Pigging refers to the practice of using a device, known as a "pig," to travel through pipelines. A pigging program is a systematic and planned schedule of these operations. The primary purpose of pigging is to maintain the integrity and efficiency of pipelines. Different types of pigs exist, each designed for specific tasks. Cleaning pigs, for instance, remove debris, scale, and product residue that can accumulate over time. These build-ups can reduce flow rates and increase operational costs. Inspection pigs are equipped with sensors to detect flaws such as corrosion, cracks, or dents, which are crucial for safety and preventing potential failures. Batching pigs are used to separate different products being transported in the same pipeline, preventing contamination and ensuring product quality.

The implementation of a pigging program involves careful planning. Factors such as pipeline material, diameter, length, contents, operating pressures, and the specific objectives of the pigging operation are considered. A typical program will define the frequency of pigging, the type of pig to be used for each section or purpose, and the required procedures for deployment and retrieval. Regular pigging can significantly extend the lifespan of a pipeline, reduce maintenance costs, and ensure the safe and efficient transport of fluids or gases. The data collected from inspection pigs is vital for predictive maintenance and risk assessment.
