Combined Pigs are specialized tools used in pipeline inspection that utilize multiple inspection technologies to provide a comprehensive assessment of the pipeline's condition.

These pigs combine the features of multiple inspection tools, such as ultrasonic testing, magnetic particle testing, and caliper pigs, to provide a more complete picture of the pipeline's condition.

The use of combined pigs allows for multiple types of inspection to be performed during a single pass through the pipeline. This can be particularly useful in cases where multiple types of damage or defects are present, as the pig can be used to identify and analyze each type of damage in turn. This can help to reduce the number of pipeline inspections required, as well as the overall time and cost of the inspection process.

Combined pigs can also be equipped with advanced sensors and data collection systems, which allow for real-time data analysis during the inspection process. This data can be used to identify potential problems or areas that require further investigation, as well as to track changes in the pipeline's condition over time.

Overall, combined pigs are a valuable tool for pipeline inspection, as they provide a comprehensive assessment of the pipeline's condition and allow for multiple types of inspection to be performed during a single pass. They can help to reduce the overall time and cost of the inspection process, as well as provide valuable data that can be used to track changes in the pipeline's condition over time.
