Archived Rulemaking: Transportation of Natural and Other Gas by Pipeline; Design of Pipeline Components, General Requirements

48-50908.pdf (412.23 KB)

This notice proposes to revise the general requirements for design of pipeline components to recognize that limiting stresses to "unit stresses equivalent to those allowed for comparable material in pipe in the same location and kind of service" is not an appropriate criterion, from a safety standpoint, for many pipeline components. In response to a petition from the American Society of Mechanical Engineers, the Materials Transportation Bureau proposes to clarify the requirements.
