ASTM B673-05(2016)

Standard Specification for UNS N08925, UNS N08354, and UNS N08926 Welded Pipe

ABSTRACT
This specification covers UNS N08925, UNS 8354, and UNS N08926 welded pipes of specific dimensions for general corrosion applications. The pipe shall be made from flat-rolled alloy by an automatic welding process with no addition of filler material. Class 1 and Class 2 material shall be cold worked either in both weld and base metal or in weld metal only, subsequent to welding and before final solution treatment. The tensile strength, yield strength, and elongation requirements shall conform to specified values. The pipes shall be subjected to random flattening, leak, and electric tests.
SCOPE
1.1 This specification covers UNS N08925, UNS N08354, and UNS N089262 welded pipe for general corrosion applications.  
1.2 This specification covers pipe sizes in schedules shown in Table 1. (A) Schedule 5S and 10S wall thicknesses do not permit threading in accordance with ANSI B2.1.(B) These do not conform to ANSI B31.10.(C) These do not conform to ANSI for Welded and Seamless Wrought Steel Pipe (ANSI B36.10).  
1.3 ASTM International has adopted definitions whereby some grades, such as UNS N08904, previously in this specification were recognized as stainless steels, because those grades have iron as the largest element by mass percent. Such grades are under the oversight of ASTM Committee A01 and its subcommittees. The products of N08904 previously covered in this specification are now covered by Specification A312/A312M.  
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 Safety Data Sheet (SDS) 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.
