The production of ERW pipes begins with the selection of high-quality steel coils. These coils are subsequently unrolled, leveled, and cut to appropriate lengths. The edges of the sheets are then heated through electrical resistance, allowing for a strong bond to form when pressure is applied. The welding occurs in a controlled environment to ensure even heating and consistent quality. After the pipes are welded, they are subjected to a series of quality control tests, which include hydrostatic tests, ultrasonic inspections, and diametrical tolerances. This rigorous quality assurance process ensures that each pipe meets industry standards and can withstand necessary pressure levels during operation.
