What type of pressure test can be used to assess pipeline integrity?
The integrity management rule requires that pressure tests be conducted according to the requirements of 49 CFR Part 192, Subpart J (192.921(a)(2), 192.937(c)(2)). This test uses a medium of liquid, air, natural gas, or inert gas to raise the pressure inside a pipe to a prescribed level for a prescribed length of time. (An operator must use test pressures specified in Table 3 of section 5 of ASME/ANSI B31.8S to justify an extended reassessment interval in accordance with 192.939. See FAQ 207). • FAQ-53. For operators having line pipe in states that have a pressure testing requirement, will satisfying the state requirement also suffice for satisfying the integrity assessment requirement of the integrity management rule? [05/17/2004]Answer: Any pressure test that meets or exceeds the requirements of Subpart J will satisfy the integrity management rule. • FAQ-55. A reduction in operating pressure can provide an equivalent level of safety as that provided by a Subpart J pressure test. Is a
