Stainless steel seamless elbow is a high-strength material used in the construction industry. It has good corrosion resistance and allows structural components to maintain engineering design integrity.
The following is an introduction to five forming methods of stainless steel seamless elbows.
① Forging method: Use a forging machine to punch the pipe end or part to reduce the outer diameter.
②Rolling method: Generally, a mandrel is not used, and it is suitable for the inner round edge of thick-walled tubes; a core is placed inside the tube, and the outer periphery is pushed with a roller for round edge processing.
③ Stamping method: Use a tapered core on a punch to expand the pipe end to the required size and shape.
④Bending forming method: divided into stretching method, stamping method and roller method.
⑤ Bulging method: One is to put rubber inside the tube and compress it with a punch to make the tube bulge into shape. One is hydraulic bulge forming, in which liquid is filled into the middle of the tube. A mule
