The pipes with wall thickness diameter from 20mm(0.787inch) up to 80mm(3.150inch) 
 
Welded steel pipe: 
Welded steel pipe is steel plate with the bending deformation of round, square and other shapes and then welded into the surface of the pipe joints. Welded steel pipe used is steel or steel billets. We supply of welded steel pipe manufactiong process is simple, high production efficiency, many varieties of different specificatios, equipment, less captial, but the general strength less than seamless. 
Since the 20th century, 30 years, with high-quality steel rolling prodiction, as well as the rapid development of welding and inspection technology advances, continually raising the quality weld, welding steel pipe increasing number of varieties and specifications, and in a growing number of areas instead of non-Steel Pipe, than the seamless steel pipe welded steel pipe and low cost, high production efficiency. 
Please consult us for any project or requirements.
