Underground Pipeline Corrosion


Book Description

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

Review of the Bureau of Reclamation's Corrosion Prevention Standards for Ductile Iron Pipe


Book Description

Ductile iron pipe (DIP) was introduced about 50 years ago as a more economical and better-performing product for water transmission and distribution. As with iron or steel pipes, DIP is subject to corrosion, the rate of which depends on the environment in which the pipe is placed. Corrosion mitigation protocols are employed to slow the corrosion process to an acceptable rate for the application. When to use corrosion mitigation systems, and which system, depends on the corrosivity of the soils in which the pipeline is buried. The Bureau of Reclamation's specification for DIP in highly corrosive soil has been contested by some as an overly stringent requirement, necessitating the pipe to be modified from its as-manufactured state and thereby adding unnecessary cost to a pipeline system. This book evaluates the specifications in question and presents findings and recommendations. Specifically, the authoring committee answers the following questions: Does polyethylene encasement with cathodic protection work on ductile iron pipe installed in highly corrosive soils? Will polyethylene encasement and cathodic protection reliably provide a minimum service life of 50 years? What possible alternative corrosion mitigation methods for DIP would provide a service life of 50 years?

Corrosion


Book Description

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.
