McIntosh\nR&G Sloane Manufacturing Company, Inc.\n7606 North Clybourn Avenue\nP.O. Box 876\nSun Valley, California 91352\nDear Mr. McIntosh:\nThis is in response to your letter of November 30, 1971 to Mr. F.E. Fulton. The following is our\ninterpretation concerning the use of plastic valves in gas pipeline systems.\nThe minimum safety standards for the Transportation of Natural and Other Gas by Pipelines (49\nCFR part 192) do not include any specifications for nonmetallic valves. Neither do these\nregulations prohibit the use of nonmetallic valves so long as the valves meet the appropriate\nrequirements of the regulations. Any nonmetallic valve Used in a gas pipeline system would be\nrequired to at least meet the requirements in Section 192.143. In the case of thermoplastic\nValves, as a means of meeting the requirements of section 192.143, it would be expected that\nthe valves at least Meet the appropriate safety design limitations of Sections 192.121, 192.123,\n192.191, or equivalent, and the appropriate sections of the referenced ASTM D-2513\nspecifications.\nThank you for your interest in pipeline safety.\nSincerely,\nORIGINAL SIGNED BY ROBERT M. CRAIG\nJoseph C. Caldwell\nActing Director\nOffice of Pipeline Safety\n\n<<<PAGE 2>>>\n\nR&G Sloane Manufacturing Company, Inc.\n7606 North Clybourn Avenue\nP.O.

W.\nWashington, DC 20590\nRE: FEDERAL REGISTER, VOLUME 35, #161, PART TWO DEPARTMENT OF TRANSPORTATION\nDear Mr. Fulton:\nWe would like clarification and instructions on the use of PVC thermoplastic valves in\nthermoplastic piping systems for gas distribution as 192-145 does not include any type of plastic\nvalves.\nThe valve and valve-type fittings, as you will notice in our catalog, are all designed for pressure\nratings based on 125% of Schedule 40 plastic fittings as described in ASTM D2513.\nAll the valves as shown in our catalog have been used satisfactorily in gas distribution systems\nranging from 2 to 3 years.\nWe would appreciate clarification as soon as possible.\nVery truly yours,\nR.W.
