NDE in Industry Why do NDE? Integrity Management Safety input into safety cases Life prediction input to corrosion and fracture mechanics calculations. Economics reduce unplanned downtime, - allow planned maintenance Damage Tolerant Design Process control and quality assurance Industrial plant New plant Inspection of new plant characterisation / fingerprint New plant and new designs Wind turbines Next generation of fossil plant New reactors (AP1000, pebble bed) Aerospace Composite materials in airframes and engines Oil and gas inherently safe design, normally unmanned installations NUI Materials Steel Stainless austenitic, ferritic, duplex etc. Zirconium Titanium, aluminium, Ni base super alloys, Single crystal castings Metal matrix composites Concrete / cements FRP and Polymers CRA clad Plastic lined Failure mechanisms /issues Fatigue crack Preferential corrosion at weld Intergranular corrosion 1mm long cracks in turbine blade Failure mechanisms Rolling defect X-ray CT image of composite showing waviness defect Stress corrosion cracking Difficult / hazardous environments Physical remoteness High temperature Chemical hazard Radiation Deep sea Arctic environment Buried Under insulation/fire-proofing Inside engines Remote inspection Structural health monitoring Measurement on load (reactor Pressure Vessels turbines etc) Aircraft and engines in flight Wind turbine spars Welds in boats Rails Floating Production Storage Offloading hulls/offshore jackets Pipelines Industry Needs in NDE Large area inspection Speed of inspection Early warning of changes Better characterisation of defects for use in life prediction Understand NDE capability and reliability Human factors Validation Better production of real defects Computer models Summary RCNDE represents a wide range of industries All need NDE Some common themes between industries but also specialised requirements Power Aerospace and Defence Nuclear Oil and gas Manufacturing
