You ask whether Section 195.308 requires that pipe at tie-ins be hydrostatically\ntested if a carrier has a manufacturer's certification for the pipe in accordance with Section 195.304.\nAs a general requirement under Section 195.302, each pipeline system or part thereof which is\ninstalled, relocated, or replaced must be hydrostatically tested by the carrier. The purpose of Section\n195.308 is to provide that in hydrostatically testing pipe associated with tie-ins in a pipeline system, the\ntest may be made either with the section to be tied in or separately.\nThe exception from the general requirement under Section 195.304, where the manufacturer of a\ncomponent makes a certification regarding hydrostatic testing at the factory, does not apply to pipe.\nWhile Section 195.2 includes the term \"pipe\" within the definition of the term \"component,\" the two\nterms are used distinctly in Section 195.304 to provide that only components other than pipe need not\nbe hydrostatically tested.\nUnder this interpretation, a hydrostatic test performed on pipe at the factory would not meet the\nrequirements of Section 195.302 and 195.308 that pipe at tie-ins be hydrostatically tested by the carrier\nfor at least 24 hours either with the section to be tied in or separately.\nCesar DeLeon, MTP-1\nDB/dal/195.308\n75-08-18\n1","truncated":false,"body_characters":1631}
