There are also many processing methods for
steel pipe fittings. Many also belong to the category of mechanical processing, and the most used are the stamping method, forging method, rolling method, rolling method, bulging method, stretching method, bending method, and combined processing method. Steel pipe fittings processing is an organic combination of machining and metal pressure processing.
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.
Stamping method: Use a tapered core on the punching machine to expand the end of the tube to the required size and shape.
Roller method: place a core in the tube, and push the outer circumference with a roller for round-edge processing.
Rolling method: Generally, no mandrel is used, and it is suitable for the inner round edge of thick-walled tubes.
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 familiar roller method. There are 3-4 rollers, two fixed rollers, and one adjustment Roller, adjust the fixed roller distance, and the finished steel pipe fittings are bent. This method is widely used, and the curvature can be increased if the spiral tube is produced.
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 tube is bulged into the required shape by liquid pressure, Most of the production of corrugated pipes we use is this method.
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 caps, etc., according to the connection method. It is 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. There are many ways to process them, among which:
1. Stainless steel pipe fittings can use the forging method, which can stretch a part of the pipe so that the outer diameter can be reduced.
2. The roller method can be used for stainless steel pipe fittings. A core can be placed inside the stainless steel pipe fittings, and a roller can be used to push the outside for round-edge processing.
3. The stamping method can be used for stainless steel pipe fittings, and the tapered core can be used to expand the pipe end to the desired size and shape on the punching machine.
