P9 Seamless Steel Pipe Processing Method

1. The price of P9 Seamless Steel Pipe is divided into forging, stamping, roller, rolling, bending forming, expansion, etc. Several processing methods are introduced as follows:

2. Forging method: The end or part of the pipe is punched out by a swaging machine to reduce the outer diameter. The common type forging machine has a rotary type, a link type and a roller type.

3. Stamping method: The Thermal Insulation Pipes For PUR end is expanded to the required size and shape with a tapered core on the press.

4. Inflating method: one is to place rubber in the tube, and the upper part is compressed by a punch to make the tube protrude and formed; the other method is hydraulic expansion forming, filling the liquid in the middle of the tube, liquid

The body pressure drums the tube into the desired shape, and most of the production of the bellows is this method.

5. Bending forming method: There are three methods are more commonly used, one method is called stretching method, the other method is called pressing method, the third roller method, there are 3-4 rollers, two fixed rollers, one

Adjust the roller, adjust the fixed roller pitch, and the finished pipe fitting is bent.

6. Roller method: The core is placed in the tube, and the outer circumference is pressed by the roller for the edge processing.

7. Rolling method: Generally, the mandrel is not used, and it is suitable for the inner edge of the thick-walled tube.
