【国外标准】 Standard Specification for Nickel-Alloy (UNS N06625, N06219 and N08825) Welded Pipe

This specification covers UNS N06625, N06219, and N08825 nickel-alloy welded pipe in the annealed condition. The pipe shall be manufactured from flat-rolled alloy by an automatic welding process with no additional filler metal. The pipe material shall be cold-worked, annealed, and nondestructively tested. The pipe shall be furnished with oxide removed. The material shall conform to the composition required by the specification. The pipe shall be subjected to tensile, yield, elongation, transverse guided bend, and nondestructive test requirements. Nondestructive test includes hydrostatic, pneumatic, eddy current, ultrasonic, leak, and electric testing. Acceptable size limit of cracks or other defect after bending test is specified.1.1 This specification covers welded UNS N06625,2 UNS N062192 and UNS N088252 pipe in the annealed condition (temper) for general corrosion applications.1.2 This specification covers pipe sizes in schedules shown in the Permissible Variations in Outside Diameter and Wall Thickness for Welded Pipe table of Specification B775.1.3 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.1.4 The following precautionary caveat pertains only to the test methods portion, Section 8, of this specification: 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.
