Since the 1930s, with the development of strip steel rolling production and the improvement of welding and inspection technology, the quality of welds has been continuously improved, and the variety and specifications of welded steel pipes have been increasing, and they have replaced seamless steel pipe. Welded steel pipe is divided into SSAW steel pipe and LSAW steel pipe according to the form of welding. Here we will introduce you SSAW steel pipe. What is a  SSAW steel pipe  (spiral submerged arc welded steel pipe)? SSAW steel pipe is formed by spirally bending hot-rolled strip steel, and submerged arc welding is used to weld inner and outer seams to make spiral seam steel pipes (also known as spiral welded pipes, spiral pipe spiral steel pipes). It can be widely used in the production of large diameter steel pipes for the following reasons: 1) Only if change the forming angle, steel pipes of various calibers can be produced from strips in the same width; 2) The fixed l

1.Outer Diameter Tolerance ERW steel pipe : Cold-formed and sizing by reducing the diameter by 0.6%. The outer diameter is controlled accurately and the fluctuation range is small, which is helpful to eliminate black leather buckles. Seamless steel pipe : Hot-rolling forming process and sizing completed at about 8000C. The raw material composition, cooling conditions, and cooling conditions of the rolls of the steel pipe have a large impact on outer diameter, so it is difficult to control the outer diameter accurately and fluctuate.  2.Wall Thickness Tolerance ERW steel pipe: using hot-rolled strip as the raw material, the thickness tolerance of modern hot-rolled strips can be controlled within 0.05mm, and seamless steel pipes are produced by round steel perforation, with large wall thickness deviations. The subsequent hot rolling can partially eliminate the wall thickness. Thickness non-uniformity, but currently the most advanced units can only be controlled within ± 5 to
