Basic process of ASME B16.9 Q235 Seamless Pipe Fitting 180deg Carbon Steel Elbow

　　The basic process of ASME B16.9 Q235 Seamless Pipe Fitting 180deg Carbon Steel Elbow is: first weld a polygonal ring shell with a polygonal cross-section or a polygonal fan-shaped shell with both ends closed. After the interior is filled with pressure medium, internal pressure is applied. Under the action of the internal pressure, the cross-section It gradually changes from a polygon to a circle, and finally becomes a circular ring shell. Depending on the needs, a circular ring shell can be cut into four 90-degree carbon steel elbows or six 60-degree carbon steel elbows or other specifications of elbows. This process is suitable for manufacturing any specifications where the ratio of the pitch diameter of the ASME B16.9 Q235 Seamless Pipe Fitting 180deg Carbon Steel Elbow to the inner diameter of the elbow is greater than ASME B16.9 Q235 Seamless Pipe Fitting 180deg Carbon Steel Elbows are currently the ideal method for making large carbon steel elbows.

　　The advantages of this carbon steel elbow manufacturing process are mainly reflected in the following aspects:

　　(1) No pipe blank is needed as raw material, which can save the cost of pipe making equipment and molds, and any ASME B16.9 Q235 Seamless Pipe Fitting 180deg Carbon Steel Elbow with large diameter and relatively thin wall thickness can be used.

　　(2) The blank is a flat plate or a developable curved surface, so the blanking is simple, the precision is easy, and the assembly and welding is convenient.

　　(3) Due to the above two reasons, the manufacturing cycle can be shortened and production costs reduced. Since it does not require any equipment, it is especially suitable for on-site processing of ASME B16.9 Q235 Seamless Pipe Fitting 180deg Carbon Steel Elbow.
