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 treatment.Untreated forgings are usually relatively low carbon steel parts for noncritical applications…

What is WPHY?

What  is WPHY? MSS SP 75 WPHY Pipe Fittings. … “WP” is the abbreviation for “wrought pipefitting” while “HY” stands for “high yield”. These WPHY pipe fittings can be furnished as long-radius elbows, 3R elbows, straight tees, reducing tees, caps and reducers.
