Current through September, 2024
Section 6-77-30 - Yield strength (S) for steel pipe
(a) For pipe that is manufactured in accordance with a specification listed in section I of Appendix B, the yield strength to be used in the design formula in section 6-77-29 is the SMYS stated in the listed specification, if that value is known.
(b) For pipe that is manufactured in accordance with a specification not listed in section I of Appendix B or whose specification or tensile properties are unknown, the yield strength to be used in the design formula in section 6-77-29 is one of the following:
(1) If the pipe is tensile tested in accordance with section II.D. of Appendix B, the lower of the following:
(A) Eighty percent of the average yield strength determined by the tensile tests;
(B) The lowest yield strength determined by the tensile tests, but not more than 52,000 p.s.i.
(2) If the pipe is not tensile tested as provided in subsection (b)(1) 24,000 p.s.i.
