What is the purpose of pigging in Pipeline inspection?

Pigging in pipeline inspection is the process of using pipeline inspection instruments or “pigs” to clean, inspect, or maintain pipelines. The following are some of the main purposes of pipeline cleaning during pipeline inspection:

Inspection: Pigs can also be used to inspect the interior of pipelines for signs of corrosion, cracking, or other defects. Some pigs are equipped with sensors or cameras that can capture images or measurement results inside the pipeline, enabling operators to identify potential problems and plan repairs or maintenance.

Cleaning: A pipe cleaner can be used to remove debris, sediment, and other deposits inside the pipeline. This helps maintain the flow rate of the pipeline and reduces the risk of blockage or deceleration.

Maintenance: Pigs can also be used to perform various maintenance tasks on pipelines, such as applying coatings or inhibitors to prevent corrosion, or installing new pipe sections or components.
