LSAW SSAW ERW Sch40 Carbon Steel Pipe 0.6-30mm Wall Thickness for Oil Gas Drilling Applications
Zhengde welded steel pipes are manufactured through advanced rolling and welding processes, available in various types including LSAW, SSAW, and ERW configurations. These pipes feature wall thicknesses ranging from 0.6mm to 30mm and are designed for demanding oil and gas drilling operations.
LSAW pipes offer straightforward production processes with high efficiency and cost-effectiveness. Available in Schedule 40 specifications with diameters from DN15 to DN600.
SSAW pipes provide enhanced structural strength and can be manufactured from narrow billets to create larger diameter pipes. Weld length increases by 30-100% compared to straight seam alternatives.
ERW pipes utilize resistance welding technology for consistent, high-quality joints suitable for various industrial applications.
Available in diameters from 400mm to 3000mm with wall thicknesses from 4mm to 300mm. Custom lengths available upon request.
