Six processing methods of stainless steel pipe fittings

　　Stainless steel pipe fittings are a type of pipe fittings. They are made of stainless steel material, hence the name stainless steel fittings. Including stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel pipe caps, etc.

　　According to the connection method, they can be divided into four categories: socket stainless steel pipe fittings, threaded stainless steel pipe fittings, flange stainless steel pipe fittings and welded stainless steel pipe fittings.Stainless steel pipe fittings are a new type of pipe fittings that are widely used. Generally speaking, the processing methods are as follows:

　　1. Forging method: Use a forging press to punch the end or part of the pipe to reduce the outer diameter. Commonly used rotary forging machines include rotary, connecting rod and roller types.

　　2. Roller method: Put the core into the stainless steel tube and push it with a roller on the outside to process the round edge.

　　3. Stamping method: Use the tapered core on the punch to expand the pipe end to the required size and shape.

　　4. Bending forming method: There are three commonly used methods, one method is called stretching method, the other method is called stamping method, and the third roller method has 3-4 rollers, two fixed rollers and one adjusting roller. . At a fixed roller distance, the finished pipe is bent.

　　5. Rolling method: Generally, mandrels are not used and are suitable for inner round edges of thick-walled tubes.

　　6. Bulging method: One is to put rubber in the pipe and press it with a punch to make the pipe bulge; the other method is hydraulic bulging, which is to fill the middle of the pipe with liquid and use the liquid pressure to bulge the pipe. Expanded into desired shape. Special-shaped and corrugated pipes are mostly produced using this method.
