ASME B16.5-2007 Flange Refacing

The process of flange facing or flange refacing involves the machining of flange mating surfaces so that they produce a tight, leak-proof seal when assembled.

The American Society of Mechanical Engineers (ASME) are the go-to organisation for many standards for mechanical engineering around the world. ASME set the standards for flange face surface finish types through the ANSI accredited ASME Standard B 16.5 ensuring all gasket and flange fittings are consistent and fit for purpose allowing a high quality seal.
