Hydrostatic Testing, Corrosion, and Microbiologically Influenced Corrosion ─ A Field Manual for Control and Prevention

Hydrostatic testing assesses pressure vessels, such as pipelines, for strength and leaks. It involves filling a vessel with liquid and pressurizing the vessel to a set test level. While an important procedure for industries, residual liquid from the test can cause issues with vessel corrosion, particularly microbial corrosion. This manual discusses how test liquid must be selected, corrosion by bacteria ought to be controlled, and the possibility of leakage can be eliminated. It does not teach how to conduct a hydrotest, but helps the reader evaluate the quality of a hydrotest already conducted in terms of use of oxygen scavenger, biocide testing, inhibitor addition, and water quality.

Reza Javaherdashti, PhD, holds a double degree in materials science and metallurgical engineering. He has more than 20 years of industrial and academic experience. In addition to various research papers and root cause analysis reports, Dr. Javaherdashti has authored several reference books on corrosion. He is an American Society of Mechanical Engineers (ASME)-approved trainer and has designed and executed many international industrial workshops. Furthermore, he has been involved in many consulting and problem-solving activities around the globe and is also a corrosion advisor to internationally renowned companies. Dr. Javherdashti is a veteran member of various? well-reputed international corrosion societies such as the National Association of Corrosion Engineers (NACE).

Farzaneh Akvan has a background in physical chemistry and electrochemistry. She holds an MSc degree, and her interests include corrosion management, chemical management, and electrochemistry and its application in corrosion control. She was selected as the Best Young Researcher in Europe in 2010 for her research on cathodic disbondment (she received the award from the Gubkin Russian State University of Oil and Gas). Akvan has worked at the internationally renowned company SGS as a senior officer for inspection? of chemicals and materials. In addition to industrial experience, she is also a long-standing member of the Iranian Young Researchers and Elite Club. Akvan has served as executive manager for the Iranian Corrosion Association. She is currently working as a consultant to the oil and gas industries as a senior inspector and corrosion advisor and as a lecturer on the management of the chemicals used for water treatment and corrosion. She has authored several publications on corrosion management and the link between future studies and corrosion management. Akvan is also a member of the International Electrochemistry Society.
