  • Chemical or abrasion treatment*;
  • Regrind/remachine*;
  • Seal replacement;
  • Hydraulic adaptor changeout*;
  • LOLER testing**;
  • Laser measurement and NDT */**;
  • Detailed inspection report
  • Third party inspection report**;
  • 1-year warranty against labour
  • Pressure test certificate and CE marking
  • Global DDP pick-up and delivery options**
*where required
**upon request

Traceable to National Standards, ACUTENSION has international testing facilities capable of pressure testing up to 400 MPa (60,000 psi). So no matter where your location, ACUTENSION can promise the swiftest possible turnaround, which can be configured to suit your outage or maintenance schedule. Please contact ACUTENSION today to ensure your hydraulic bolting equipment is in sound condition prior to plant shutdown or outage.
