Tension control system ensures integrity of bolted joints

Tension control system ensures integrity of bolted jointsJames Walker RotaBolt and Hytorc are launching what is described as the world's first fully integrated tension control system for bolted joints – Integrity. This 'fool-proof' system quickly and easily installs fasteners at the correct design tension without even having to remove the tool from the bolt during the process. Together the innovative tool and fastener ensure that the correct tension is achieved every time and then maintained throughout the life of the bolted joint.

Failures of critical bolted joints can be disastrous and over 90 per cent of all failures can be attributed to insufficient bolt tension at installation. The two companies have developed Integrity as an integrated system with the science of tension control at its heart. They say that it is the world's first tightening tool to incorporate the technology used during the production of RotaBolt tension control fasteners within the specially developed checking device. The tool automatically senses when the special cap has locked on top of the fastener and then immediately cuts off the hydraulic tightening power.

Rod Corbett from James Walker RotaBolt states: "Integrity is set to become the industry standard wherever reliability and safety are of paramount importance in bolted joints. It is optimum bolt tightening - simple, accurate, fast and fool-proof."

The new Hytorc tool, with its accuracy and capability, coupled with RotaBolt's tension control and 100 per cent load test calibration, has resulted in what the companies say is the most advanced technology-led system in the world. It delivers the speed and flexibility of fully integrated hydraulic torque tightening, combined with tension control accuracy to +/-5 per cent.

As a complete system, it quickly and simply installs to the correct design tension and then monitors and maintains that tension throughout the life of the bolted joint through the control technology incorporated in each RotaBolt.
