CAPITAL POWER KEEPHILLS 3 SUPERCRITICAL BOILER

October 3, 2017

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.
