The TQ340/35YA casing power tongs are specialized hydraulic power tools for oil drilling and well workover operations. Specifically designed for casing threading and unthreading, they replace traditional manual operations with powerful hydraulic force, providing strong support for downhole workers and significantly improving the efficiency and quality of casing connection operations. They are an indispensable core piece of equipment in oil and gas field drilling and workover projects.
Product Application
The TQ340/35YA casing power tongs are primarily used throughout the entire oil well casing installation process, precisely tightening and loosening casing threads. The product completely replaces manual operation with hydraulic power, significantly reducing the labor intensity of on-site workers, while also minimizing the risk of human error through its structure. Throughout the casing threading and unthreading process, it provides stable control of the casing string, effectively improving operational safety and overall construction efficiency, and providing reliable assurance for oil and gas well casing connections.
Structural Features and Core Performance
This power tong adopts an innovative design combining hydraulic drive and mechanical gear shifting, adapting to various casing sizes from approximately 5½” to 13⅝”, covering the needs of conventional oil and gas well casing operations. Equipped with open double rotating jaws, it offers stable clamping and convenient opening and closing. The overall structure is robust and durable, impact-resistant and wear-resistant, easily handling complex drilling conditions. It also supports an optional torque control display system, allowing precise control of the tightening torque to ensure the sealing and reliability of the casing connection. The product design strictly adheres to industry standards such as SY/T5074 and API Spec 7K, ensuring efficient, stable, and reliable operation throughout the entire process.
Core Technical Parameters
- Low Speed Gear: Maximum torque up to approximately 35,000 N·m (approximately 25,814 ft-lbs) under normal operation, meeting the heavy-duty coupling and uncoupling requirements of large-size casing and deep wells.
- High Speed Gear: Maximum torque approximately 4,800 N·m (approximately 3,540 ft-lbs), suitable for rapid operations with small-size casing and shallow wells, improving construction efficiency.
- Flexible Speed Adjustment: Different gears allow for flexible adjustment of head speed, adapting to various operating rhythms, balancing heavy-duty performance and operational efficiency.
- Portable Design: Overall size and weight adapted to field operation needs, supporting the carrying of spare clamps to cope with unexpected situations and ensure construction continuity.
