We have professional technical strength and advanced team management capabilities. Grades include: 304.304L.304H.321.321H.316.316L.317L.310S.347H, etc. Pipe size range (6mm-580mm) * outer diameter (2mm-40mm) WT * 4000-15000mm) length.
There are many processing methods for stainless steel seamless elbows, so what are the main ones? Listen to Licheng’s introduction below.
①[Stamping method]: Stamping uses a tapered core on a punch to expand the pipe end to the required size and shape.
②[Rolling method]: Rolling usually does not require a mandrel. It is suitable for the inner round edge of thick-walled pipes. The core is placed inside the pipe and the outer periphery is pushed with rollers. Used for round edge processing.
③[Bulging method]: There are two methods of bulging: one is to put rubber in the tube and compress it with a punch above to make the tube bulge; the other is hydraulic bulging, in which liquid is filled in the middle of the tube, and the liquid pressure will The tube is bulged into the desired shape.
④[Bending forming]: There are three methods of bending forming: one is the stretching method; one is the stamping method; one is the roller method, which has 3-4 rollers, 2 fixed rollers, and 1 adjusting roller. Adjust the fixed roller distance, and the finished pipe will be curved.
So the common processing methods for stainless steel seamless elbows are mainly these.

What issues should be paid attention to when surface treatment of stainless steel seamless elbow?
Who can tell me why cracks occur on the surface of stainless steel seamless elbows?
