Description
A processing method that uses forging machinery toapply pressure to metal billets, causing them to undergoplastic deformation, in order to obtain forgings with certainmechanical properties, shape, and size.
By continuouslypounding the pipe fittings, the existing segregation, porosity, porosity, slag inclusion, etc. in the steel ingot are com-pacted and welded, resulting in a more compact microstructure and improved plasticity and mechanical properties ofthe metal.
Forged pipe fittings mainly include forged flangesforged reducers, forged tees, etc.
The main materials of forged pipe fittings include A105,40Cr,12Cr1MoV,30CrMo,15CrMo, etc.
Correspondingly to forged pipe fittings, the mechanical properties of castings are lower than those of forgings of the same material.
Cast pipe fittings melt metal into a liquid that meets certain requirements and pour it into the casting mold. After cooling, solidification, and cleaning treatment, the process of obtaining castings (parts or blanks) with predetermined shape,size,and performance.
