Pipe Fittings plays a role in the connection, control, change of direction, streaming components collectively sealed and supporting. Carbon steel pipe fittings is currently the most widely used one pipe products. The main material q235, 20 #, 35 #, 45 #, 16mn main. The main products include carbon steel elbow, carbon steel flanges, carbon steel tee, carbon steel, four-way, carbon steel pipe reducer (size of the head), carbon steel head (cap). Mainly the implementation of standards, including the national standard, American standard, Japanese standard.

Steel fittings are called pressure pipe fittings. Depending on the processing technology, divided into three categories, namely butt class fittings (weld and weld two), socket welding and threaded pipe fittings, flanges and fittings.

Tube joints of the piping system, the shape of different sizes, to connect to a straight tube or a tube section. Any pipe after deep processing products should belong to the scope of pipe fittings, this product has the dual characteristics of the tube and mechanical parts.

Side are the use of paint as the fittings or oxidation-resistant metal (e.g., zinc, nickel and chromium) electroplating to be guaranteed. But, as everyone knows, tube in the outer layer is just a thin film. Once the protective layer is damaged, the following steel began to rust. Preservative are generally of the tube member depends on the zinc, nickel and chromium, but also belong to one of the part of the steel due to zinc, nickel and chromium, so protect methods vary.
