Why on site?Bolt-tensioning provides the highest accuracy and uniformity for critical, high-pressure connections.
Scope of work
- ▸Hydraulic torque wrenches (±20–30% tolerance)
- ▸Bolt-tensioning: direct axial tensile force (±10%)
- ▸Heat exchangers, wind turbines, pressure vessels
- ▸Bolt-load calculations and documentation
- ▸For all common bolt sizes
- ▸Ultrasonic measurement of bolts
