TQ340/35N Casing Power Tongs
TQ340/35 Casing Power Tongs,including Type TZS-K Torque Monitor,is a type of casing tongs which adopts the hydraulic and pneumatic united drive, and widely used for making-up and breaking-out of 4~13 3/8pipe or casing in drilling operation of oil field. Open-throat design of the TQ casing tongs series allows the tongs to trip out of casing freely with high mobility. Planetary gearbox adopts air tube clutch, and it can shift gear under running and work high efficiently. Inputed number of casing can realize torque/length conversion in computer of Type TZS-K Torque Monitor. The Type TZS-K Torque Monitor can monitor and manage the status of the torque of casing and it is an ideal monitor of torque ,and has been granted the national patent.The tongs are designed and manufactured according to API Spec 7K “Drilling and well serving Equipment”.
