Forged pipe fittings, which are made by forging methods. Forging involves the creation of parts through the application of impact force.

A method of processing forgings with certain mechanical properties, shape, and size by applying pressure to metal billets using forging machinery, causing plastic deformation. Through continuous hammering of pipe fittings, the original segregation, porosity, gas holes, inclusions, etc., within the ingot are compacted and welded together, resulting in a tighter structure and improved plasticity and mechanical properties of the metal. Forging pipe fittings mainly include forged flanges, forged reducers, and forged tees. The main materials for forging pipe fittings are Q235, Q345, 16Mn, 20#, 35#, 45#, 40Cr, 12Cr1MoV, 30CrMo, 15CrMo, 20G, etc. Corresponding to forged pipe fittings are cast pipe fittings, where the mechanical properties of castings are lower than those of forgings made from the same material. The casting process involves melting the metal into a liquid that meets certain requirements, pouring it into a mold, and then cooling, solidifying, and finishing it to obtain castings (parts or blanks) with predetermined shape, size, and properties.
