Modeling of pipeline corrosion control by cathodic protection, has been made. It can augment the design process and present a number of experimentally determined factors that should be applied to present modeling code development. To improve the computational approach to cathodic protection system design for bare and coated pipe, different factors e.g. environment resistivity, different coating materials, current density, location of anode and attenuation potential along the pipe must be taken into account. It is found that polyethylene tape coating is more proper than other coatings which act to electrically isolate the pipeline from its surroundings, thus cutting off the return electron path and preventing the formation of a corrosion cell. Coatings protect more than 99% of the pipe surface. Increasing the environment resistivity decreases corrosion rate and current density. Moreover, location of anode can be controlled by potential and current density, which has a major effect on corrosion rate of partial cathodic protection. Environment resistivity affects limiting current density which is found to be important.

Details the proper methods to assess, prevent, and reduce corrosion in the oil industry using today's most advanced technologies This book discusses upstream operations, with an emphasis on production, and pipelines, which are closely tied to upstream operations. It also examines protective coatings, alloy selection, chemical treatments, and cathodic protection—the main means of corrosion control. The strength and hardness levels of metals is also discussed, as this affects the resistance of metals to hydrogen embrittlement, a major concern for high-strength steels and some other alloys. It is intended for use by personnel with limited backgrounds in chemistry, metallurgy, and corrosion and will give them a general understanding of how and why corrosion occurs and the practical approaches to how the effects of corrosion can be mitigated. Metallurgy and Corrosion Control in Oil and Gas Production, Second Edition updates the original chapters while including a new case studies chapter. Beginning with an introduction to oilfield metallurgy and corrosion control, the book provides in-depth coverage of the field with chapters on: chemistry of corrosion; corrosive environments; materials; forms of corrosion; corrosion control; inspection, monitoring, and testing; and oilfield equipment. Covers all aspects of upstream oil and gas production from downhole drilling to pipelines and tanker terminal operations Offers an introduction to corrosion for entry-level corrosion control specialists Contains detailed photographs to illustrate descriptions in the text Metallurgy and Corrosion Control in Oil and Gas Production, Second Edition is an excellent book for engineers and related professionals in the oil and gas production industries. It will also be an asset to the entry-level corrosion control professional who may have a theoretical background in metallurgy, chemistry, or a related field, but who needs to understand the practical limitations of large-scale industrial operations associated with oil and gas production.

Corrosion, Volume 2: Corrosion Control deals with corrosion and corrosion control. Topics covered range from the design and economic aspects of corrosion to cathodic and anodic protection; pretreatment and design for metal finishing; protective action of metallic coatings; and methods of applying metallic coatings. Corrosion testing, monitoring, and inspection are also considered. This volume is comprised of 13 chapters; the first of which provides an overview of corrosion control, with emphasis on the classification of practical methods of corrosion control. Attention then turns to the economic aspects of corrosion; how corrosion control is implemented in chemical and petrochemical plants; and design considerations to prevent corrosion in buildings and structures. Design in marine engineering and in relation to welding and joining is also discussed. The chapters that follow focus on the principles and practical applications of cathodic and anodic protection; chemical and mechanical pretreatments for metal finishing; and design for corrosion protection by electroplated and paint coatings. Chemical conversion coatings and miscellaneous coatings such as vitreous enamel coatings are also considered. Finally, this book describes the conditioning of the atmosphere to reduce corrosion. Tables and specifications as well as terms and abbreviations are included. This book will be of value to students as well as workers and engineers involved in corrosion and corrosion control.

Underground pipelines transporting liquid petroleum products and natural gas are critical components of civil infrastructure, making corrosion prevention an essential part of asset-protection strategy. Underground Pipeline Corrosion provides a basic understanding of the problems associated with corrosion detection and mitigation, and of the state of the art in corrosion prevention. The topics covered in part one include: basic principles for corrosion in underground pipelines, AC-induced corrosion of underground pipelines, significance of corrosion in onshore oil and gas pipelines, numerical simulations for cathodic protection of pipelines, and use of corrosion inhibitors in managing corrosion in underground pipelines. The methods described in part two for detecting corrosion in underground pipelines include: magnetic flux leakage, close interval potential surveys (CIS/CIPS), Pearson surveys, in-line inspection, and use of both electrochemical and optical probes. While the emphasis is on pipelines transporting fossil fuels, the concepts apply as well to metallic pipes for delivery of water and other liquids. Underground Pipeline Corrosion is a comprehensive resource for corrosion, materials, chemical, petroleum, and civil engineers constructing or managing both onshore and offshore pipeline assets; professionals in steel and coating companies; and academic researchers and professors with an interest in corrosion and pipeline engineering. Reviews the causes and considers the detection and prevention of corrosion to underground pipes Addresses a lack of current, readily available information on the subject Case studies demonstrate how corrosion is managed in the underground pipeline industry
