LAC 33:V.30165. External Loads [49 CFR 195.110]

A. Anticipated external loads (e.g., earthquakes, vibration, thermal expansion, and contraction) must be provided for in designing a pipeline system. In providing for expansion and flexibility, Section 419 of ASME must be followed. [49 CFR 195.110(a)] B. The pipe and other components must be supported in such a way that the support does not cause excess localized stresses. In designing attachments to pipe, the added stress to the wall of the pipe must be computed and compensated for. [49 CFR 195.110(b)]
