The spirally welded steel pipe is manufactured using hot rolled steel strip which is spiraled at room temperature for welding. 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 the pipe.
With an annual production capacity of 600,000 tons, we can supply this tube with diameters between 159mm and 3500mm and thickness between 5mm and 28mm. We can make 3PE coating, epoxy resin coating, and black paint coating for spiral pipes. Our anti-corrsion coating is of good quality. All our products are manufactured in accordance with ASTMA53, ASTMA252, API5C, GB/T9711.1, or GB/T9711.2 or other primary standards. Our spirally welded steel pipe is ideal for the transportation of natural gas, water, coal gas, heating, steam, and so on. It can also be applied in piling or steel structure construction fields.
