Views: 0    

Stainless steel pipe fittings are a type of pipe fittings. They are made of stainless steel materials, so they are called stainless steel pipe fittings. They include stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel pipe caps, etc., according to the connection method It 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 swaging machine to punch the end or part of the pipe to reduce the outer diameter. Commonly used swaging machines include rotary, connecting rod, and roller types.
2. Roller method: Place the core inside the stainless steel tube, and push it with a roller on the outside to process the round edge.
3. Stamping method: Use a tapered core on a punch to expand the pipe end to the desired size and shape.
4. Bending forming method: There are three commonly used methods, one method is called the stretching method, the other method is called the stamping method, and the third roller method has 3-4 rollers, two fixed rollers, and an adjusting roller. With a fixed roller distance, the finished pipe is curved.
5. Rolling method: Generally, no mandrel is used, and it is suitable for the inner round edge of thick-walled pipes.
6. Bulging method: One is to place rubber inside the tube, and use a punch to compress it above to make the tube bulge into shape; the other method is hydraulic bulging, in which liquid is filled into the middle of the tube, and the liquid pressure bulges the tube into the required shape. Shape, corrugated pipes are mostly produced using this method.
