NEW EDITION! This book provides an extensive update on the second edition with general coverage of the wide field of corrosion control. It is designed to help readers being initiated into corrosion work and presents each corrosion process or control procedure in the most basic terms. Since the first edition was published in 1970, there have been major advances and changes in the technologies used to combat corrosion damage. Third Edition. NACE, 2018.
Various integrity-management projects associated with the oil and gas industry have demonstrated that corrosion engineering by itself cannot effectively mitigate post-commissioning corrosion. Many corrosion-related failures, leaks, and near misses are not caused by obsolete, inadequate, or erroneous corrosion engineering designs or applications, but are promoted by other shortcomings. Inadequate consideration of other factors or parameters—owing to negligence, ignorance, complacency, incompetence, or a combination of these—can adversely influence the overall integrity management of an asset.
This book is based on the author’s experience in the oil and gas industry. However, the discussions, guidelines, and principles presented can be used or applied with minimal changes or modifications, if necessary, to all other industries.
Since the 1980s, a range of duplex stainless steels (DSSs) has been developed that have higher alloy content, and therefore greater corrosion resistance and strength. The commonly used DSSs have good corrosion resistance in a wide range of environments and excellent resistance to stress corrosion cracking (SCC). Their high strength and hardness also gives them excellent resistance to both erosion corrosion and cavitation. There are also cast versions of many of the duplex compositions and these have seen extensive use for pumps, valves, and other equipment.
