Stainless steel pipe fittings are a kind of pipe fittings, which 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 caps and so on. According to the continuous method, it can be divided into socket stainless steel pipe joints, pipe joint ribs, stainless steel joints, flange stainless steel joints and welded stainless steel joints.
Stainless steel joints are a new type of pipe fittings with a relatively wide range of functions. For ordinary enterprises, the processing technology skills are similar to the following:
1. Casting skills: use a die forging machine to punch or stretch the end or one side of the tube to reduce the outer diameter.
2. Roller skills: Place the core in the stainless steel Yonghua hydraulic pipe, push with rollers, and process the round edge.
3. Punching technique: Use the tapered core on the punch to expand the tube end to the required size and style.
4. Winding forming method: There are three methods and techniques that are commonly used in systematic research, one technique is called stretching method, another technique is called stamping method, and the third method is roller method. There are 3-4 rollers and two fixed rollers. One adjusting roller, adjusting the fixed roller pitch, the finished pipe will pass through meandering.
5. Rolling method: Ordinary Yonghua transition metal joint mandrel is suitable for the inner round edge of thick-walled pipe.
6. Bulging method: One technique is to put the rubber into the tube and compress it with a punch to bulge the tube; the other technique is hydraulic bulging, that is, the center of the tube is filled with liquid, and the liquid pressure causes the tube to expand to the required pattern. , Most of the bellows are produced in this way.
