Underwood\nArea Manager, Raychen Corporation\nRedman Plaza East\n2550 Walnut Hill Lane\nSuite 162\nDallas, TX 75229\nDear Mr. Underwood:\nIn your letter of September 28, 1973, you requested a letter stating the position of the Department of Transportation\nregarding the use of Raychem’s GRS method of sealing leaking bell and spigot joints on cast iron piping. The Office of\nPipeline Safety neither endorses proprietary products nor conducts tests to determine acceptability under Department\nof Transportation standards. Our regulations, which are written in performance type language rather than detailed\nspecifications, prescribe the safety goal to be achieved while allowing the pipeline operator flexibility in choosing the\nbest methods to achieve this goal.\nBased on your meeting with Hessrs, Paul Cory and Lance Heverly of our staff, this product appears to be similar to others\nthat must be capable of providing the sealing characteristics of Section 192.753, Title 49 CFR; and it must meet the\nrequirements of Section 192.53 for materials for pipe and components. The gas operator must be able to demonstrate\nthat compliance has been proven by appropriate qualification test for the operating pressures and conditions\nanticipated. Such testing may be done by the operator, the manufacturer, or other interested parties.\nIf we may assist further in this matter, please let us know.\nSincerely,\nJoseph C. Caldwell\nDirector\nOffice of Pipeline Safety","truncated":false,"body_characters":1499}
