  Forged steel socket pipe fittings elbows are made by forging. Forging is a piece forged by impact force.

  The forging machine is used to exert pressure on the metal blank to produce plastic deformation, so as to obtain the forging with certain mechanical properties, certain shape and size. By hammering the forged steel socket pipe fittings elbow continuously, the original segregation, porosity, porosity and slag inclusion in the ingot are compacted and welded, the structure becomes closer, and the plasticity and mechanical properties of the metal are improved. Forged steel socket pipe fittings elbow mainly include forged flange, forged reducer, forged tee, etc. Forged pipe fittings are mainly made of Q235, Q345, 16Mn, 20 #, 35 #, 45 #, 40Cr, 12Cr1MoV, 30CrMo, 15CrMo, 20g, etc.

  Corresponding to the forged steel socket pipe fittings elbow are cast pipe fittings. The mechanical properties of castings are lower than those of forgings of the same material. The cast pipe fittings melt the metal into a liquid meeting certain requirements and pour it into the mold. After cooling, solidification and cleaning, the castings with predetermined shape, size and properties are obtained.
