High-pressure elbow manufacturing process

- Nov 27, 2020-

                                   The manufacturing process of the high-pressure elbow firstly welds a polygonal ring shell with a polygonal cross section or a multi-edge fan shell closed at both ends. After the internal pressure is filled with the pressure medium, the internal pressure is applied, and the cross section changes gradually from the polygon under the action of the internal pressure. Rounding, eventually becoming a circular ring shell. As needed, a circular ring shell can be cut into four 90 elbows or six 60 high-pressure elbows or other high-pressure elbows. This process is suitable for manufacturing high-pressure elbows. Any large elbow with a medium diameter and a stamped elbow with an internal diameter ratio greater than 1.5 is an ideal method for manufacturing large national standard elbows. 

  High pressure elbows are suitable for pipeline systems in the petroleum, natural gas, chemical, hydropower, construction and boiler industries. Without the need for tube blanks as raw materials, the cost of pipe making equipment and molds can be saved, and the national standard elbows with any large diameter and relatively thin wall thickness can be obtained. Due to the above two reasons, the manufacturing cycle can be shortened and the production cost is greatly reduced. It does not need any special equipment, especially suitable for on-site processing of large national standard elbows. The blank is flat or expandable surface, so the material is simple to cut, the precision is easy to guarantee, and the assembly and welding are convenient.
