API 7K casing hydraulic power tong
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.
