Drill Pipe Power Tong

Description

ZQ Series Drill Pipe Power Tong is an ideal well head tool for oil drilling, widely applied in making-up and breaking-out drill pipe and repairing well offshore and on land. 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 spinning rope in making-up and breaking-out. The tongs are designed and manufactured according to API Spec 7K “Specification for Drilling Equipment”.
