We supply a full range of carbon steel welded pipes, including straight seam pipes (ERW/LSAW) and spiral welded pipes. Manufactured from high-quality low-carbon or low-alloy steel strips/plates through high-frequency welding or submerged arc welding processes, our products offer excellent strength, weldability, and cost-effectiveness, making them widely suitable for building structures, fluid transportation, mechanical manufacturing, and low-pressure pipeline systems.
