The ERW pipe mill is designed for producing API, EN, ASTM, and GB/T standard pipes for transporting water, gas, and oil, as well as construction pipes. This high-frequency straight seam welded pipe mill processes fixed strips after slitting, forming them into pipes through roller bending, with edges melted via high-frequency current and welded by squeeze rolls.
Engineered for precise fabrication of cold/hot-rolled and galvanized coils, this ERW pipe making machine delivers tight production tolerances. The resulting round, square, and rectangular pipes serve diverse industries including metallurgy, construction, transportation, machinery, and automotive.
Raw material (strip steel roll) → Material feeding → End cutting and butt welding → Strip storage cage → Material feeding and forming → High frequency welding → Removing outer burr → Cooling water jacket → Diameter fixing and straightening → Cut off with flying saw → Material unloading → Inspection → Storage
