ASTM International Standard Specification for Welded Nickel and Nickel-Cobalt Alloy Pipe ASTM B619-06

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 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.
