Nowadays
malleable steel pipe fittings are widely used in many industries, such as fire industry, where pipes are connected by malleable iron pipe fittings, because malleable iron pipe fittings can avoid being damaged by fire.
The malleable iron we refer to is actually cast iron, malleable iron, which is obtained by heat treatment after molten iron casting. Therefore, pipe fittings of different shapes and specifications are actually produced by mold casting, and different pipe fittings are produced by different molds.
Malleable iron pipe fittings go through heat treatment from the blank, and then go to flat mouth shaping and derusting, and then go through galvanizing treatment, and then die, and rust prevention, and finally they are packaged out of the factory.
This series of processes produced malleable iron pipe fittings.
