1、Designation: B675 02 (Reapproved 2013)Standard Specification forUNS N08367 Welded Pipe1This standard is issued under the fixed designation B675; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in
2、 parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers UNS N08367* welded pipe forgeneral corrosion applications.1.2 Specification B775 lists the dimensions of welded stain-
3、less steel pipe as shown in ANSI B36.19. Pipe having otherdimensions may be furnished provided such pipe complieswith all other requirements of this specification.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to S
4、I units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including those identified i
