Our recently completed projects are a testament to our ability to consistently provide clients with a leak-free startup for turnaround, through the Controlled Bolting Services we offer:

As part of our Controlled Bolting Services, we also provide bolt tensioning. 

Bolt Tensioning is the process of stretching the bolt by applying an axial load directly onto the bolt. Bolt tensioning is accurate and offers time-saving on larger flanges. It is commonly used for bolt sizes 1.1/2” diameter and above.

Generally, 50% of studs are tensioned simultaneously applying an even and accurate load on the gasket, thus providing the best chance for an effective long-term seal. We stock Bolt Tensioners to cover up to 4” diameter bolts. We provide bolt load calculations and flange stress analysis.
