The Project

Metalogic was awarded the Primary NDT Contract for Capital Power’s construction of Hitachi’s 450 Megawatt Supercritical coal-fired boiler, Keephills 3 (K3). In addition to requiring a turnkey service provider, the primary reason for the award was based on “Metalogic’s track record of reducing construction schedule bottlenecks and increasing asset reliability”.


Metalogic provided the following NDT services:


  • Radiography
  • Positive Material Identification
  • Magnetic Particle Testing
  • Liquid Penetrant Testing
  • Hardness testing
  • Q.A., Q.C.
  • Data Management


In addition to conventional NDT services, Metalogic’s proprietary ultrasonic technology MetaPhase™ was applied to the following assets:

  • Boiler Tubing
  • High-Energy Piping
  • Process Piping
  • Structural Steel
  • Storage Tanks
  • Mine Equipment

Project Highlights

Project Firsts:

  • Replaced x-ray as the primary weld inspection technique.
  • High temperature (400deg) phased-array inspection on High-Energy Piping.
  • Inspection of rifled tubing with phased-array.
  • Inspected Water Wall Tubes 100% (tangent) with phased-array.


Project Impacts:

  • Eliminated construction trade bottlenecks by removing x-ray windows.
  • Reduced risk of failure through increased P.O.D. on critical defects (cracks and non-fusion).
  • Reduced repair rates through real-time inspection feedback to welders and innovative E.C.A.
  • Significant overall reduction in construction costs.
  • NDT services came in under budget.
