Preconfigured bolts
JOINT DESIGN
Complex procedure to determine torque tightening parameters required in order to achieve design preload. Design variables an inaccuracies are inherent in this process.
INSTALLATION & TIGHTENING
Simply install bolts and torque until monitor indicates “OK”. Design preload has automatically been achieved and verified.
INSTALLATION & TIGHTENING
Bolts are installed and torque tightened usually using tooling designed to indicate torque, not tension (preload). Installation routine requires repetition to verify torque values have been achieved. However indirect torque values are not as accurate direct preload measurement. Immediate loss of preload associated with joint settlement cannot be identified.
JOINT LOCATION AND PRELOAD MONITORING
Bolt location and preload data is transmitted automatically to remote user. No equipment shutdown required.
JOINT LOCATION AND PRELOAD MONITORING
Field service evaluation of joints required, both costly and dangerous. Also requiring equipment shutdown.
INSPECTION
Inspection takes place automatically and proactively, at pre-programmed intervals. Bolt sends a signal when preload level trigger is reached.
INSPECTION
Joint inspection using torque check method is inaccurate and unreliable. Friction conditions in the joint may have changed since first check. As with monitoring, equipment shutdown is required and inspection “at the joint” is costly and dangerous.
DATA RECORDING
Data is acquired and stored automatically
DATA RECORDING
Field Service evaluation and inspection reports are used to create time consuming reports that are inherently still lacking accuracy.
JOINT FAILURE
Risk of joint failure is minimized since condition based maintenance programs can now be introduced to bolted joints. Acquired joint data can be used for many types of analysis, including design and maintenance optimization.
JOINT FAILURE
Failures still occur since condition based maintenance is difficult, inspection results are inaccurate and predictive failure signals are not generated or captured.
