TQ series of hydraulic casing tongs are widely used for making-up or breaking-out of casings or pipes. The series of casing tongs are wholly hydraulic driven. The tongs are configured with a large-torque motor and perform mechanical gearchange. Structure is simple and operation is safe. The casing tongs can be supplied with torque device to perform computer monitoring and managing on pressure, torque and rounds. The casing tongs are designed and manufactured according to API Spec 7K standard
