Advantages:

1. As long as the forming Angle is changed, the steel pipe of various diameters can be produced with the strip steel of the same width, which is easy to be adjusted.

2. Because it is continuous bending forming, the length of the spiral welded pipe is not limited, the length can be arbitrarily determined.

3. The spiral shape of the weld is evenly distributed on the circumference of the whole spiral steel pipe, so the size precision of the spiral pipe is high and the strength is strong.

4. Easy to change the size, suitable for small batch, multi - variety spiral pipe production.
