Hydraulic Power Tong is also called the Drill Pipe Power Tong, Our ZQ series drill pipe power tong is an ideal well head tool for oil drilling, widely applied for making-up and breaking-out in offshore and onshore drilling operations and workover operations. Open-throat design of the ZQ series allows the tongs to escape from drilling pipe freely with high mobility. The tong is a combination of spinning tong and torque tong. It substitutes cathead, manual tong and rotary rope in making-up and breaking-out. The tongs are designed and manufactured according to API Spec 7K Specification for Drilling Equipment

Application

It is used in oil field for upper unloading the casing or casing screw thread during the operation of lower casing.
The casing power tongs are extensively used in oil field for upper unloading the casing or casing screw thread during the operation of lower casing. The products are powered by hydraulic pressure, adopting the tilt cylinder type high pulling torque motor and mechanical type shift gear to make the tongs structurally simple and reliable, operationally safe and convenient. The tongs' pressure, touque and number of turns can be monitored and controlled by computer by equipped torquemeter. Relevant national patents of invention have already achieved. The casing power tongs meet the requirements of SY/T5074 standard and API Spec 7K specifications.
