Various Processing Methods Of Stainless Steel Tube Fittings

There are also many ways to process stainless steel tube fittings. Many of them still belong to the category of mechanical processing, using stamping, forging, roller processing, rolling, bulging, stretching, bending, and combined processing. Tube fitting processing is an organic combination of machining and metal pressure processing.

Here are some examples: 

Forging method: Use a swaging machine to stretch the end or part of the pipe to reduce the outer diameter. Commonly used swaging machines include rotary, connecting rod, and roller types.

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

Roller method: Place a core inside the tube and push the outer circumference with a roller for round edge processing.

Rolling method: generally does not require a mandrel and is suitable for the inner round edge of thick-walled pipes.

Bending forming method: There are three commonly used methods, one method is called stretching method, the other method is called stamping method, and the third method is the more familiar roller method, which has 3-4 rollers, two fixed rollers, and one adjusting roller. Roller, adjust the fixed roller distance, and the finished pipe fitting will be curved. This method is widely used. If spiral tubes are produced, the curvature can be increased.

Bulging method: one is to place rubber inside the tube and compress it with a punch above to make the tube bulge into shape; the other method is hydraulic bulging, in which liquid is filled into the middle of the tube and the tube is bulged into the required shape by the liquid pressure , most of our commonly used corrugated pipes are produced using this method.

In short, pipe fittings are widely used and come in many types.
