Standard Specification for UNS N08367 and UNS N08926 Welded Pipe
ABSTRACT
This guide covers UNS N08367 and UNS N08926 welded pipe for general corrosion applications. The joints of the specimens shall be double or single welded and full penetration welded made. The welds shall be made either manually or automatically by an electric process involving the deposition of filler metal according to the class specified. The weld surface on either side of the weld shall be flush with the base plate. The contour of the reinforcement shall be reasonably smooth and free of irregularities. The deposited metal shall be fused uniformly into the plate surface. Transverse tension tests shall be made across the welded joint to assure that it must have the same minimum ultimate tensile strength as the specified minimum ultimate tensile strength of the plate. Transverse guided weld bend test shall be used to check cracks or other imperfections. The pipe shall be furnished with smooth ends, free of burrs and injurious defects and shall have a workmanlike finish.
SCOPE
1.1 This specification covers UNS N08367 and UNS N08926 welded pipe for general corrosion applications. (Although no restrictions are placed on the sizes of pipe that may be furnished under this specification, commercial practice is commonly limited to sizes not less than 8 in. nominal diameter.)
1.2 Six classes of pipe are covered as follows:
1.2.1 Class 1 pipe shall be double welded by processes employing filler metal in all passes and shall be completely radiographed.
1.2.2 Class 2 pipe shall be double welded by processes employing filler metal in all passes. No radiography is required.
1.2.3 Class 3 pipe shall be double welded by processes employing filler metal in all passes except the inside root weld may be made without the addition of filler metal. Welds are to be completely radiographed.
1.2.4 Class 4 pipe shall be double welded by processes employing filler metal in all passes except the inside root weld may be made without the addition of filler metal. No radiography is required.
1.2.5 Class 5 pipe shall be single welded by processes employing filler metal in all passes except that the pass exposed to the inside pipe surface may be made without the addition of filler metal. Welds are to be completely radiographed.
1.2.6 Class 6 pipe shall be single welded by processes employing filler metal in all passes except that the pass exposed to the inside pipe surface may be made without the addition of filler metal. No radiography is required.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
The following safety hazards caveat pertains only to the test methods portion, Section 12, of this standard: 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.
