Wenzhou Licheng Steel Industry Co., Ltd. is a modern enterprise specializing in stainless steel pipes, pipe fittings and flange products. We have professional technical strength and advanced team management capabilities. Grades include: 304.304L.304H.321.321H.316.316L.317L.310S.347H and other pipe size range (6mm-580mm)*outer diameter (2mm-40mm)WT*4000-15000mm) length.
The common forming process of stainless steel seamless elbow is push bending, which is to bend the steel pipe.
The push forming process can be divided into cold push bending and mandrel hot push bending.
Cold push bend:
Use a bending device to push the bent tube blank on a common hydraulic press or crank press, and put the stainless steel tube into a mold with a bending cavity at room temperature to form a stainless steel seamless elbow.
Mandrel hot push bending:
The mandrel-type hot-bending pipe is used in the pushing machine. Under the axial thrust, it passes through the horn mandrel, and pushes it while heating, so that the tube blank produces axial expansion and axial bending deformation, so that the smaller diameter pipe Push to make larger diameter elbows.
