KHT5500-66 KHT9625.1.15.1 Braking staple Drill pipe power tongs

ZQ127/25 drill pipe power clamp is an open type power clamp used to unload 2 3/8 “-3 1/2” drill pipe, 2 3/8 “-4 1/2” tubing and 4 1/2 “-5 1/2” casing in oilfield workover operations.

features/Characteristics:

1. The pliers head adopts an advanced clamping mechanism, and the jaw plate and the tooth seat can be connected separately. When clamping different pipe columns, it is very convenient to change the tooth block and the tooth seat.

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.

2. Two-speed transmission, high-speed speed and large low-speed torque, meeting the requirements of different pipe strings.

Four-gear rotation is adopted for large speed regulation range. And the rated torque is large.

3. The clamp head brake mechanism is arranged on the clamp head cover plate, which is extremely convenient for adjustment and maintenance.

The braking mechanism set above the tong head cover.It’s convenient for adjustment and maintenance.

4. The new hydraulic back pliers are matched with the main pliers to form a combined pliers. The manual reversing valve on the main pliers is operated. The back pliers are synchronized with the main pliers to clamp or release the pipe string synchronously, and the action is flexible and reliable.

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.

5. Adjust the oil supply pressure to obtain the best torque required for the buckling of various steel grade oil pipes.

Adjust the oil supply pressure, users can obtain the best make-up torque of various kinds oil tube.

6. Hydraulic hanger can be selected. The hanger valve is compactly connected with the manual reversing valve for easy operation.

Users can equip hydraulic suspension according to needs, the suspension valve compactly contact with hand control valve, so it is easy to control.

7. An optional torque control system is available to accurately control the buckling torque.

Users can equip torque control system according to needs, which can accuracy control make-up torque.

8. This product has many national patents.

This product has owned several patent of China
