Williams\nPhillips Driscopipe, Inc.\n2929 North Central Expressway\nSuite 100\nRichardson, TX 75083\nDear Mr. Williams:\nI am responding to your letter of June 10, 1991, addressed to Richard Sanders at the\nTransportation Safety Institute. You asked what qualifications shop fabricated mitered\npolyethylene fittings must meet for use in gas distribution systems. In addition, you asked who\nmust qualify the procedures for joining plastic pipe of different manufacturers.\nPlastic fittings used in gas distribution systems are subject to the Federal pipeline safety standards\nin 49 CFR Part 192. They also must meet any additional or more stringent safety standards that\nmay be in effect under the law of the state in which the fittings are to be installed. Under Part\n192, a shop fabricated mitered polyethylene fitting qualifies for use in a gas distribution system if\nit satisfies the general materials and design requirements of §§192.143 respectively, and conforms\nto ASTM D2513 as provided by §192.191.\nSection 192.283 requires pipeline operators to use a qualified procedure in joining plastic pipe of\ndifferent manufacturers. The section does not specify who must qualify the procedures.\nQualification may be done by anyone, including the operator, either manufacturer, or both\nmanufactures. If the operator uses a joining procedure qualified by others, it is still responsible\nfor compliance with the Part 192 qualification requirements. To fulfill this obligation, it must\nassure itself that the procedures have been properly qualified under those requirements.\nI apologize for the delay in answering your letter. However, please don't hesitate to write again if\nyou need any more information regarding the Department's pipeline safety standards. A copy of\nPart 192 is enclosed.\nSincerely,\nCesar DeLeon\nDirector For Pipeline Safety\nRegulatory Programs\nDB\nC:\\WP51\\INTERPRT\\192\\191\\91-10-07\n1","truncated":false,"body_characters":1917}
