No person may operate a new segment of pipeline, or return to service a segment of pipeline that has been relocated or replaced, until: [49 CFR 192.503(a)] 1. it has been tested in accordance with this Chapter and §2719 to substantiate the maximum allowable operating pressure; and [49 CFR 192.503","machine_formats":{"json":"https://regulus.evalyn.ai/document/la-lac-43-xiii-2303.json","markdown":"https://regulus.evalyn.ai/document/la-lac-43-xiii-2303.md"},"app_url":"https://regulus.evalyn.ai/document/la-lac-43-xiii-2303","source_url":"https://www.doa.la.gov/doa/osr/louisiana-administrative-code/","body":"A. No person may operate a new segment of pipeline, or return to service a segment of pipeline that has been relocated or replaced, until: [49 CFR 192.503(a)]\n\n1. it has been tested in accordance with this Chapter and §2719 to substantiate the maximum allowable operating pressure; and [49 CFR 192.503(a)(1)]\n\n2. each potentially hazardous leak has been located and eliminated. [49 CFR 192.503(a)(2)]\n\nB. The test medium must be liquid, air, natural gas, or inert gas that is: [49 CFR 192.503(b)]\n\n1. compatible with the material of which the pipeline is constructed; [49 CFR 192.503(b)(1)]\n\n2. relatively free of sedimentary materials; and [49 CFR 192.503(b)(2)]\n\n3. except for natural gas, nonflammable. [49 CFR 192.503(b)(3)]\n\nC. Except as provided in §2305.A, if air, natural gas, or inert gas is used as the test medium, the following maximum hoop stress limitations apply. [49 CFR 192.503(c)]\n\nClass Location\n\nMaximum Hoop Stress Allowed as Percentage of SMYS\n\nNatural Gas\n\nAir or Inert Gas\n\n1\n\n80\n\n80\n\n2\n\n30\n\n75\n\n3\n\n30\n\n50\n\n4\n\n30\n\n40\n\nD. Each joint used to tie in a test segment of pipeline is excepted from the specific test requirements of this Chapter, but each non-welded joint must be leak tested at not less than its operating pressure. [49 CFR 192.503(d)]\n\nE. If a component other than pipe is the only item being replaced or added to a pipeline, a strength test after installation is not required, if the manufacturer of component certifies that: [49 CFR 192.503(e)]\n\n1. the component was tested to at least the pressure required for the pipeline to which it is being added; [49 CFR 192.503(e)(1)]\n\n2. the component was manufactured under a quality control system that ensures that each item manufactured is at least equal in strength to a prototype and that the prototype was tested to at least the pressure required for the pipeline to which it is being added; or [49 CFR 192.503(e)(2)]\n\n3. the component carries a pressure rating established through applicable ASME/ANSI, Manufacturers Standardization Society of the Valve and Fittings Industry, Inc. (MSS) specifications, or by unit strength calculations as described in §1103.
