Product Types & Applications
Longitudinally Welded Pipes
Straight seam welded pipes feature simple production processes with high efficiency and low cost. Available in longitudinal submerged arc welding (LSAW) and electric resistance welding (ERW) variants, these pipes are ideal for smaller diameter applications where production speed and economy are priorities.
Square Tubes
Square and rectangular pipes manufactured from rolled steel strip through unpacking, flattening, curling, and welding processes. Standard delivery lengths range from 4000mm to 12000mm, with 6000mm and 12000mm being most common. Wall thickness tolerance is maintained within 10% for thicknesses ≤10mm and 8% for thicknesses >10mm.
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
Hot-rolled thick walled steel pipes available in diameters from 400mm to 3000mm and wall thicknesses from 4mm to 300mm. Custom lengths produced according to specific customer requirements.
