Project Name: ERW660 high frequency welded pipe production line
Project location: Daqing Warwick
Project time: 2003
Project Overview: in March 2003, Dalian SAGE heavy industry equipment Co., Ltd. provided a 1200KW high frequency welded pipe for the 219~ (1200KW) 610 oscillating power for Hua REK. Under the normal operation of the unit, it was 219 x 11, the induction welding speed of steel tube was 15 meters per minute, and the welding speed of the steel pipe of 14 x 508 was 9 m / min. The clock. The frequency of 1200KW high frequency welding machine, in order to take into account the thickness of 6mm thin-walled steel pipe, the heating frequency is 225 + 25KHz.
