TB365-35 Casing Backup Tongs TQB casing backup tong is a patented product, used to perform casing operation by combining with casing power tong and can ensure connection quality and eliminate deformation of main tongs under large torque operation. The backup tongs can increase the safety and reliability of casing operation, reduce labor intensity, and raise working efficiency. The backup tong is supplied with a torque sensor to measure precisely the connecting torque of casing. The backup tong are designed and manufactured according to API Spec 7K “Specification for drilling and well serving equipment”.
