The Weatherford 14-50 high-torque casing tong provides 50,000 ft-lb(67,790 N•m) of torque capacity for running and pulling 6 5/8- to 14-in. casing. The tong has a unique gated rotary that completely encircles the casing to distribute gripping forces over a greater area and ensure a positive grip without pipe deformation and pipe marking. For added safety, the hydraulic door interlock prevents tong operation while the doors are open or unlatched.
The 14-50 casing tong is capable of fully mechanized remote operation or semi-mechanized operation. The tong is completely compatible with all Weatherford automated tong-positioning systems, including the
patented* PowerFrame® and PowerScope® systems.
Applications
• Running and pulling 6 5/8- to 14-in. casing
• Making up and breaking out connections that require high torque
• Performing offline or moonpool casing makeup operations
Features, Advantages, and Benefits
• The tong with the hydraulic backup eliminates the need to use large manual rig tongs as backup when
running casing, thereby enhancing safety.
• The integral hydraulic backup grips pipe and couplings without crushing, which saves equipment repair
costs.
• The patented free-floating backup design virtually eliminates shearing and bending when making up or
breaking out connections. That reduces casing deformation, which can affect long-term wellbore
integrity.
• The tong is compatible with Weatherford JAMPro™ torque control systems.
• The hydraulic door interlock prevents tong operation while the doors are open or unlatched to enhance
safety.
• The versatile tong design allows running of casing in the moonpool or offline on rigs that
accommodate these activities.
• The optional Micro-Grip® gripping system grips the casing fully, which minimizes damage to the
tubular surface that can lead to stress corrosion cracking, sulfide stress cracking, and associated
repair costs.
