Straight seam welded pipes offer simple production processes with high efficiency and cost-effectiveness. Available in longitudinal submerged arc welding (LSAW) and electric resistance welding (ERW) types, these pipes are ideal for smaller diameter applications.
Square and rectangular tubes are manufactured from rolled steel strips through flattening, curling, and welding processes. Standard delivery lengths range from 4000mm to 12000mm, with wall thickness tolerances maintained within 8-10% of nominal specifications.
Spiral welded pipes provide superior strength and are manufactured using steel strips bent into circular shapes. These pipes are extensively used in oil and gas transportation, pipe piles, and bridge construction projects.
Thick walled coiled pipes are available in diameters from 400mm to 3000mm with wall thicknesses ranging from 4mm to 300mm. These pipes are produced through hot-rolling processes to meet specific industrial requirements.
