Due to
ssaw steel pipe welding technology, in addition to such high production efficiency; produce less auxiliary time, saving time change electrode; welding conditions clean and free of spatter, saves clean-up time; high weld quality. Spiral Pipe factory for delivery to provide the necessary conditions so that large spiral pipe production time is guaranteed, so it is widely used with.
Spiral submerged arc welded steel pipe is a spiral bending, were sewn inside and outside seam welded steel pipe with spiral submerged arc welding. For the following reasons it is widely used in large-diameter pipe production:
1) Just change the angle formed, you can use the same width of the strip steel production of various calibres;
2) Because it is a continuous bending, the pipe length unlimited length;
3) spiral weld uniformly distributed over the entire circumference of the pipe, the pipe high dimensional accuracy, intensity is higher;
4) cost of equipment cheap, easy to change the size, suitable for small quantity and variety of steel production.
