P. Petro\nDirector Technical Services\n3240 North Mannheim Road\nFranklin Park, Mob 60131\nDear Mr. Petro:\nThis responds to your letter of July 6, 1979, asking if the rule in 49 CFR 192.281(a), stating that\n\"plastic pipe may not be Joined by a threaded joint or miter Joint,\" applies to the manufacture of\nfittings in a plant.\nAs indicated by Section 192.271(b), neither section 192.281 nor any of the other provisions of\nSubpart F concerning the joining of materials apply to Joining that is performed during the\nmanufacture of pipe or components (including fittings). The regulations do apply to any Joining of\npipe or components that occurs for gas pipeline transportation purposes outside the manufacturing\nfactory. Such joining is normally performed at a pipeline construction site or in fabrication shops.\nSincerely,\nSIGNED\nCat& De Leon\nAssociate Director for\nPipeline Safety Regulation\nMaterials Transportation Bureau\n\n<<<PAGE 3>>>\n\nKerotest manufacturing Corp\n2525 Liberty Avenue\nPittsburgh, PA 15222\nJune 9, 1983\nU. S. Department of Transportation\nResearch and Special Programs Administration\n100 Seventh Street - S.W.\nWashington, D.C. 20590\nGentlemen:\nWe are requesting an interpretation on Paragraph 192.281(a) in the Code of Federal\nRegulations. This paragraph states in part, \"Plastic pipe may not be joined by a threaded joint.\"\nDoes the scope of this requirement include threaded joints integral to the design of plastic valves\nand fittings or is its jurisdiction limited to restricting the use of threaded joints between plastic pipe\nand other components?\nThe answer to the above question will have an immediate impact on our line of thought for\nfuture products. It is requested that you expedite your answer and forward them to us as soon as\npossible.\nThanking you in advance for your time and effort.\nSincerely yours,\nEdward L.
