Smart PIGs are intelligent by design and equipped with a battery, a variety of sensors and a GPS system to map data when performing their inspections.
A PIG is inserted into and travels through the length of the pipe collecting data on potential hazards including external and internal defects, corrosion and structural integrity of the pipeline systems.
A key function of PIGs is preventing problems before they happen - for example, identifying early signs of corrosion so that repairs can be made well before a leak can occur.
Smart pigging provides a number of advantages over traditional forms of pipeline inspection:
- It allows pipelines to be cleaned and inspected without having to stop the flow of product
- It also allows the a pipeline to be completely inspected without having to send inspectors down its entire length
- It provides cleaning and inspection services at the same time, saving companies both time and money
Today, pipeline pigging is used during all phases of the life of a pipeline.
