AMPP Paper 16225-2021: Cathodic Protection Coupon Interpretation in Multiple Pipeline Corridors

�� FREE PREVIEW (First 5 Pages) ✔ First 5 pages free to download · No email required · Full document available after purchase This paper examines the challenges of cathodic protection assessment in complex pipeline corridors, where multiple pipelines are bonded together. It addresses the interpretation of coupon measurements, particularly for new pipelines situated alongside existing infrastructure. The study highlights the importance of soil-access tubes or close-coupled reference electrodes for accurate potential readings and provides recommendations for reliable corrosion protection monitoring. Key topics include equalization currents, IR-drop, and the limitations of stationary reference electrodes. The first five pages are available for free preview.
