Characteristics of high press pipeline

　　High pressure forging pipe fittings are relative to casting pipe fittings. Forging machinery is used to exert pressure on the metal blank to produce plastic deformation, so as to obtain forgings with certain mechanical properties, certain shape and size.

　　The main process means of forging pipe fittings is forging, which means forging. By forging, the original coarse dendrite and columnar grain are transformed into equiaxed recrystallization structure with fine grain and uniform size, which makes the original segregation, porosity, porosity, slag inclusion and other compaction and welding in the ingot more compact, and improves the plastic and mechanical properties of the metal. The production of cast pipe fittings is mainly made of molds and models, which are processed by putting metal liquid into them, cooling, solidification and cleaning to obtain castings with predetermined shape, size and performance. High pressure forged pipe fittings mainly include high pressure forged flange, high pressure forged tee and other products.
