🔶Pipeline pigging is the process of using a "pig" (a device inserted into a pipeline) to clean, inspect, or maintain the pipeline. Pigs are typically cylindrical or spherical devices that are pushed through the pipeline by fluid pressure or pulled by cable 🔸Some benefits of pipeline pigging include: - Improved flow efficiency - Reduced maintenance costs - Enhanced safety - Extended pipeline lifespan - Detection of potential issues before they become major problems. | Petroleum engineer
