Suitable for tubing, small drill pipe and small casing in the range of 73-140mm (2 7/8 "-5 1/2"),Compared with other workover power pliers of the same type, it has simple structure, easy operation, reliable performance, long service life,High output torque and other advantages. It can be used in both onshore and offshore oil fields. The use of this product can reduce the labor of workover worker
It can be used in both onshore and offshore oil fields. The use of this product can reduce the labor intensity of workover workers, improve work efficiency and workover quality.
1. The master tongs and back up tongs adopt the clamping mechanism of the internal curved surface roller climbing. The dies are used in common. The die seats can be changed to need the different calibers of pipe clamping.
2. The rotation of master tongs and backup tongs is controlled by the same manual reversing valve. The operational steps are simple and reliable.
3. The main tongs is equipped with four-gear shifting mechanism, when adjusting the system pressure and flow appropriately, it can get the torque and speed value which is applicable to the wider range
4.The manual reversing valve is equipped with safe controlling valve, which can control the system pressure effectively and play the protective role when overloading. (It shall be matched when customer requires)
5. The power tongs has a spring hanger or hydraulic spring hanger. The hydraulic controlling system which is equipped with the slowing up and down power tong and hydraulic spring hanger can adjust the height of power tong in the single lift sub working for the option of user.
6. The power tongs is installed a torque controlling system. When the torque reaches the setting value, the power tongs will stop rotating automatically. This control system is convenient for the power tongs to apply the best make-up torque to the different sizes of pip string. This system's torque sensing equipment can be connected with the torquemeter. The torquemeter can indicate, record and print the torque value, and give alarm signal when overloaded (It shall be matched when customer requires).
