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: the end or part of the pipe is punched out with a swaging machine to reduce the outer diameter. Common swaging machines include rotary type, connecting rod type, and roller type.
2. Roller method: Place the core of the stainless steel tube, and push it with a roller to process the edge.
3. Stamping method: Use a tapered core to expand the pipe end to the desired size and shape of the punching machine.
4. Bending forming method: There are three methods commonly used, one method is the stretching method, the other method is the stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, one adjustment roller, adjustment With a fixed roller pitch, the finished pipe is bent.
5. Rolling method: Generally no mandrel is needed, 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 protruding and forming; the other method is hydraulic bulging forming, filling the middle of the tube with liquid, and the pressure of the tube bulges the tube to the required shape, bellows production is mostly used in this method.
