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.[Eff ] (Auth: HRS § 269-6) (Imp: 49 C.F.R. §192.107, OCT 1, 1990)
