TB casing back-up tong
TB casing back-up tong is a patented product, used to perform casing operation by combined with casing power tong and can ensure connection quality and eliminate deformation of main tong under large torque. The back-up tong features safety, reliability, labor-saving, and high efficiency. There are two control style: pneumatic and hydraulic. The back-up tong is supplied with a torque sensor to measure precisely connection torque. The tong is designed and manufactured according to Industrial standard SY/T5074 and API Spec 7K “Specification for Drilling Equipment”.
