Haw. Code R. § 6-77-80 - Inspection and test of welds

(a) Visual inspection of welding must be conducted to insure that:

(1) The welding is performed in accordance with the welding procedure; and

(2) The weld is acceptable under subsection (c);

(b) The welds on a pipeline to be operated at a pressure that produces a hoop stress of twenty percent or more of SMYS must be nondestructively tested in accordance with section 6-77-81, except that welds that are visually inspected and approved by a qualified welding inspector need not be nondestructively tested if:

(1) The pipe has a nominal diameter of less than six inches; or

(2) The pipeline is to be operated at a pressure that produces a hoop stress of less than forty percent of SMYS and the welds are so limited in number that nondestructive testing is impractical.

(c) The acceptability of a weld that is nondestructively tested or visually inspected is determined according to the standards in section 6 of API Standard 1104.
