Features And Advantages
Hydraulic Tubing Tongs and Casing Tongs are essential API-standard power handling tools designed for oil and gas drilling, well completion and workover operations. They are specialized hydraulic power tongs used to perform automatic make-up and break-out of threaded connections for tubular strings. Tubing Tongs are compact, low-torque precision tools dedicated for small-diameter production tubing. In contrast, Casing Tongs are heavy-duty, high-torque hydraulic tools developed for large-diameter, thick-wall casing pipes. Both tools replace traditional manual tong operations, delivering mechanized, safe and high-efficiency pipe connection control on the drill floor and workover sites. Both tubing and casing hydraulic tongs adopt robust alloy steel body structures and heat-treated jaw dies, providing high clamping rigidity and wear resistance. Equipped with hydraulic drive systems and integrated backup tong assemblies, they realize synchronous clamping, high-speed spinning and precise torque tightening.
Tubing Tongs feature lightweight and flexible design with sensitive speed regulation, suitable for precise connection control of small-size tubing threads and premium connections. Casing Tongs adopt reinforced heavy-load gearboxes and large-opening jaw structures, supporting ultra-high torque output to cope with large casing thread friction and rigid connection requirements. Both series support real-time torque monitoring, stepless speed adjustment and stable hydraulic power output, fully complying with API 7K industrial specifications.
High connection accuracy with digital torque control, effectively preventing under-torque, over-torque and thread galling, ensuring qualified threaded connection quality. Hydraulic fully automatic operation greatly reduces manual labor and avoids high-risk manual tong operations on the drill floor. Strong structural durability and impact resistance, adapting to long-duration continuous operation under muddy, dusty and high-load oilfield conditions. Compact and easy-to-install structure, convenient for transportation, field assembly and daily maintenance, lowering operational and maintenance costs.
Hydraulic Tubing Tongs are widely used for running and pulling production tubing, completing tubing thread make-up and break-out, and performing well workover, well cleaning and downhole tool assembly operations. Hydraulic Casing Tongs are mainly applied in casing running operations, surface casing and technical casing connection tightening, large-diameter pipe string disassembly, and prefabrication of casing strings. Both tong series serve full-range oilfield scenarios, including onshore vertical, directional and horizontal well drilling, as well as offshore operations on jack-up rigs, semi-submersible platforms and drillships. They are standard essential equipment for modern intelligent and safe drilling and completion engineering.
