Product Details

Product Description

The spiral welded steel pipe is manufactured using hot rolled steel strip which is spiraled at room temperature to be welded. Automatic submerged arc welding is the most commonly used method in the spiral tube production, and the end products come with welding seam both inside and outside. We can make 3PE coating, epoxy resin coating, and black paint coating for spiral pipes. Our anti rust coating is of good quality. Our spiral welded steel pipe is ideal for transportation of natural gas, water, coal gas, heating steam, and so on. It can also be applied in piling or steel structure construction fields.
