Difference between forged pipe fittings and cast pipe fittings

  Forged pipe fittings are made by forging. Forging is made by forging with 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 pipe fittings 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 pipe fittings 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 pipe fittings 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.
