Thick-walled spiral steel pipe/anti-corrosion steel pipe/epoxy coal pitch anti-corrosion spiral steel pipe market, thick-wall spiral steel pipe refers to a spiral steel pipe whose wall thickness is slightly thicker than that of ordinary spiral steel pipes. Compared with ordinary wall thickness spiral steel pipes, the advantages are: high compressive strength, high impact strength, high safety performance and longer service life. The implementation standards are, and.
Thick-walled spiral steel pipe forming process
. Before spiral steel pipe forming
Spiral steel pipe adopts advanced double-sided submerged arc welding manufacturing process, which can achieve welding at the best position , it is not prone to defects such as wrong edges, welding deviations and incomplete penetration, and it is easy to control the welding quality and position. The spiral steel pipe adopts a special welding process, which can be welded at the best welding position without any errors and defects. This can ensure the qualification of the spiral steel pipe and the quality is well guaranteed.
Spiral steel pipe forming
During the forming process of spiral steel pipe, the steel plate must be evenly deformed, with small residual stress, and no scratches on the surface. Therefore, the steel plate for making spiral steel pipe must be carefully selected, and the surface must be uniform and free of scratches. 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, it has advantages that other processes cannot match and can meet the needs of Users have more requirements in terms of spiral steel pipe specifications. The diameter and size range of spiral steel pipes must be flexibly controlled and the good advantages of the spiral steel pipes should be utilized.
