The High frequency galvanized steel welded square and round pipe making machine is intended for manufacturing of round pipe of Φ12mm-Φ50mm with thickness of 1.0mm–3.25mm from cold-rolled and hot-rolled coil strip by means of enclose tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.Finished product will be of round, square or rectangular pipe.

Working Flow： Raw material (strip steel roll) – Material feeding – End cutting and butt welding (hand welding) – Strip storage cage – Material feeding and forming – High frequency welding – Removing outer burr – Cooling water jacket – Fix the diameter and straightening – Cut off with flying saw – Material unloading (Manually stow and bind up) – Inspection – Storehouse
