Tube Pipe Mill

Rishbin is an established manufacturer of many types of high frequency welded tube mill with tube diameter from 8 mm to 610mm, square & rectangular tube mill for making ERW/API and related applications rating maximum up to 120m/min which is based on German and Taiwan Design and technology. Our tube mill advantages are the custom design, horizontal accumulators, digital length control, competitive tooling, very competitive pricing, good delivery time, installation and start-up assistance, very good service & training and very good warranty.

Tube mill includes Fully mechanized system with Automatic feeding spiral system with NC cold saw cut of the unit and High-frequency solid state power saving Welders.

Tube mill mainly consists of strip preparation, pipe forming, welding, cooling, sizing straightening, pipe cut-off unit, and pipe take-off unit. A forming motor and a sizing motor and power transmission are done by worm gearboxes driving the whole machine.

The strip first requires leveling and straightening which is done by passing the strip through strip leveler, pinch rolls, and guide rolls. After this, the strip is passed through various forming rolls where the strips are converted into open seam pipe. Then it reaches the welding unit where the edges of the open seam tube are heated by HF induction generator (or any other welding equipment). Immediately after heating, the edges of the pipe are forged (fused) in the squeezing unit and it takes the shape of the complete pipe.

After welding, the welding portion is scrapped by bead scrapping unit then the tube is cooled in the cooling jacket. For making it exact round the pipe is passed through sizing unit and then through Turks head for straightening. After this, the tube is cut into required length by a moving cutting machine and pushed to take off the table.
