Abstract:
Copper and copper alloys are universal in petroleum handling and processing equipment, yet they remain vulnerable to corrosive attack by various hydrocarbon streams. This poster introduces an integrated suite of improved laboratory techniques for evaluating copper corrosion induced by liquid and gaseous petroleum products, as well as lubricating greases. Building on established ASTM standards—D130 (copper strip test for liquid fuels), D1838 (copper strip test for liquefied petroleum gases), and D4048 (copper corrosion detection from greases), we detail refined sample preparation, instrumentation, and procedural controls that enhance reproducibility and sensitivity. Key innovations include optimized copper‐coupon surface preparation to reduce variability, precise thermal conditioning of test baths for consistent temperature control, and updated protocols for accelerated gas‐phase exposure. Comparative case studies demonstrate how these methods detect early‐stage corrosivity in aviation gasolines, diesel fuels, LPG mixtures, and industrial greases, correlating visual coupon discoloration with quantifiable corrosion indices. The results underscore the importance of rigorous copper‐strip testing in predicting material compatibility and guiding the design of corrosion‐resistant components in storage tanks, pipelines, and refinery systems. In conclusion, these advancements provide laboratories and manufacturers with a robust framework to safeguard copper‐based infrastructure and extend equipment service life in petroleum environments.
