Common processing method of steel pipe
Common processing methods for steel pipe:
1. Forging method: use forging machine extend to the end or part of the tube, to reduce the outer diameter, commonly used forging machine are rotary, connecting rod, roller type.
2. Stamping method: use a tapered core on the punch to extend the pipe end to the desired size and shape.
3. Roller method: place the core in the tube,rolling the outer with a roller, used for the round edge processing.
4. Rolling method: generally it do not have mandrel, suitable for thick-walled tube with the round edge inside.
5. Bending method: There are three common methods: extension method, stamping method, roller method. There are three-four rollers, two fixed roller, a adjustment roller, adjust fixed roller distance, then finished pipe is bent.
6. Blowing method: one is placed in the tube rubber, the top with a punch compression, protruding shape the tube; another method is the hydraulic bulging shape, fill liquid in the middle of the tube, the liquid pressure to the drum drum into the required shape, the bellows mostly use this method.
