Product Types & Applications
Longitudinally Welded Pipes
Straight seam welded pipes feature simple production processes with high efficiency and cost-effectiveness. Available in longitudinal submerged arc welding (LSAW) and electric resistance welding (ERW) variants.
Square Tubes
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%.
SSAW Spiral Welded Pipes
Spiral welded steel pipes offer superior strength and are ideal for oil and gas transportation, pipe piles, and bridge construction applications.
Thick Walled Coiled Tubes
Available in diameters from 400mm to 3000mm with wall thicknesses ranging from 4mm to 300mm. Custom lengths available to meet specific project requirements.
