Easy to operate elbow use and fabrication methods

The use of carbon steel elbow pipe products can make the pipe installation do a variety of different angles of turning, steel pipe in different angles, let people in the use of steel pipe without recognition of the problem, the following to introduce the production method of carbon steel elbow:

The use of hot push forming process is the selection of common elbow push machine, mandrel and heating equipment, is the blank set in the mold in the push machine to move forward, in the movement is heated, expanding and zigzag forming process. The deformation characteristic of hot pushing elbow is to determine the diameter of the tube billet according to the rule of constant volume before and after plastic deformation of metal materials, the diameter of the tube billet is less than the diameter of the elbow, after the core rod operation control of the deformation process of the blank, is the metal activity of the inner arc is compressed, compensated to the other parts thinned due to the expansion of the diameter, and then get the elbow with uniform wall thickness, hot pushing elbow forming process has a beautiful shape. Uniform wall thickness and continuous operation, suitable for the characteristics of mass production, thus becoming the first forming method of carbon steel, alloy steel, and also used in some standard stainless steel elbow forming, forming process heating method has medium frequency or high frequency induction heating and heating coil, flame heating and reflectivity furnace heating, choose the heating method forming product requirements and energy situation resolution. The above briefly introduces the hot push forming process of carbon steel elbow.

Elbows in pipe fittings are mainly used to change the direction of pipe fittings. Elbow according to the Angle, there are 45° and 90°180° three commonly used, in addition, according to the needs of the project also includes 60° and other abnormal Angle elbow.
