Elbow pipe fittings manufacturers commonly used raw materials
Elbow manufacturers commonly used materials are mainly divided into carbon steel, alloy steel, stainless steel and so on. Carbon steel commonly used models are mainly divided into Q235, 20#, A105, etc., stainless steel is mainly divided into: 304, 304L, 316, 316L, 321, 00Cr17Ni14Mo2, etc.. Alloy steel materials are mainly divided into: 15CrMo, 1Cr5Mo, 16Mn, 12Cr1MoV, F11, F22, 10CrMo910, etc. The above materials are mainly processed according to the model and wall thickness of the material required by customers.
Bend manufacturers in the production process of advanced production technology and equipment processing into customer needs.
Pipe fittings produced by bend head manufacturers are mainly pipe connectors used in main pipe branches. Direct welding or flange connection is commonly used in connection.
The Angle of elbow manufacturer is divided into: 45 degrees, 90 degrees, 180 degrees and other different types of Angle.
The manufacturing process of carbon steel elbow pipe fittings is mainly divided into the following points:
Pushed the forming, hot push bend forming process is to use common elbow push rod core machine, mould and heating device, make the mould of billet in heating of driven push press forward, expansion and bending motion process, the deformation characteristic of hot pushing elbow is according to the law of constant volume in metal plastic deformation before and after the determine the pipe diameter, pipe diameter is less than the bent pipe diameter. The deformation process of the billet is controlled by the core mold, so that the metal flow in the inner arc compensates for the expansion and thinning of the diameter of the other parts, so that the uniform wall thickness of the elbow is obtained.
Hot push elbow forming process has uniform wall thickness, beautiful appearance, continuous operation, suitable for mass production, has become the main forming method of carbon steel and alloy steel elbow, also suitable for some specifications of stainless steel elbow forming.
The heating mode of forming process is medium frequency or high frequency induction heating (heating ring can be multiple or single circle), flame heating and reflector heating. Heating mode is determined according to the requirements of molding products.
