The difference between forged pipe fittings and cast pipe fittings

pipe fittings and cast pipe fittings

Generally speaking, the mechanical properties of castings are lower than those of forgings of the same material. In addition, the forging process can ensure the continuity of the metal fiber structure, keep the fiber structure of the forging consistent with the shape of the forging, and the metal flow line is complete, which can ensure that the parts have good mechanical properties and a long service life. The forgings produced by extrusion and warm extrusion are unmatched by castings.

After forging, the metal can improve its structure and mechanical properties. After the metal fiber structure is hot-worked and deformed by the forging method, due to the deformation and re-crystallization of the metal, the original coarse dendrites and columnar grains become fine-grained, uniform-sized equiaxed recrystallized structures, so that the original Segregation, loosening, porosity, slag inclusions, compaction and welding, the organization becomes tighter, improving the plasticity and mechanical properties of the metal.

Casting

The process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling and solidification and cleaning, a casting with a predetermined shape, size and performance is obtained.

Forging

A forging machine is used to apply pressure to the metal blank to cause plastic deformation to obtain a processing method of forgings with certain mechanical properties, certain shapes and sizes.
