Production process of high press forged pipe fitting half coupling

The main technological means for High press Forged Pipe Fitting Half Coupling are forging. Forging is meant to be forged. By forging, the original coarse dendrites and columnar grains are changed into recrystallized structures with fine grain size and uniform size, so that the original segregation, porosity, porosity and slag inclusion in the ingot are compacted and welded, and the microstructure becomes more compact and improved. The plastic and mechanical properties of the metal. The pipe fitting half coupling is made mainly by mold and model, by putting metal liquid into it, after cooling, solidifying and finishing, the pipe fitting half coupling is made by the castings with predetermined shape, size and performance. High-pressure forging pipe fitting half coupling are mainly high-pressure forging flange and high-pressure forging tee and other products.

　　There are different forging processes, of which the hot die forging process is the longest. The general order is: forging blank blanking; forging billet heating; roll forging blank preparation; die forging forming; cutting edge and a series of production processes.
