Hot push-formed elbow
Hot push elbow forming process is the use of elbow pushing machine production, mandrels and heating devices, is set on the mold of the pipe billet in the elbow pushing machine to push forward, in the movement is heated and expanded diameter 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 expanding, resulting in wall thickness of the elbow.
Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and connection operation, suitable for mass production, so it has become the main forming method of carbon steel and alloy steel elbow. If it is stainless steel elbow, cold push elbow machine will be selected for forming.
The heating method of forming process has medium frequency or high frequency induction heating, high frequency is generally used in the small elbow within 114, medium frequency is generally used in the large elbow above 114.
Long radius seamless elbow
The long radius seamless elbow is one of the metal fittings used to change the direction of a carbon steel pipe.The connection mode is generally mainly used for welding.According to the Angle divided into 45 degrees and 90 degrees 180 degrees three commonly used, in addition to 60 degrees and other abnormal Angle elbow according to the needs of the project.
Elbow materials are cast iron, stainless
