RMC-06-86 Understanding Weld Failures in Refinery Equipment

Description:

Welding has been used to construct much of the equipment in refineries. This includes piping, pressure vessels, structures, instruments, pumps, valves, etc. Welding is so widely utilized and relied upon because weld properties (strength, ductility, corrosion resistance, etc.) usually function as well as the metals they join. However, welds, like other joining methods also represent anomalies in the fabricated components. Sometimes these anomalies initiate failures. This presentation will review causes for weld failures and discuss what precautions should be taken to prevent them.
