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 cost-effectiveness are priorities.
Square Tubes
Our square and rectangular tubes are manufactured from rolled steel strip through precision processing. 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 and are manufactured using narrow billets to produce larger diameter pipes. These pipes are extensively used in oil and gas transportation, pipe piles, and bridge construction applications.
Thick Walled Coiled Tubes
Our thick wall coiled tubes are available in diameters from 400mm to 3000mm with wall thicknesses ranging from 4mm to 300mm. Custom lengths are produced according to specific customer requirements.
