Establishing Fracture Mechanics Based on Minimum Allowable Temperatures for Low-Temperature Applications of ASME B31.3

Authors: Seetha Ramudu Kummari, Ph.D., P.E., Group Head, Senior Engineer II; and Kraig S. Shipley, P.E.

There are numerous risks with operating equipment at low temperatures, including brittle fracture. Although rare, the consequences of brittle fracture are typically catastrophic and preventing brittle fracture is essential when establishing fixed equipment lifecycle management strategies. This article discusses E2G’s proprietary Level 1 and Level 2 procedures for establishing minimum allowable temperatures (MAT) for low-temperature applications of ASME B31.3 piping, which is based on the state-of-the-art fracture mechanics methodology (WRC 562).
