1.9 SEQUENCE OF MATERIALS

The sequence of materials in the column "Designation" in Sections 2, 3, and 4 is generallysuch that the subsequent number indicates a material with an increase in the content and/ornumber of the alloying elements.

1.10 CHEMICAL COMPOSITION

Chemical composition requirements shown in Sections 2, 3, and 4 relate to productanalyses.

Percentage compositions listed in Sections 2, 3, and 4 are by mass.

1.11 DEFINITIONS

For the purpose of this specification, the following definitions shall apply:

CONCESSION REQUEST - A deviation requested by the CONTRACTOR,SUBCONTRACTOR, or VENDOR, usually after receiving the contract package or Purchase

8/13/2019 25652-2000-3PS-NW00-N0008-Att001r001v2_0




Rev-1 March 2009


Order. Often, it refers to an authorization to use, repair, recondition, reclaim or release

materials, components or equipment already in progress or completely manufactured butwhich does not meet or comply with COMPANY requirements. A CONCESSION REQUESTis subject to COMPANY approval.

SHALL - Indicates a mandatory requirement.

SHOULD — The use of the word “should” indicates a strong recommendation to complywith the requirements of this document.

The phrase "capable of" as used in this specification means that the test need not beperformed by the manufacturer of the material. However, should subsequent testing by theCOMPANY establish that the material does not meet these requirements, the material shallbe subject to rejection.

1.12 ADDITIONAL LIMITATIONS ON MATERIALS

The following requirements shall be met unless COMPANY approval for deviations isobtained:

No grade 70 carbon steels shall be used, except SA-516 Grade 70 (subject toCOMPANY approval for the particular application, the conditions applicable to Grade65 and the additional conditions a and b listed below), ASTM A 350 LF2, wherespecified, and ASTM A 537 Cl.1 for tanks. Any other grade 70 materials orapplications require COMPANY approval except for standard carbon steel forgingsand castings eg ASTM A105, A216 WCB, A350 LF2 and A352 LCC.

a) Steel maker to provide weldability data for SA-516, Grade 70 used on previoussuccessful projects

b) Heat treatment condition: Normalised, regardless of thickness.

The carbon equivalent for all carbon steel components in non-sour service shall be inaccordance with the following table:

ComponentsMax. CarbonContent (%)

Max. CarbonEquivalent (%)

Pressure-containing plates, sheets, strips,

pipes, wrought fittings

0.23% 0.43%

Nonpressure-containing plates, bars,structural shapes and other components tobe welded

0.23% N/A

Pressure-containing forgings and castings 0.25% 0.43%
