National standard seamless elbow manufacturers have a lot of concessions
The company mainly produces various types of seamless elbow pipe fittings, the material of seamless elbow pipe fittings is mainly divided into carbon steel, alloy steel, stainless steel and so on. Seamless elbow pipe fittings complete products, many styles, primary supply, more preferential advantages.
Seamless elbow pipe fittings produced by manufacturers are also known as seamless steel pipe fittings, seamless elbow pipe fittings due to different manufacturing processes, and divided into hot rolled extrusion seamless elbow pipe fittings and cold drawn seamless elbow pipe fittings. Cold drawn or cold rolled pipe is divided into round pipe and shaped pipe two.
The raw material for rolling seamless elbow pipe fittings is a round tube billet, which is cut and processed into billets with a length of about one meter. The billet is then sent through a conveyor belt to a furnace where the billet is heated at a temperature of about 1200 degrees Celsius. The fuel is hydrogen. The temperature control in the furnace is the problem of pipe fitting. General more common puncher is the cone roll puncher, this kind of puncher has high production efficiency, good product quality, large perforation and diameter expansion, can wear a variety of pipe, after perforation, round tube billet has been three rolls diagonal rolling, rolling or extrusion, extrusion to take off pipe sizing.
Seamless elbow production process is divided into: forging method, rolling method, stamping method. Seamless elbow pipe fittings in the use of the main advantages of corrosion resistance, light weight, good internal heat or long service life.
The service life of seamless elbow: the service life of the pipe can reach more than 50 year
