The High frequency galvanized square pipe and round pipe welding machine is used to manufacture cold pipe and cold rolled coils into a tube-shaped blank and its subsequent parts to produce Φ20mm-Φ63.5mm circular tube welding with a thickness of 0.5mm-2.0mm Into the tube, edge heating is performed by a solid-state high-frequency welding machine, longitudinal seam welding is performed in the roller of the tube welding machine, cooling, further sizing or shaping, and on-line cutting of the annular pipe according to the measured length. The finished product will be round, square or rectangular pipes.

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

Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development.

The strength of the spiral welded pipe is generally higher than that of the straight welded pipe. It is possible to produce a welded pipe with a larger diameter by using a narrow blank, and it is also possible to produce a welded pipe having a different pipe diameter with a blank of the same width.

However, compared with the straight pipe of the same length, the weld length is increased by 30 to 100%, and the production speed is low.
