Ductile iron pipeline inspection assesses the structural integrity, corrosion state, and remaining service life of ductile iron (DI) pipes — widely used in water distribution, wastewater collection, and gas distribution networks. Unlike cast iron, ductile iron has greater tensile strength and flexibility, but remains susceptible to external corrosion, joint degradation, and graphitization.

Inspection methods include Current Magnetometry Inspection (CMI), ultrasonic wall thickness measurement, visual assessment, and magnetic particle testing. CMI is particularly effective for ductile iron because it provides aboveground, non-invasive inspection of buried DI pipelines — detecting corrosion, depth of cover, and geometry anomalies without excavation.

EMPIT has extensive field experience with ductile iron pipelines across water utilities worldwide, delivering high-resolution inspection data that supports asset management, rehabilitation planning, and regulatory compliance for aging water infrastructure.
