Six processing methods of stainless steel pipe fittings

Stainless steel pipe fittings are 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 tees, stainless steel reducers, and stainless steel pipe caps. According to the connection method Can be divided into 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: The end or part of the pipe is extruded with a forging machine to reduce the outer diameter. Common forging machines are rotary, link and roller.

2. Roller method: Place the core in the stainless steel tube, and use the roller to push the outside to process the round edge.

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

4. bending forming method: There are three methods more commonly used, one method is called the stretching method, the other method is called the stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, one adjustment roller, adjustment With fixed roller pitch, the finished pipe is bent.

5. Rolling method: Generally, no mandrel is used, which is suitable for the inner round edge of thick-walled pipes.

6. Bulging method: one is to place rubber in the tube, and compress with a punch above to make the tube protrude into shape; the other method is to use hydraulic inflation to form a liquid in the middle of the tube, and the pressure of the liquid to swell the tube into the required This method is mostly used in the production of shapes and bellows.
