Page 1Feb 16 1979 Mr. Gary Faulkenberry Continental-Emsco Company P.O. Box 401388 Garland, Texas 75040 Dear Mr. Faulkenberry: Your letter of December 5, 1978, refers to Title 49 CFR Section 192.149 Standard Fittings, Paragraph (b), the second sentence, which reads in part, "The actual burst strength of the fitting must at least equal the computed burst strength of the pipe of the designated material and wall thickness...." Your specific question was, "Is there a formula you can recommend to use that will adhere to the guidelines set in Section 192.149, Paragraph (b)?" The requirement of this section is based on Paragraph 8 of ASA-B16.9, "Wrought Steel Buttwelding Fittings" (1964 Edition) which does include a simple hoop stress formula for computing burst strength. A photo copy of this paragraph is enclosed for your information. Sincerely, Cesar DeLeon Associate Director for Pipeline Safety Regulation dal\192\149\79-02-19 1#
