Please, find below a small summary of the kind of projects:• i-bolt®: ultrasonic resident sensor for direct reading of the tension of the bolt.This allows us to know the preload of the joint at tightening and also during the life ofthe bolt with +-3% of accuracy. This could be a solution to reduce risks (leakages,…)in critical bolted joints.• Design of tightening strategies to assure optimal assemblies.• Computer joints simulations, real tests…• Validation of the bolted joint and the tightening strategy.• Projects to find failure root causes in bolted joints and proposal of solutions.2) Production of special bolts & stud bolts for critical applications. We manufacture special bolts & stud bolts for critical applications with high quality standards.
