Metleader supplies real seamless 180° carbon steel elbow and seam 180° carbon steel.In strict accordance with the ISO 2008 international Quality Management system certification for production, and strict product quality management model to promote scientific management. My company's carbon steel elbow and other carbon steel pipe parts in the market share is steadily improving, we produce products with steel pipe connection, the use of transport media, in the country unanimously supported and recognized.
Seamless 180° carbon steel elbow is made of pipe bending, can be welded, so called welded elbow, not that it has its own weld, in fact, the opposite, welded elbow due to the use of straight pipe stamping bending, taking into account the structural stress of the general use of seamless pipe. Rather than welded tubes. , and the so-called seamless elbow is castings, not welded. In the pipe system used in all the pipe fittings, Seamless 180° carbon steel elbow, the proportion of large, about 80%. In general, different forming processes are selected for different material or wall thickness elbows. Factory commonly used seamless elbow forming process has hot push, stamping, extrusion and so on.
Seamless elbow pipe Because of its different manufacturing process, but also divided into hot-rolled (extrusion) seamless elbow pipe fittings and drawing (rolling) seamless elbow pipe two. Drawing (rolling) tube is divided into circular tubes and special-shaped tubes. The raw material of seamless elbow pipe is round tube billet, the tube embryo is cut by cutting machine and processed into a billet of about one meter in length, and is sent to the furnace by conveyor belt. The billet is heated in a furnace, at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Temperature control in the furnace is a key problem. After the Tube billet is released, it must be worn by a pressure piercing hole. Generally more common punch is the cone-shaped roller piercing machine, this type of piercing machine production efficiency, product quality, perforation expansion is large, can wear a variety of pipe fittings. After perforation, the round tube billet has been three-roll skew rolling, continuous rolling or extrusion. After extrusion to remove the tube sizing. The sizing machine rotates into the steel embryo punch through the conical bit at high speed to form a pipe fitting.
What is 90° carbon steel elbow ? Bending angle of 90 degrees of elbow, and other seamless carbon steel elbow process is the same.
