HAR 6-77-30 Yield strength (S) for steel pipe

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#
