1. Brief introduction

The mill is intended for manufacturing of round pipe of Φ10mm-Φ80 mm with thickness of 0.4mm–3.5mm 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.

FAQ:

1.Does one machine can only produce one style pipe?

Not exactly. Our machines can produce more kinds of pipes by change their rollers.

2. Do you have after sales support?
Yes, we are happy to give advice and we also send skilled technicians to your place to support the technical guidance. We will let your machines running that in order to keep your business running.

3. What can you do if the machine broken?
