Stainless Steel Weld Elbow Common processing methods:

1. Rolling method: Generally, a mandrel is not required when bending stainless steel pipes, which is suitable for the inner round edge of thick-walled stainless steel pipes.

⒉ Roller method: Place a mandrel in the stainless steel pipe and use a roller to push the outside at the same time.

3. Stamping method: Use a tapered mandrel on a punch press to expand the end of the stainless steel pipe to the required size and shape.

4. Bulging method: First place rubber in the stainless steel pipe, and compress it with a punch on the top to make the stainless steel pipe bulge out; another method is to use hydraulic pressure to bulge, pour liquid into the stainless steel pipe, and the liquid pressure can bulge the stainless steel pipe into the required shape. Generally, most of the production of corrugated pipes adopts this method.

5. Direct bending forming method: There are 3 specific methods that are commonly used in stainless steel pipe bending processing. One is called stretching method, another is called stamping method, and the third is called roller method. There are 3-4 wheels, two fixed wheels, and one adjustable wheel. Adjust the fixed rod distance, and the finished stainless steel pipe fittings are bent.
