ZQ127/25 Drill Pipe Power Tong is an open type power tong used for loading and unloading 2 3/8 "-3 1/2" drill pipes, 2 3/8 "-4 1/2" oil pipes, and 4 1/2 "-5 1/2" casing in oilfield well repair operations.

Characteristics:
The tong head used inner curved roller climbing and clipping mechanism and needn’t to change any part during making up or breaking out the tubing thread.
Four-gear rotation is adopted for large speed regulation range. And the rated torque is large.
The braking mechanism set above the tong head cover.It’s convenient for adjustment and maintenance.
The new hydraulic backup tong and the master tong form a combined tong, operate the control valve on the master tong, the backup tong will automatically clip or simultaneously loosen the tube pillar.
Adjust the oil supply pressure, users can obtain the best make-up torque of various kinds oil tube.
Users can equip hydraulic suspension according to needs, the suspension valve compactly contact with hand control valve, so it is easy to control.
Users can equip torque control system according to needs, which can accuracy control make-up torque.

Specific requirements for power pliers
The speed operation of the power tong shall not be less than 2 gears.
All supporting purchased and outsourced parts should have quality certificates, and the power pliers should be tested simultaneously after assembly.
After the assembly of all components of the power tong is qualified, a no-load test should be conducted. During the no-load test, the power clamp should run smoothly without any obstruction or abnormal noise. The operating system should be flexible, accurate, stable, and free from local overheating.
In addition, when clamping the pipe column with the jaw plate, the jaw plate roller should be in the position specified in the jaw plate design, clamped stably, and not slip; Retract flexibly without obstruction.
