HGF125 high-frequency welded pipe production line is the special equipment providing longitudinally welded pipe and cold formed steel for industries such as metallurgy, construction, transportation, machinery, vehicles and so on.
Used new technology to produce square and rectangle pipe directly.
Taking cold or hot-rolled steel as raw materials, through cold-formed and high-frequency welding method to produce the suitable pipe.
Material of the coil: HR coils

The operator operates the crane to directly lift the steel coil to the feeding center of the uncoiler. The uncoiler starts the mandrel expansion function to tightly stretch the steel coil onto mandrel. The uncoiler rotates actively to the uncoiling position. Manually, the welding strip (the welding strip fixed to the plate head after slitting) or the packing strap is cut off and removed (this process can be completed by the crane operator). The pressure rollers are used to guide the strip to the clamping and leveling workstation. The clamp rollers hold the steel strip forward and enter the leveler to level the strip head.

HG114 ERW Tube Mill Machine is a continuous pipe production equipment integrating cold roll forming and high-frequency resistance welding (ERW). It mainly produces round tubes with a diameter of φ32–114mm as well as matched square and rectangular tubes, suitable for construction, fluid transportation, structural pipes and other applications, featuring high automation and stability.

Summary:
The mill is intended for manufacturing of round pipe of Φ19.05mm-Φ63.5mm with thickness of 1mm–4mm from cold-rolled and hot-rolled coil strip by means of unclosed 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.
The manufacturing process provides for the uses of coiled strip precut in required width sizes in slitting machine.

The HG20 is a dedicated in-line system designed for manufacturing small-diameter, thin-walled high-frequency straight-seam welded pipes (ERW). It specializes in the continuous cold roll forming and high-frequency welding of round pipes, as well as square and rectangular pipes, and is suitable for the mass production of small-specification pipes applied in light industry, construction, hardware and other sectors.

ERW426 tube mill is a combination of equipment installed in a line for the production of High Frequency Induction Welded (HFIW) carbon steel tubes. The process involved is cold forming of carbon steel strip in circular shapes, longitudinal welding, sizing, converting into specified shape and cutting to pre determined length.

HG76 high frequency straight weld pipe production line is used to manufacture weld stainless steel pipe of Φ32mm-Φ76mm with 1.5mm-4.0mm of wall thickness.
