ZQ Drill Pipe Power Tong
ZQ series of drill pipe power tongs are ideal wellhead tools for well drilling, which are widely used for make-up and break-out operation in onshore and offshore drilling and workover processes. The tongs are safe and labor saving for operation, which improves the work efficiency. ZQ series of tongs are open-mouth type, which can freely break out the string, and has very good flexibility. The torque tongs and spinning wrench are integrated as a whole, which can replace the roles of cathead, hanging tongs and spinning rope in the make-up and break-out operation. The design and manufacture process of the power tongs conform to SY/T5074 standard and API Spec 7K specification.
