1.1 This specification contains various requirements that, with the exception of Section 5 and Section 10, are mandatory requirements to the following ASTM nickel and nickel alloy, longitudinally welded piping specifications:

Title of SpecificationASTM
Designation Welded UNS N08020, N08024, and N08026 Alloy PipeB 464 Welded Nickel-Iron-Chromium Alloy PipeB 514 Welded Nickel-Chromium-Iron-Alloy (UNS N06600,
UNS N06603, UNS N06025 and UNS N06045) PipeB 517 Welded Nickel and Nickel-Cobalt Alloy PipeB 619 UNS N08904, UNS N08925, and UNS N08926 Welded PipeB 673 UNS N08367 Welded PipeB 675 Nickel-Alloy (UNS N06625, N06219, and N08825) Welded PipeB 705 Ni-Cr-Mo-Co-W-Fe-Si Alloy (UNS N06333) Welded PipeB 723 Welded Nickel (UNS N02200/UNS N02201) and Nickel
Copper Alloy (UNS N04400) PipeB 725

1.2 One or more of the test requirements of Section 5 apply only if specifically stated in the product specification or in the purchase order.

1.3 In case of conflict between a requirement of the product specification and a requirement of this general specification, only the requirement of the product specification needs to be satisfied.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
