Cathodic protection-Principles and Applications: This book will guide practicing corrosion engineers in the field about various CP applications and trouble shooting along with mitigating problems

The book will be relevant to the industries where cathodic protection is applied to carbon steel structures for protecting against corrosion. The pipelines in oil and gas industry find extensive application of Cathodic protection. This book will be an advantage to field technicians and engineers maintaining CP system and troubleshooting along with taking mitigation measures. Also, this book will find useful for process industries in cathodic protection of plant piping, storage tank bottoms and bullets. This will also be useful for middle level managers to direct field personnel for proper maintenance and monitoring and analyze data for correct assessment and taking mitigation measures. This book will also provide study material for preparation of all CP certification exam.. This book will provide the material for understanding the • Concept of corrosion and cathodic protection • Criteria for cathodic protection • Application of cathodic protection • Various field measurements such as potential and current , soil resistivity and polarization coupons • various tests such as coating conductance test and current requirement test • Various surveys such as CIPL, CAT and ACVG/DCVG survey and its interpretation • Stray current interference and its mitigation • AC corrosion and its mitigation • Telluric current and its mitigation • Sacrificial anode and ICCP system design with examples • Remoteness of ground bed and its calculation • Configuration of ground bed • Current distribution and attenuation • CP system for plant piping, storage tank bottom and bullets • Schedule for monitoring and SOP’s for monitoring • Trouble shooting and corrective measures • Live case studies with mitigation The purpose of writing this book is to impart knowledge about corrosion and cathodic protection required at field level in a simple language and style so that readers can understand the concept and apply in the field. The theory has been explained with practical examples to understand the concept better. The all important topics related to corrosion and cathodic protection like concept of corrosion and cathodic protection, types of cathodic protection, its principles and applications, field measurements and possible errors, coating integrity surveys and its analysis, design fundamentals and monitoring process and methodology have been explained. The fundamental doubts of field personnel will be cleared and it will help them effective maintenance and monitoring, trouble shooting and taking corrective measures in time. Also middle level engineers will be able to analyse the data and advise their field personnel to take right measures in the field. This is a new source of information in a very understandable language with practical point of view and considering field problems. The problems which are expected to be solved for readers are as follows: 1. All doubts about cathodic protection 2. The book content will provide them ready made solutions to all their CP problems and save their time and energy 3. The book is written on the basis of field experience and all field related issues are covered in line with the theoretical background. 4. Live case studies in the book will provide an opportunity to identify the nature of problems and its solutions. 5. SOP’s of monitoring CP parameters will guide readers for right approach to monitor 6. The ready made chart of trouble shooting will help them in trouble shooting and taking corrective measures Three key features and content in the book that will be most valuable to the reader will be as follows: 1. Criteria of cathodic protection and its significance 2. Field measurement of pipe to soil potential reading (ON and OFF) , its analysis and interpretation of result and corrective measures 3. Methodology of carrying out various CP surveys, its analysis and interpretation of result and corrective measures
