ASTM A53 A36 ASME B36. Welded Spiral Steel Tube, SSAW Welded Pipe, Screw Steel Tube

Name: ASTM A53 A36 ASME B36. Welded Spiral Steel Tube, SSAW Welded Pipe, Screw Steel Tube
Brand: Hongkun
Rating: 5.0 (25 reviews)

Spiral steel pipes are created by forming a steel coil through extrusion at normal temperatures, employing the technology of double wire and double-faced submerged-arc welding. Also referred to as helix spiral steel pipes, these are crafted from low-carbon or low-alloy structural steel strips rolled into a tube at a specific helix angle, known as the molding angle. The resulting tube is constructed with welded joints and can be produced using a narrow strip to achieve a large diameter.

In the molding process of spiral welded steel pipes, the steel plate undergoes uniform deformation and light residual stress, ensuring a surface free from scratches. This method allows for greater flexibility in thicknesses and diameters, particularly advantageous in producing high-grade, thick pipes with small or medium apertures. These techniques offer unparalleled advantages in meeting diverse requirements.
