What is inline inspection?

Inline inspection (ILI) refers to the process of assessing the condition of pipelines from the inside using specialized inspection tools, often called 'smart pigs.' These tools travel through the pipeline and collect data on features such as metal loss, cracks, and deformations, helping operators identify potential issues before they become serious problems. Inline inspection is crucial for maintaining pipeline integrity, ensuring safety, and meeting regulatory requirements in the oil and gas industry. The data collected allows for more accurate maintenance planning and can extend the useful life of the pipeline.
