Torque Verification
IRON ROUGHNECK
TORQUE TESTING
The IRTT is used to regularly verify the torque output of an Iron Roughneck. This ensures that torque output is accurate, and reduces damage to rotary shoulder connections during make-up. Regular verification can prevent downtime, equipment failure, and extend the service life of your drill pipe.
