The hydraulic drill pipe power tongs are essential wellhead tools for oil and gas drilling operations, widely used in offshore and onshore drilling and well servicing tasks. These power tongs are designed to safely and efficiently make up and break out drill string connections, offering significant labor savings and improved operational efficiency. The open-throat design allows for easy disengagement from the drill string, providing high mobility and versatility.
This series of power tongs combines the functions of a torque wrench and a spinner in one unit, replacing the need for manual tongs, catheads, and rotary ropes. The power tongs meet the SY/T5074 standard, ensuring reliability and safety in various drilling conditions.
Key Features:
- Open-Throat Design: Allows for easy disengagement from the drill string, enhancing mobility.
- Integrated Functions: Combines torque and spinning functions, replacing manual tongs and other tools.
- Compliance with SY/T5074 Standard: Ensures safety and reliability in drilling operations.
- Hydraulic and Pneumatic Operation: Provides efficient and powerful operation with adjustable torque and speed settings.

Applications and Role
The hydraulic drill pipe power tongs are designed for efficient and safe handling of drill pipes, casings, and tubing in oil and gas drilling operations. By combining torque and spinning functions in a single tool, these power tongs streamline the makeup and breakout processes, reducing manual labor and enhancing operational efficiency. The open-throat design provides high mobility and easy disengagement, making them ideal for both offshore and onshore drilling activities.
SMKST II Series tongs are upgraded versions of the original power tongs. They feature an additional DS lifting device for frequent height adjustments, enhancing safety and ease of use.
SMKST III Series tongs are further improvements. They are designed for fixed installation on specialized drilling platform tracks, allow for remote control and automation, and are particularly suited for mechanized operations in smaller rig areas.
