Pipeline debris — including rust, scale, sand, wax deposits, and foreign objects — accumulates inside pipelines over time and poses significant challenges for both pipeline.

Pipeline debris — including rust, scale, sand, wax deposits, and foreign objects — accumulates inside pipelines over time and poses significant challenges for both pipeline operations and inspection. Debris buildup can reduce flow capacity, damage seals and valves, and create conditions for under-deposit corrosion.

For inline inspection (ILI), debris is a critical concern: accumulated material can block smart pigs, damage sensor arrays, or produce false readings. In many cases, excessive debris makes a pipeline unpiggable until cleaning runs are completed.

Alternative inspection approaches that do not require internal pipeline access can bypass debris limitations entirely. EMPIT's Current Magnetometry Inspection (CMI) assesses pipeline condition from the surface — detecting corrosion, wall loss, and integrity threats regardless of internal cleanliness. This makes CMI particularly valuable for aging pipelines, pipelines with known debris issues, or systems where cleaning operations are impractical.
