Pigging with multiphase corrosion inhibitors

摘要

Pigging has many useful purposes, including applying a corrosion inhibiting film to pipeline internals before layup. This helps protect the pipeline against corrosion and its associated problems while the pipeline sits unused. Traditional corrosion inhibitors only protect metal surfaces in direct contact with the inhibitor carrier fluid; however, Cortec's multiphase corrosion inhibitors, applied by pigging, offer enhanced protection by forming a protective molecular layer on all metal surfaces inside die pipeline, even those in the airspace above die fluid.
