With more than 30 years of manufacturing experience, we deliver spiral welded steel pipes that meet the highest quality and safety requirements of international projects.

What is a Spiral Welded Steel Pipe?

A spiral welded steel pipe, also called a spiral submerged arc welded (SSAW) pipe, is produced by forming a steel strip into a cylindrical shape and welding the seam in a continuous spiral direction. Compared with longitudinal welded pipes, spiral welded pipes allow the production of large diameters from a single strip width, which makes them an economical and efficient choice for large-scale pipeline systems.

Product Features

Our spiral welded steel pipes are manufactured with double-sided submerged arc welding, ensuring strong and reliable weld seams. The pipes offer excellent resistance to internal pressure and external loads, and the spiral seam distributes stress evenly along the pipe body. Each pipe is produced under strict quality control, with hydrostatic testing, X-ray inspection and ultrasonic testing available upon request to guarantee performance.

We supply spiral welded steel pipes with outer diameters from 219 mm to 3620 mm and wall thicknesses from 5 mm to 32 mm. Standard materials include Q235B and Q345B carbon steel, and the pipes can be produced according to GB/T 9711, API 5L and ASTM A252 standards. Custom lengths, bevelled ends, and anti-corrosion coatings such as 3PE and FBE can also be provided according to project requirements.
