01 The Threat Vector

During a routine inspection, site engineers suspected material degradation in the high-stress zones of the runner blades (near the root). However, traditional visual inspections failed to confirm the extent. The unit was operating under a "blind" risk of blade separation due to Stress Corrosion Cracking (SCC), which propagates internally before breaking the surface.

> RISK DETECTED: INTERNAL MICRO-FRACTURES
> CONSEQUENCE: CATASTROPHIC RUNNER FAILURE

02 Tactical Execution

We deployed the AnoHUB NDT Matrix to look beneath the surface:

  • Phased Array Ultrasonic (PAUT) Utilized multi-element probes to scan deep into the blade structure, detecting sub-surface flaws and measuring the exact depth of crack initiation.
  • Magnetic Particle (MPI) Applied fluorescent MPI under UV light to identify surface-breaking micro-fractures in ferromagnetic stress zones invisible to the naked eye.
  • Repair Blueprint Mapped fatigue zones and provided a precise welding and heat-treatment blueprint to arrest crack growth without compromising the hydraulic profile.
