Cast iron pipeline inspection is a specialized process for assessing the structural integrity, corrosion state, and remaining service life of cast iron pipes.

Cast iron pipeline inspection is a specialized process for assessing the structural integrity, corrosion state, and remaining service life of cast iron pipes — commonly used in water distribution, sewage systems, and legacy gas networks. Cast iron is particularly prone to graphitic corrosion, internal scaling, and joint degradation, making regular inspection critical for safe operations.

Inspection methods include visual assessment, ultrasonic testing, magnetic particle inspection, and advanced non-invasive techniques like Current Magnetometry Inspection (CMI). CMI enables aboveground inspection of buried cast iron pipelines — detecting wall loss, corrosion patterns, and structural anomalies without excavation.

EMPIT’s CMI technology is proven for ferromagnetic materials including cast iron, grey iron, and ductile iron, providing high-resolution data for pipeline condition assessment, risk-based maintenance, and asset management decisions.
