Hydraulic Power Casing Tong
The TQ series of hydraulically powered casing tongs are widely used for making-up or breaking-out of casings and pipes. The casing tong is efficient, safe, reliable, and labor-saving. An open tong head design and swinging double jaw ensures a secure grip. The air tire clutch allows the wellhead tool to change gears while in operation. This series can be configured with a torque device for monitoring and managing pressure. This hydraulic casing tong has earned a National Invention Patent and are designed and manufactured according to SY/T5074 and API Spec 7K Specifications for Drilling Equipment.
Features
1. Widely used for making-up or breaking-out of casings and pipes
2. Complies with SY/T5074 and API Spec 7K
