Casing tongs are widely used for making-up or breaking-out of casing or pipes. The casing tong features high-efficiency, safety, reliability, labor saving, and ensures connection quality. Tong head is designed as open and equipped with advanced swing-type double jaw assembly, which can secure reliable clamping. This series of casing tongs can be configured with torque device to perform computer monitoring and managing on pressure, torque and rounds. The casing tong has been granted the National Invention Patent. The tongs are designed and manufactured according to industrial standard SY/T5074 and API Spec 7K "Specification for Drilling Equipment"
