CASING POWER TONG

TECHNICAL SUMMARY

TQ Series Casing Power Tongs are specialized for large-diameter casing makeup/breakout. Featuring hydraulic drive, high-torque output (up to 500000N·m) and adjustable clamping jaws, the TQ300 Series fits 13⅜-20” casings for onshore deep wells, while the TQ500 Series adapts to 20-24½” super-large casings with reinforced frame. Equipped with torque monitoring and anti-slip inserts, they ensure stable, damage-free operations in offshore and ultra-deep well scenarios.
