Abstract
To meet business plan of any process plant, mechanical integrity and reliability of static equipment/piping is very important. This can be achieved by a good management system, which is placed to make sure that each element can be properly scheduled and completed at appropriate intervals. The corrosion management system is an integration of various corrosion control methods to achieve mechanical integrity and reliability of static equipment/piping.
The corrosion management system (the understanding, identification, measurement, monitoring, control and mitigation of different corrosion mechanisms within process plants) is integrated with other management systems playing a vital role in achieving excellence in plant integrity and reliability.
Management of change (MOC), Risk Based Inspection (RBI) and Integrating Operating Windows (IOW) are some of the essential components of a corrosion management system. Leak/failure reporting, tracking of failure analysis recommendations, pressure safety valve (PSV) analysis, record keeping and audit systems are also part of corrosion management system and need continuous improvement.
The main objective of a corrosion management system is to minimize the loss of containment of hydrocarbon and other critical process streams, which can be directly attributed to corrosion and have a detrimental impact on operation of process plants. Corrosion management also helps in developing the correct inspection plans and optimizing inspection intervals.
This paper describes various aspects and elements of a robust corrosion management system. It explains the integration of all these elements to enhance mechanical integrity of static equipment/piping in process plants.
