Carbon Steel Welded Pipe Production Line, Brand Name : Redstar

We are offering carbon steel welded pipe production line.
electric resistance welded (erw) tubes are made by forming the steel strip into a tubular round section by progressive movement through a set of specially designed rolls. The butted ends of the strip are welded by high frequency induction welding process without any filler material. The hot weld-flash formed due to welding is removed internally (fin-cut) and externally by the deburring units. Turks head and sizing rolls provided at the end of the tube mill ensure straightening and sizing of the tubes into required sections like rectangular, square, elliptical and oval. The tubes are cut into required length and undergo annealing, pressure testing, eddy current testing, straightening or cutting depending upon the applications.
