TORQUE TESTING (IRTT)
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.
At ProTorque, our philosophy, based on historical data, believes that all Tubular Connections should use CATM. There are a variety of issues that could occur while making up different connections, most of which cannot be seen without a graphical representation.
This service prevents the running of damaged or incorrectly made-up casing and tubular strings. CATM eliminates leaks during the fracturing (Frac) process and ensures the correct performance and isolation for your packer system. This isolation reduces, if not completely eliminates, the environmental risks when carrying out this process.
CONSEQUENCES OF INCORRECT MAKE-UP
A variety of factors can cause an Iron Roughneck to apply errant torque such as mistaken system settings, jaw alignment issues, temperature variations or plumbing leaks. Any of these factors can go undetected by simple pressure checks or other indirect diagnostics. There is only one way to ensure an Iron Roughneck is delivering correct make-up torque to your connections – by directly measuring the torque being applied from within its jaws.
FULL-SCALE TORQUE CAPACITY
65,000 – 150,000 ft/lbs (88,000 – 203,000 Nm)
6.63 – 9.5” (168.2 – 241.3 mm)
9.25 – 12.75” (235 – 323.9 mm)
17 – 4 PH Stainless Steel
150 – 250 lbs (70 – 115 kg) dependent on torque range
30 – 32” (762 – 812.8 mm)
Since a direct (not derived or estimated) torque measurement is captured by the IRTT, it removes additional calculations, correlations or guesswork. The IRTT directly measures the make-up torque that is being delivered to your joint connections. Measurements captured by the IRTT allow an operator to adjust the Iron Roughneck set point to maximize the accuracy of the make-up torque delivered.
The IRTT measures the make-up torque being applied by an Iron Roughneck to the joint connections. This allows an operator to adjust the Iron Roughneck set point to maximize the accuracy of the make-up torque delivered, preventing “back-off” or “twist-off” events, saving approximately $400,000 per adverse event.
