Hebei carbon steel seamless elbow
Carbon steel seamless elbow is a common use of elbow material, cheap, easy to use.
According to the material: low carbon steel, medium carbon steel, high carbon steel, steel no. 20, etc., characterized by relatively high carbon content.According to the standard is divided into: GB, non-GB, GB: German standard, Japanese standard, American standard, British standard elbow.The raw material of carbon steel seamless elbow is seamless steel tube. The main production process is round billet -- heating -- perforating -- three bar cross rolling, continuous rolling or extrusion -- tube management -- sizing -- cooling -- straightening -- hydrostatic test or flaw detection -- marking -- storage.
Hebei elbow plant has good comprehensive performance, so it is widely used in chemical engineering, construction, petroleum, drainage, plumbing, fire protection, electricity and other basic projects.
The elbow made by cold extrusion process of inner and outer die is beautiful in appearance, uniform in wall thickness and small in size deviation, so it is manufactured by this process for stainless steel elbow forming, especially for stainless steel elbow on thin wall.The precision of the inner and outer die used in this process is high, and the deviation of the wall thickness of the tube billet is also demanding.
Hebei elbow factory is divided into cold stamping and hot stamping, usually according to the nature of the material and equipment capacity to choose cold stamping or hot stamping.Cold extrusion elbow molding process is the use of elbow molding machine, the tube billet into the outer die, the upper and lower die closing, in the push rod morning, the tube billet along the inner membrane and the outer die clearance operation and complete the forming process.
