Forged pipe fittings, which are made by forging. Forging involves using impact force to hammer the pieces.

The forging process involves applying pressure to metal billets using forging machinery to induce plastic deformation, resulting in forgings with specific mechanical properties, shape, and size. Through continuous hammering of pipe fittings, the original segregations, porosity, voids, and inclusions in the steel ingots are compacted and welded together, making the structure more dense and enhancing the metal's plasticity and mechanical properties. Forging pipe fittings primarily include forged flanges, forged reducers, and forged tees. The main materials for forged pipe fittings are Q235, Q345, 16Mn, 20#, 35#, 45#, 40Cr, 12Cr1MoV, 30CrMo, 15CrMo, and 20G. The corresponding process to forging pipe fittings is casting, where the metal is melted into a liquid that meets certain requirements and poured into a mold. After cooling, solidification, and finishing, castings (parts or blanks) with predetermined shape, size, and properties are obtained.
