Hot and Cold Roller Coil Tube Making and Welding Machine

hot roller coil tube machine cold roller coil tube making machine tube welding machine

2.machine Summary

Finished product will be of round, square or rectangular pipe.The mill is intended for manufacturing of round pipe of Φ38mm-Φ127mm with thickness of 1.5mm–5.0mm from cold-rolled and hot-rolled coil strip by means of un closed 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. This machine can be made into different sizes of tube by changing the molds.

1.1. Parameters:

1.3. Mandrel expansion by hydraulic

• Five-roll Flattener

2.1 Brief:

There are pairs of nipping and sending roller. Flatten rolls are arranged for two top and three below. Nipping and sending is pressured by hydraulic cylinder, flatter roll motor is cogged by worm wheel and worm screw reduced speed, the worm screws in front and one in back can come true be in-phase by sleeve connecting, which can ensure top leveling roll and under leveling roll be parallel, thereby which reach in the intention of flatten.
