Is there a requirement for the curvature during the bending process? We need to understand the processing requirements in advance during the production process, because the size of the curvature of the bending directly determines the performance of the later use. Therefore, in order to ensure the better performance of the bending, we need to understand the curvature of the bending. Next, let's take a look at the requirements for the curvature of the bending.

No need for pipe blank as raw material, which can save on pipe making equipment and mold costs, and can obtain elbows with any large diameter and relatively thin wall thickness. The bent pipe blank is made of flat or stretchable surfaces, making it easy to cut, ensure accuracy, and facilitate assembly and welding. The basic process of forming alloy large diameter elbows is to first weld a polygonal polygonal multi edged ring shell or a multi edged fan-shaped shell with closed ends, and then fill it with pressure medium.

Due to the above two reasons, the manufacturing cycle of bending pipes can be shortened, and production costs can be greatly reduced. Due to the lack of corresponding equipment, it is very suitable for on-site processing of large elbows.
