ETHER nde maxwell pect in-service pulsed eddy current inspection system

Pulsed Eddy Current (PEC) is an inspection technique for inspecting carbon steel objects such as pipes and vessels, without the need for contact with the steel surface. PEC can measure percentage variations in steel thickness through any non-conductive and non magnetic materials between sensor and surface such as air, insulation material, concrete, plastics, coatings, sea water and marine growth, paint, , deposits, oil, composite repairs, fireproofing, “scabs” aluminium sheeting and other nonmagnetic insulation covers; so ideal for Corrosion Under Insulation (CUI) applications. The MAXWELL PECT...

Application Case Studies PULSED EDDY CURRENT INSPECTION OF JETTY PILES The tidal zone of jetty piles are commonly protected by a ‘splash zone’ coating. When this gets damaged, severe corrosion can occur, potentially undermining the structural integrity of vital harbour installations. Conventional inspections are hampered by the thick splash zone coating and build up of marine growth. Pulsed Eddy Current Testing (PECT) measures remaining steel thickness without having to remove the coating, deposits and marine growth. The splash zone can be inspected by rope access techniques or from boats using...
