Stainless steel pipe fittings belong to a kind of pipe fittings. It is made of stainless steel, so it is called stainless steel pipe fittings. It includes stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel 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 with a wide range of uses. Generally speaking, the processing methods are as follows:
1. Forging method: use a swage forging machine to stretch the end or part of the pipe to reduce the outer diameter. Commonly used swage forging machines include rotary type, connecting rod type, and roller type.
2. Roller method: place a core in the stainless steel tube, and push the outside with a roller to process the round edge.
3. Stamping method: Use a tapered core on the punching machine to expand the pipe end to the desired size and shape.
4. Bending 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 method is the roller method. There are 3-4 rollers, two fixed rollers, and one adjustment roller. With a fixed roll gap, the finished pipe is bent.
5. Rolling method: Generally, no mandrel is used, and it is suitable for the inner round edge of thick-walled tubes.
6. Bulging method: one is to place rubber in the tube, and compress it with a punch above to make the tube protrude; the other method is hydraulic bulging, filling the middle of the tube with liquid, and the pressure of the liquid bulges the tube into the desired shape. Shape, most of the production of corrugated pipes uses this method.
