Tube Mill as API stranded comprises of strip preparation, pipe forming, welding, cooling, sizing straightening, pipe cut-off unit and pipe take off unit. 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 complete pipe. After welding, the welding portion is scrapped by bead scrapping unit then the tube is cooled in 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 table.

The pipes are aligned at the fixed testing head: The feeding beams receive one pipe and move into in the axis of the tester. The lifting mechanism provides the pipe axial plane with the tester. At its upper part, the pipe is centered with supports adjusted at the level requested by the pipe diameter, without pressing it, in order to allow for its expanding during testing. The pipe is also centered on the testing heads; it is pressed on the front sealings, by getting closer the fixed head and the mobile head on the carriage. The sleeves are profiled according to the pipe ends profiles (deburred preceding). The panel assembly contains cabinets for PLC and for AC drives. The cabinets will also contain interfacing io modules. The cabinets will be made of metal structures of high quality, painted in electrostatic field.

We produce the entire range of products by making use of quality-approved raw materials sourced from the trusted vendors present in the market. Also, the inputs are cross checked by our quality experts. Buyers can place bulk as well as urgent orders with us and we make sure to deliver the same on time.

Steel slitting machine the coil end upto the slitter. Then its drive is disconnected. Slitter moves the slitted strips further. Slitted strips are threaded through loop table and drag tensioner into the recoiler drum. Recoiler winds one turn on loose coil.

Steel coil slitting line is expanded. Snubber roll rotates the coil. Peeler breaks the straps and brings the pre end upto pinch roll. The pinch roll drives the coil end upto the slitter. Then its drive is disconnected. Slitter moves the slitted strips further.

Slitting Line functions as a constant speed type. Firstly, the coil is loaded on the coil car by E.O.T. crane and brought to the uncoiler by operating the coil car. Coil car centralizes the coil with the uncoiler mandrel and the coil is mounted on the uncoiler which results in the expansion of Mandrel. The Snubber roll rotates the coil. Peeler breaks the straps and brings the pre end upto Pinch roll. The Pinch roll drives the coil end upto the slitter. Then its drive is disconnected. Slitter moves the Slitted Strips further. Slitted Lines are threaded through loop table and drag tensioner into the recoiler drum. Recoiler winds one turn on loose coil. Then drag tensioner and loop are put into operation. Slitter and recoiler run simultaneously in synchronization. As the coil build up, the recoiler RPM correspondingly goes down to keep desired constant line speed. This process goes on until the end of coil on uncoiler. The Slitted coil is pushed on the exit coil car trolley through a pusher plate operated by hydraulic cylinder. The side Slitted Scrap is wound on the scrap winder units provided on both sides of the slitter. Features High quality of metal usedCorrosion resistantAccurate working
