Product Overview
The Manual Tong produced and sold by our company Huichi Petro is a key manual tool for tightening or unscrewing the connection threads of drill pipes, casings, tubings, etc. in oilfield drilling operations. It provides high torque output through the lever principle to ensure the firmness of the pipe connection. Its high-strength alloy material and ergonomic design have strong clamping force and torque output, which can adapt to the operational needs of land drilling, well repair and complex formations.

Core functions
- Advanced clamping mechanism: Equipped with advanced clamping mechanism, the clamping performance is reliable, and it can stably clamp drilling equipment such as drill pipes and tubings to prevent sliding or falling off during operation, ensuring safe operation.
- High torque output: The lever-type structure design can achieve 3000-15000 lbf·ft (about 4067-20337 N·m) torque by a single operator to ensure the sealing of the pipe connection.
- Multi-specification adaptation: The pliers are adjustable, suitable for drill pipes, casings and tubing outer diameters from 2-3/8" to 20", supporting API standards and special buckle types.
- Durable and impact-resistant: Integral forged pliers + surface hardening treatment, anti-deformation, wear-resistant, and suitable for high-intensity repeated operations.
- Safe operation: Anti-slip handle + self-locking ratchet design to avoid slipping or rebound during operation, reducing the risk of injury.

Product advantages
- High cost-effectiveness: Compared with some automated tongs equipment, manual tongs are more affordable and have low maintenance costs.
- Strong reliability: Manual tongs do not rely on complex electronic control systems, are not affected by factors such as power supply and electronic component failure, and can still operate stably in harsh working environments, with extremely high reliability.
- Super durability: Overall forging process + local quenching, the service life is 3 times longer than that of ordinary tongs.
- Flexible and efficient: The adjustable tongs head can quickly adapt to different pipe diameters, saving tool replacement time.
- Safety and compliance: Passed API 7K certification, adapted to international mainstream drilling safety standards.
- Customized service: Supports non-standard pipe diameters, torque enhancement and anti-sulfur material customization to meet special working conditions.
- Convenient operation: The design of the equipment conforms to the principles of ergonomics, and the length and shape of the handle have been carefully optimized. Operators can easily apply force when using it, reducing labor intensity.
