Boltstress G5 Ultrasonic Bolt Tension Tool

Boltstress G5 Ultrasonic bolt tension measurement

Our core business is the measurement of bolt tension, we do this using either our own equipment or the clients

We both ensure that all bolting is tightened to the correct level before going live and then offering on-going re-monitoring to analyse joint performance in service.

Trained Bolt Torque Technician

Specialised technicians

We can measure using any brand of Ultrasonic Monitoring equipment.

Our Technicinas are fully trained in the use of the Boltstress G5, the Dakota Minimax, the Dakota MAX, the Boltscope 1 & 2, the Boltmike 1, 2 ∓ 3. the Norbar USM 1 & 2 and the Raymond Bolt Gauge

Optimum Tooling Real Measurements Joint Analysis Higher Availability Improved Procedures

Joint Analysis

We look at the joint geometry, joint conditions, pressures & temperatures; then we determine how to improve performance and propose the optimum solution

Real Measurements

Torque and Tension are estimations that go horribly awry in the wrong conditions. We measure what's really happening and implement corrective actions

Optimum Tooling

26 years experience has provided a wealth of knowledge. In the vast majority we can suggest tooling that is safer, quicker and lighter

Improved Procedures

Many standard bolting procedures are outdated or inaccurate. Using our real measurement results we develop faster, more accurate and safer procedures

Higher Availability

The real 'jewel in the crown', everything we do delivers Higher Availability. Shorter shutdowns & less shutdowns. A very high Return on Investment

Reduced Shutdown Durations
