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,* UNS N06219* and UNS N08825* 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 B 775.

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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) 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.
