Inline Inspection (ILI) Pipeline Pigging

How do you ensure the safety and integrity of your pipelines? One of the most effective and comprehensive methods involves pipeline pigging (or ILI) – a preventative maintenance operation for identifying pitting corrosion and other defects in your pipelines.

Pipeline pigging refers to the process of sending a device known as a pig, or ILI tool, through a pipeline. The pig travels with the flow of the product to provide information on the condition of all relevant materials and the extent and location of any problems, such as pitting corrosion or other damage.

At Corrosion Control Engineering we can help you maintain the integrity of your pipelines by detecting potential issues early.

In-line inspections scan for issues that may present evidence of general pitting or other corrosion forms such as:

Innovative Scanning Technologies

Inspection methods include magnetic flux leakage (MFL) and ultrasonics (UT). MFL is a method where a strong magnetic flux is induced into the pipeline wall. Sensors then pick up any leakage of this flux and the extent of the leakage indicates a flaw in the pipe wall. Material loss from the pipe wall, for example, will cause flux leakage that should be identified by the pig’s sensors. All defects are then logged.

Ultrasonic inspection is a direct measurement of the wall thickness and can identify cracks in the pipe wall. A transducer emits a pulse of ultrasonic sound that travels at a specific speed. The time taken for the echo to return to the sensor is a measurement of the thickness of the pipe wall. This techniques requires a liquid medium for the pulse to travel.
