Description
Hydraulic Backup GK16.200.000 is used as part of hydraulic tongs GKSH-1200MT (MK), GKSH-1500MT (MK) and GKSH-1600MT (MK) to compensate reactive torque on the tong and prevent possible rotation of the pipe string in the well during make-up and break-out operations, for tubing with outer diameters from Ø 60 mm (23/8 ") to Ø 159 mm (61/4"). It has two sets of jaws (each consists of 2 jaws) with ranges:
• Ø 60 mm (2 3/8 ") - Ø 108 mm (4 1/4")
• Ø 108 mm (4 1/4 ") - Ø 159 mm (6 1/4").
The design of the Backup device is reversible; there is no need to turn the body over, and to rearrange the jaws.
Mounting of the Backup device below a hydraulic tong is possible in the field conditions, without any rework.The biting force by hydraulic backup is synchronized with the torque generated by the tong, the pressure is adjusted by a standard valve installed on the hydraulic module of the tong.
