heat treatment of fittings or flanges

Heat treatment of pipe fittings or flanges

Heat-treatment of fittings or  flanges Heat treatment is thermal cycling involving one or more reheating and cooling after forging the purpose of obtaining desired microstructure and mechanical properties in a forging. Few forgings of the types are produced without some form of heat enclosures. Untreated forgings are usually relatively low carbon steel parts for noncritical…
