ASTM A252 Grade 3 Welded Carbon Steel Spiral Pipes, Large Diameter Steel Tubes, SSAW Spiral Steel Pipes

The production of spiral steel pipe involves shaping a steel coil through extrusion at ambient temperature. This process utilizes the technology of double wire and double-faced submerged-arc welding. Commonly known as helix spiral steel pipe, it is crafted from a low-carbon or low-alloy structural steel strip rolled into a tube at a specific helix angle, referred to as the molding angle. The resulting tube is formed by welded joints and can be manufactured using a narrow strip to achieve a large diameter pipe.

Throughout the formation of spiral welded steel pipe, the steel plate undergoes uniform deformation, minimizing residual stress and preventing surface scratches. This characteristic makes the surface of the spiral steel pipe smooth. Notably, spiral steel pipes offer greater flexibility in terms of thicknesses and diameters. This flexibility is particularly advantageous when producing high-grade thick pipes with small or medium apertures, providing unmatched benefits in meeting diverse requirements.
