Hot push forming carbon steel elbow
Hot push elbow forming process is the use of elbow pushing machine, core die and heating device, so that the blank set on the mold under the push of the machine to move forward, in the movement is heated, expanded and bending forming process.
Hot push bend deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.
Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production, so it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of some specifications of stainless steel elbow.
The heating methods of the forming process include medium frequency or high frequency induction heating (heating ring can be multi-turn or single turn), flame heating and reflection furnace heating. The heating method adopted depends on the requirements of the forming products and the energy situation.
Stainless steel elbow butt welding elbow
The main difference between stainless steel elbow and carbon steel elbow is the difference of the material, which contains chemical composition will keep the surface of the elbow for a long time will not rust, will not be corroded.In the pipeline system, the elbow is a pipe fitting to change the direction of the pipeline.The
