Dr. Zamanzadeh (Dr. Zee) - NACE Fellow/Exova
Coating Dis-bondment, CP Shielding, AC Interference, and Localized Corrosion
There are many million miles of pipe lines many of them aging coated pipelines transporting natural gas, oil, and hazardous liquid in the North America next to aging AC transmission tower structures. Close to 50 percent of gas transmission and gathering pipe lines were constructed in the 1960’s and 1970’s, over fifty years old. Underground pipelines and transmission towers are aging and are at risk of corrosion failure due to coating dis-bondment, cathodic protection shielding, pitting corrosion, stray corrosion, stress corrosion cracking and AC interference. Those tasked with maintaining these pipelines and transmission electric structures require an in-depth understanding of the locations where these aging pipelines and transmission towers are at risk of localized corrosion attack and cracking. Many factors associated with these corrosion areas are corrosive soils, presence of dis-bonded coatings, CP shielding, AC interference, copper grounding, inadequate cathodic protection. These areas have a much higher statistical probability of catastrophic failure. Most of the time initiation of localized corrosion and pitting corrosion are detected by coincidence in excavation and digs and is not targeted or predicted by analysis of corrosion performance parameters. Visual inspection, Internal or In-line inspection (ILI) tools for pipe lines have limited capability for detecting or identifying localized corrosion initiation due to coating dis-bondment, cathodic protection shielding and AC interference.
A brief description of degradation mechanisms and corrosion assessment techniques for evaluation of aging structures, CP shielding, AC interference will be provided. Specific attention will be given to scientific and technical concepts for cathodic protection shielding, AC corrosion activity and assessing corrosion rate.
The case histories portion of the presentation will include projects that involved CP shielding by coatings,AC corrosion assessment, coating dis-bondment and cathodic protection investigations.
Dr. Zamanzadeh (Dr. Zee) is a NACE Certified Corrosion Specialist with over 30 years of practical experience in corrosion engineering, materials selection and design, protective coatings, and cathodic protection. He has worked in the oil and gas, electric power utility, and other industries throughout his career, and has resolved a wide range of materials and corrosion engineering concerns for these industries. Dr. Zee is the Technical Director and primary consultant on projects related to the gas and oil industry, and electric power utility industry in the following disciplines: 1. Setting Up Corrosion Risk Assessment/Corrosion Mitigation Programs for Large Energy Related Companies; 2. Corrosion Mitigation (Coatings, Cathodic Protection, Corrosion Inhibitors, Materials Selection); 3. Failure Analysis Root Cause Determination; 4. Big Data Analysis; 5. QA/QC Management; 6. Corrosion Engineering Courses (NACE Approved Instructor). His degrees include a B.S. and M.S. in Materials Science and Engineering and a Ph.D. in Materials Science. He joined NIOC as a corrosion engineer upon completion of his doctoral work in 1980. In 1985 he joined Carnegie Mellon University in the capacity of a Post-Doctoral Research Associate under a corrosion grant from IBM. He holds four certifications from NACE International that includes Coatings, Materials Selection and Design Specialist and Corrosion Specialist. Dr. Zamanzadeh is the recipient of the NACE Fellow Award (2008); ASM Fellow Award (2006); NACE Outstanding Service Award (1996), ASM Entrepreneur of the Year Award (2004), and the Colonel Cox Award for the Appalachian Underground Corrosion Short Course (2010).
