ZQ drill pipe powertongs is an ideal well head tool for oil well,and 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 design and manufactured according API SPEC 7k "Driling and Well serving Equinment.
