What are the commonly used forming methods for stainless steel seamless elbows?
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 commonly used forming methods of stainless steel seamless elbows are forging method, rolling method, stamping method, bulging method and bending forming method. Licheng Steel Industry will introduce it for you below.
1. Forging: refers to using a swage forging machine to stretch the end or part of the pipe fittings to reduce the outer diameter. Commonly used swage forging machines are rotary, connecting rod and roller.
2. Rolling: refers to placing a core in the tube, and pushing the outer circumference with a roller for round edge processing. Generally, no mandrel is used, and it is suitable for the inner round edge of thick-walled pipes.
3. Stamping: refers to expanding the pipe end to the required size and shape with a tapered core on the punching machine.
4. Bulging: There are two methods: ① Place rubber in the tube, and compress it with a punch above to make the tube protrude. ②Hydraulic bulging forming: fill the tube with liquid, and the pressure of the liquid will bulge the tube into the desired shape. This method is mostly used in bellows production.
5. Bending forming: There are three methods: ① Stretching method; ② Stamping method; ③ Roller method, there are 3-4 rollers, 2 fixed rollers, and 1 adjusting roller for adjusting the roller distance, and the pipe is bent after completion.
