Section XIII-1321 - Inspection and Test of Welds [49 CFR 192.241]

A. Visual inspection of welding must be conducted by an individual qualified by appropriate training and experience to ensure that [ 49 CFR 192.241(a)]:

2. the weld is acceptable under Subsection C of this Section. [ 49 CFR 192.241(a)(2)]

B. The welds on a pipeline to be operated at a pressure that produces a hoop stress of 20 percent or more of SMYS must be nondestructively tested in accordance with §1323, except that welds that are visually inspected and approved by a qualified welding inspector need not be nondestructively tested if: [ 49 CFR 192.241(b)]

1. the pipe has a nominal diameter of less than 6 inches (152 millimeters); or [ 49 CFR 192.241(b)(1)]

2. the pipeline is to be operated at a pressure that produces a hoop stress of less than 40 percent of SMYS and the welds are so limited in number that nondestructive testing is impractical. [ 49 CFR 192.241(b)(2)]

C. The acceptability of a weld that is nondestructively tested or visually inspected is determined according to the standards in section 9 of API Std 1104 (incorporated by reference, see §507). Appendix A of API Std 1104 may not be used to accept cracks. [ 49 CFR 192.241(c) ]
