EMAT bolt axial force testing system

ORIBOLT X bolt axial force testing

The ORIBOLT X system by ORISONIC measures the real axial force in each installed bolt, without contact and without disassembly, so a bolting campaign is directed only at the joints that need it.

Key points

Direct measurement of the absolute bolt axial force (preload). Loose and broken bolts identified fast, no more relying on torque.

Greatly reduces maintenance time, labour and downtime costs.

EMAT technology, unlike piezoelectric ultrasound: no grinding, no couplant, no adhesive patches. Simple to use, low cost.

Contributed to drafting GB/T 43232-2023, Ultrasonic measurement method for axial stress of fasteners.

What you get from WindX UCP

  • We can test a complete flange in one visit and report the axial force of each bolt, showing under-tightening and missed bolts.
  • A record that follows the turbine. Each measurement is stored per bolt, so the next inspection shows the trend.
  • WindX UCP is the authorised partner for wind power applications

Full specifications, series tables and test reports are in the catalogue.
