Yield Strength (S) for Steel Pipe

§ 192.107 Yield Strength#

(S)for Steel Pipe#

(a)For pipe that is manufactured in accordance with a specification listed in Section I of Appendix B of this part, the yield strength to be used in the design formula in § 192.105 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 to this part or whose specification or tensile properties are unknown, the yield strength to be used in the design formula in § 192.105 is one of the following:#

(1)If the pipe is tensile tested in accordance with Section II-D of Appendix B to this part, the lower of the following:#

(i)80 percent of the average yield strength determined by the tensile tests.#

(ii)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 Subparagraph#

(b)(1)of this paragraph, 24,000 p.s.i. (165 MPa).#
