Q3 3/8~12 3/4-75 Type B pliers:
The Q3 3/8~12 3/4-75 Type B drill pipe pliers (also known as Type B drill pipe pliers or manual drill pipe pliers) are essential tools for disassembling and reassembling drill pipe and joint threads during oil drilling and well workover operations. Specifically designed for threading and unthreading drill pipe and drill string joints during tripping and workover operations in oil and gas wells, these pliers feature interchangeable connectors and shoulder components for flexible adaptation to various drill pipe specifications. With high torque output and stable clamping, they provide safe and efficient thread disassembly and assembly for drilling operations, making them an indispensable core tool for wellhead operations on both onshore and offshore drilling platforms.
Key Product Features
- High Torque Output, High Efficiency: Rated torque up to 75kN·m, easily handles drill pipe thread assembly and disassembly, improving operational efficiency and shortening construction cycles.
- Multi-Specification Compatibility, One Clamp for Multiple Uses: Interchangeable connector components flexibly adapt to the full range of drill pipes from 3 3/8″ to 12 3/4″, reducing tool procurement costs.
- Rugged and Durable, Worry-Free Working Conditions: Constructed from high-strength alloy steel, impact-resistant and wear-resistant, suitable for various harsh drilling environments on land and at sea.
- Safe and Reliable, Protecting Drill Tools: Stable clamping structure prevents slippage, even clamping force avoids drill pipe damage, and ensures drill tool life.
- Easy Operation, Reduced Labor Intensity: User-friendly design, effortless operation, significantly reducing the labor intensity of on-site workers and improving operational safety.
