There are many processing methods for stainless steel seamless elbows. The following mainly talks about the common processing methods of stainless steel seamless elbows.
1. Rolling method: This method usually does not require a mandrel and is suitable for the inner round edge of thick-walled pipes. The core is placed inside the tube, and the outer circumference is pushed by rollers for round edge processing.
2. Stamping method: use a tapered core on the punching machine to expand the pipe end to the required size and shape.
3. Bulging method: There are two types, one is to put rubber in the tube, and compress it with a punch above to make the tube protrude; the other is hydraulic bulging, filling the middle of the tube with liquid, and the pressure of the liquid will bulge the tube into the desired shape. desired shape.
4. Bending forming method: There are three types, one is stretching method, the other is stamping method, and the other is roller method. There are 3-4 rollers, two fixed rollers and one adjustment roller, which are used to adjust the fixed roller distance. The finished pipe fittings are curved.
These are the processing methods of stainless steel seamless elbows. Stainless steel seamless elbows have good corrosion resistance and will not cause erosion, rust and wear. Stainless steel is now one of the materials with the highest strength among metal materials.
