Line composition: Basic line-up(Entry to Run out) and optional lines(End facing,Straightening, Auto or manual Stacker,Hydrostatic unit, Painting and others),Process & automation control system.
The first process of producing 10 Inch Erw Tube is hoop slitting hot coil in a fixed width. After welding & removing bead through forming roll,the form of 10 Inch Erw Tube is sized at the sizing roll within the common difference,cut with lighteousness foot,going through roughing tube inspection and having degree of straight collected at straightner.The end section of tube goes through water pressure testing for correcting the pressure according to the size after being faced plain or bevel to its use.
