Classification of fittings by use and material

Butt welding barrel nipple
Pipe fittings are a general term for the components in the pipeline system that play the roles of connection, control, direction change, flow splitting, sealing, and support. Steel fittings are pressure-bearing fittings. According to the different processing technology, it is divided into four categories, namely butt welding pipe fittings (divided into welded and non-welded pipe fittings),
