Frequently Asked Questions (FAQ)
What is the function of the synchronized hydraulic backup tong?
The synchronized hydraulic backup tong works in tandem with the master tong to ensure reliable, flexible, and efficient combined make-up and break-out operations without causing damage to the pipe string or tubulars.
How do I select the correct universal die size for my power tong?
Die selection depends on the outer diameter (OD) of the drill pipe, casing, tubing, or sucker rod you are handling. Our power tongs come with universal die compatibility, offering a wide size range to support various operational requirements on the rig floor.
What are the benefits of the multi-speed gearbox in power tongs?
The integrated multi-speed gearbox allows operators to shift smoothly between high-speed mode (for rapid spinning and threading) and low-speed mode (for applying high final torque), significantly optimizing drilling efficiency and operational control.
Can the torque be digitally monitored and recorded during operation?
Yes, an advanced digital torque reader is available as an optional feature. It supplies accurate real-time monitoring, precise torque recording, and detailed data reporting to ensure compliance with tubular manufacturing standards.
What are the standard air pressure and hydraulic flow requirements?
Most drill pipe and casing power tong models operate efficiently within an air pressure range of 0.5–0.9 MPa (72–144 PSI) and require a working hydraulic flow rating typically between 110 L/min and 170 L/min, depending on the specific model specifications.
Is maintenance and adjustment easy for the integrated control systems?
Yes, the integrated brake and direction control mechanism is specifically engineered for quick and easy assembly, simplified routine adjustment, and convenient repair services, helping to minimize rig downtime.
