ASTM B619 / B619M Standard Specification for Welded Nickel and Nickel-Cobalt Alloy Pipe
This specification covers welded pipe of nickel and nickel-cobalt alloys (UNS N10001; UNS N10242; UNS N10665; UNS N12160; UNS N10624; UNS N10629; UNS N10675; UNS N10276; UNS N06455; UNS N06007; UNS N06975; UNS N08230; UNS 06002; UNS N06022; UNS N06035; UNS N06058; UNS N06059; UNS N06200; UNS N06985; UNS N06030; UNS R30556; UNS N08031; UNS N06230; UNS N06686; UNS N06210; and UNS R20033). Two classes of pipe are covered as Class I which is as welded and solution annealed or welded and sized and solution annealed; and Class II which is welded, cold worked, and solution annealed. All pipes shall be furnished in the solution annealed and descaled condition. The pipe shall be made from flat-rolled alloy by an automatic welding process with no addition of filler metal. Subsequent to welding and prior to final heat treatment, Class II pipes shall be cold worked either in both weld and base metal or in weld metal only. The material shall conform to the composition limits set by this specification. Tensile strength, yield strength and elongation of the material shall conform to the mechanical requirements. Tension test, flattening test, transverse guided bend test, and hydrostatic or nondestructive electric test shall be performed.
1. Scope

1.1 This specification covers welded pipe of nickel and nickel-cobalt alloys (UNS N10001; UNS N10242; UNS N10665; UNS N12160; UNS N10624; UNS N10629; UNS N10675; UNS N10276; UNS N06455; UNS N06007; UNS N06975; UNS N08320; UNS N06002; UNS N06022; UNS N06035; UNS N06044; UNS N06058; UNS N06059; UNS N06200; UNS N10362; UNS N06985; UNS N06030; UNS R30556; UNS N08031; UNS N08034; UNS N06230; UNS N06686; UNS N06210; and UNS R20033)3 as shown in Table 1.

(A) The composition of the remainder shall be determined arithmetically by difference.
1.2 This specification covers pipe in Schedules 5S, 10S, 40S, and 80S through 8-in. nominal pipe size and larger as set forth in ANSI B36.19 (see Table 2).

(A) Schedules 5S and 10S wall thicknesses do not permit threading in accordance with ANSI B2.1-1960.
1.3 Two classes of pipe are covered as follows:

1.3.1 Class I—As welded and solution annealed or welded and sized and solution annealed.

1.3.2 Class II—Welded, cold worked, and solution annealed.

1.4 All pipe shall be furnished in the solution annealed and descaled condition. When atmosphere control is used, descaling is not necessary.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.6 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 Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
