Seamless steel pipes, renowned for their strength and integrity, are cylindrical steel conduits devoid of any welding or seams. Commonly available in a variety of sizes, from small diameters of 10mm to larger ones of 300mm, with wall thicknesses ranging from 1mm to 50mm, they cater to diverse industrial requirements.
ERW is the general term of welded steel pipe, which refers to the seamless steel pipe produced by rolling the thick steel plate into a round steel pipe or a square steel pipe and being welded by electric welding. Widely used in hydropower stations, municipal engineering drainage pipes, drinking water transportation and other engineering projects.
