The spiral steel pipe is a spiral seam steel pipe which is made of steel coiled coil as raw material, which is often heated and extruded, and welded by automatic double wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling through multiple rolls, the strip is gradually rolled up to form a circular tube blank with an open gap. The reduction of the pressing roll spiral steel pipe supplier is adjusted to control the weld gap in 1~ 3mm and make the ends of the solder joint flush.

Advantages of spiral steel pipe:

1.Exquisite workmanship and strict testing

During the forming process, the steel sheet is uniformly deformed, the residual stress is small, and the surface is not scratched. The processed spiral steel pipe has greater flexibility in the size range of diameter and wall thickness, especially in the production of high-grade thick-walled pipes, especially small and medium-diameter thick-walled pipes, which have advantages over other processes and can satisfy users. More requirements on the specifications of spiral steel pipes.

2.Wide range of uses and complete specifications

Spiral steel pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction and so on. For liquid transportation: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: for piling pipes, for bridges; for piers, roads, building structures,

3.Factory inspection, timely delivery

According to the quality inspection results of spiral steel pipes, spiral steel pipes are generally divided into three categories: qualified products, repaired products and waste products. Qualified products refer to spiral steel pipes whose appearance quality and intrinsic quality meet the relevant standard or delivery acceptance technical conditions; the repaired products refer to the appearance quality and the intrinsic quality are not completely in accordance with the standard and acceptance strips.
