The Weatherford 16-25 hydraulic casing tong provides 25,000 ft-lb (33,900 N•m) of torque capacity for running and pulling 6 5/8- to 16-in. casing. At the heart of this versatile and lightweight tong is a unique gated rotary that completely encircles the casing. This design provides as many as seven
contact points that distribute gripping forces over a greater area than conventional tong designs, ensuring a positive grip without damaging the casing. The optional integral free-floating backup helps
to ensure proper connection makeup and long- term wellbore integrity.
Applications
• Running and pulling 6 5/8- to 16-in. tubulars
Features, Advantages, and Benefits
• The tong design handles high-torque requirements without the case body distortion problems that
plague many other tongs, so it reduces equipment repair costs and increases efficiency.
• The versatile and lightweight tong is easy to operate, which saves time and enhances personal safety.
• The tong design allows the operator to switch between makeup and breakout modes by moving a single
pin, which saves time and increases operational efficiency.
• The optional hydraulic free-floating backup virtually eliminates shearing and bending when making up
or breaking out connections, reducing casing deformation that can affect long-term wellbore
integrity.
• The hydraulic door interlock prevents tong operation while the doors are open or unlatched, providing
additional safety.
• An optional lift cylinder quickly adjusts to varying connection heights, making this versatile tong
easily adaptable for different stump heights.
• Multiple contact points distribute gripping forces, preventing damage to casing and the need for
costly repairs.
• Compatibility with Weatherford JAMPro™ torque control systems enables real-time monitoring of torque,
turns, and speed.
