Product Types & Applications
Longitudinally Welded Pipes
Straight seam welded pipes feature simple production processes, high efficiency, and lower costs. Available in longitudinal submerged arc welding (LSAW) and electric resistance welding (ERW) variants, these pipes are ideal for smaller diameter applications where production speed is prioritized.
Square Tubes
Square and rectangular tubes are manufactured from rolled steel strips through unpacking, flattening, curling, and welding processes. Standard delivery lengths range from 4000mm to 12000mm, with wall thickness tolerances maintained within 8-10% of nominal specifications.
SSAW Spiral Welded Pipes
Spiral welded pipes offer superior strength compared to straight seam alternatives and can be produced from narrow billets to create larger diameters. These pipes are extensively used in oil and gas transportation, pipe piles, and bridge construction projects.
Thick Walled Coiled Tubes
Thick walled coiled pipes are manufactured through hot-rolling processes with diameter ranges from 400mm to 3000mm and wall thickness from 4mm to 300mm. Available in various materials including hot-rolled and cold-rolled variants to meet diverse industrial requirements.
