(Specification)Standard Specification for General Requirements for Alloy and Stainless Steel Pipe
Standard Specification for General Requirements for Alloy and Stainless Steel Pipe
SCOPE
1.1 This specification covers a group of general requirements that, unless otherwise specified in an individual specification, shall apply to the ASTM product specifications noted below.
1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail.Title of SpecificationASTM DesignationSeamless and Welded Austenitic Stainless Steel PipeA 312/A 312MSeamless and Welded Steel Pipe for Low-Temperature ServiceA 333/A 333MSeamless Ferritic Alloy-Steel Pipe for High Temperature ServiceA 335/A 335MElectric-Fusion-Welded Austenitic Chromium-Nickel Alloy Steel Pipe for High-Temperature ServiceA 358/A 358MCarbon and Ferritic Alloy Steel Forged and Bored Pipe for High-Temperature Service A 369/A 369MSeamless Austenitic Steel Pipe for Use With High Temperature Central-Station Service A 376/A 376MWelded Large Diameter Austenitic Steel Pipe for Corrosive or High-Temperature ServiceA 409/A 409MWelded, Unannealed Austenitic Stainless Steel Tubular ProductsA 778Seamless and Welded Ferritic/Austenitic Stainless Steel PipeA 790/A 790MSingle- or Double-Welded Austenitic Stainless Steel PipeA 813/A 813MCold-Worked Welded Austenitic Stainless Steel PipeA 814/A 814MFerritic/Austenitic (Duplex) Stainless Steel Pipe Electric Fusion Welded with Addition of Filler MetalA 928Spray-Formed Seamless Austenitic Stainless Steel PipeA 943Spray-Formed Seamless Ferritic/Austenitic Stainless Steel PipeA 949Austenitic Chromium-Nickel-Silicon Alloy Steel Seamless and Welded Pipe A 954
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. With the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation (SI) of the product specification is specified in the order.
Note 1--The dimensionless designator NPS (nominal pipe size) is used in this standard for such traditional terms as "nominal diameter," "size,"" nominal bore," and "nominal size".
1.4 The following precautionary statement pertains only to the test method portion, Section 21, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
