Our factory specializes in the production of high-frequency electric resistance welded (ERW) carbon steel pipes, with an extensive size range covering outer diameters from 21.3mm to 660mm and wall thicknesses from 1mm to 20mm. The manufacturing process begins with high-quality steel coils, which are uncoiled, leveled, and progressively formed into a cylindrical shape through precision roll forming. The edges are then welded using high-frequency induction technology, ensuring a strong, seamless bond without filler metals. After welding, the pipes undergo heat treatment to refine the weld zone microstructure, followed by sizing, straightening, and cutting to specified lengths.

To guarantee superior quality, our production line incorporates automated ultrasonic testing (UT), hydrostatic pressure testing, and dimensional inspection systems, ensuring compliance with API 5L, ASTM A53, EN 10219, and other international standards. Our advanced facilities enable us to deliver consistent, high-performance ERW pipes for applications in oil & gas, construction, water transmission, and structural engineering.

With strict process control and a commitment to excellence, we provide reliable ERW pipe solutions tailored to global market demands.
