Stainless steel pipe fittings are a kind of pipe fittings. They are made of stainless steel, 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., depending on the combination method. Divided into four categories: socket stainless steel pipe fittings, threaded stainless steel pipe fittings, flanged stainless steel pipe fittings and welded stainless steel pipe fittings. Stainless steel elbows are used for pipe turning places; flanges are used to make the pipe and pipe mutually continuous parts, which continue at the pipe end, stainless steel three-way pipes are used for three pipe collection places; stainless steel four-way pipes are used for four pipe collection places; stainless steel The reducing pipe is used in the place where two pipes of different diameters are combined.
1. Roller method: Place a core in the tube, and use a roller to push the outer circumference for round edge processing.
2. Forging method: Use a swage forging machine to punch out the end or one surface of the pipe to reduce the outer diameter. Common swage forging machines include twisting, connecting rod, and roller types.
3. Bending method: There are three methods commonly used, one method is called the stretch 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, one adjusting roller, and adjusting With a fixed roll distance, the finished pipe will be bent. Stainless steel pipe processing
4. Rolling method: Generally, no mandrel is used, and it is suitable for the inner round edge of thick-walled pipe.
5. Bulging method: one is to put rubber in the tube and compress it with a punch on the top to make the tube protrude into shape; the other method is hydraulic bulging, filling the middle of the tube with liquid, and the liquid pressure bulges the tube into the required This method is used in the manufacture of bellows.
6. Punching method: Use a tapered core on the punch to expand the pipe end to the required size and style.
