Pipe Fittings manufacturer Description Of DIN M Pipe Fittings Pipe fitting is a general term for the parts and components that play the role of connection, control, redirection, diversion, sealing, and support in the pipeline system. DIN M pipe fittings have a wide range of applications. The manufacturing process mainly adopts hot-rolled longitudinal seam welding, spiral double-sided submerged arc welding, forging, forging, intermediate frequency pushing, cold forming, hot extrusion, etc. The maximum processing diameter of the pipe is 2020 mm. DIN M pipe fittings are widely used in engineering fields such as municipal administration, petrochemical industry, west-to-east gas transmission, shipbuilding and nuclear power. There are many types of pipe fittings, which are classified according to use, connection, material, and processing methods. Classified by purpose: 1. The pipe fittings used to connect the pipes are: flanges, unions, pipe clamps, clamps, ferrules, hose clamps, etc. 2. Fittings that change the direction of the pipe: elbows, elbows. 3. Fittings for changing the pipe diameter: reducing diameter (reducing pipe), reducing elbow, branch pipe stand, reinforcing pipe. http://www.kn-tubes.com/pipe-fittings/
