Hydraulic Riser Torque Wrenches Series

Winner ASME Woelfel “Distinguished Innovation Award” OTC 1999

The patented RT-Series tool combines hydraulic speed and torque wrench technology to make up and break out subsea riser bolted flanges. With the simple push of a button, the apparatus spins the nut down at high speed and completes the torque to a preset limit; it can also reverse the procedure by spinning the nut up at a similar rate. Winner of the ASME Woelfel Distinguished Innovation Award at the 1999 Offshore Technology Conference, the RT-Series has recorded make-up and break-out times of less than two minutes per flange with torque capacities up to 38,500 pounds.
