The casing back-up tongs are essential in casing operations and are designed to work with various casing power tongs used in the oilfield. These backup tongs improve the quality of thread connections, reduce deformation caused by high torque operations, and enhance safety and reliability. They also reduce labor intensity and increase operational efficiency. In both pneumatic and hydraulic control versions, these tongs feature a torque sensor for precisely measuring connection torque. Designed and manufactured according to SY/T5074 standards, they ensure high performance and reliability.
