bolted joint inspections.

monitoring and corrective adjustments of critical flange bolts

Wherever the integrity of critical bolted joints cannot be left to "chance", hevii is engaged by clients to provide "certainty". Using specialised equipment and techniques, our Technicians, some with over 25 individual years of experience in this unique field, travel globally to remote sites to ensure proper bolt stress ("tightness") of crucial structures and equipment by determining existing preload and then properly adjusting any fasteners found found to be out of tolerance.
