Six Main Methods for Bending Pipe Processing

There are six main methods for Bending pipe processing. Now let me introduce them in detail. The commonly used methods for Bending pipe processing are:

1. Bulging method: One method is to place rubber inside the tube and compress it with a punch to make the tube protrude and form; Another method is hydraulic bulging forming, which fills the middle of the pipe with liquid and the liquid pressure bulges the pipe into the desired shape. This method is mostly used in the production of corrugated pipes

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

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

4. Rolling method: Generally, there is no need for a mandrel, which is suitable for the inner circular edge of thick wall
