TQ series of Casing Tongs are widely used for making up or breaking out pipes or casings in diameters of 4 1/2~13 3/8 inch. The tong heads are designed"open"type and can freely clamp and escape from the casing. TQ Casing Tongs are safe, reliable and easy to handle with high mobility. This series of tongs can be connected to computer controlling units and can serve as ideal well mechanical tool for surface operations in oil fields. National Invent Patent of the tong has been got.
