Welding treatment of spiral steel pipe
The production of spiral steel pipes begins by feeding strip steel into a welded pipe unit. As the strip passes through a series of rollers, it gradually forms a tube with an open seam. The squeeze roller’s adjustment controls the size of the weld gap, typically kept between 1–3 mm, ensuring that both ends of the welding joint align properly. The precise control of this gap is critical for the quality of the weld.
