The Weatherford 14-50 high-torque casing tong provides 50,000 ft-lb(67,790 N\u2022m) 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.
\nThe 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
\npatented* PowerFrame\u00ae and PowerScope\u00ae systems.
\nApplications
\n\u2022 Running and pulling 6 5\/8- to 14-in. casing
\n\u2022 Making up and breaking out connections that require high torque
\n\u2022 Performing offline or moonpool casing makeup operations
\nFeatures, Advantages, and Benefits
\n\u2022 The tong with the hydraulic backup eliminates the need to use large manual rig tongs as backup when
\n running casing, thereby enhancing safety.
\n\u2022 The integral hydraulic backup grips pipe and couplings without crushing, which saves equipment repair
\n costs.
\n\u2022 The patented free-floating backup design virtually eliminates shearing and bending when making up or
\n breaking out connections. That reduces casing deformation, which can affect long-term wellbore
\n integrity.
\n\u2022 The tong is compatible with Weatherford JAMPro\u2122 torque control systems.
\n\u2022 The hydraulic door interlock prevents tong operation while the doors are open or unlatched to enhance
\n safety.
\n\u2022 The versatile tong design allows running of casing in the moonpool or offline on rigs that
\n accommodate these activities.
\n\u2022 The optional Micro-Grip\u00ae gripping system grips the casing fully, which minimizes damage to the
\n tubular surface that can lead to stress corrosion cracking, sulfide stress cracking, and associated
\n repair costs.
