Abstract
In the synergy produced by the action of the percentages of sulfur, sodium, and other elements that comprise chemically Venezuelan petroleum coke in the company of a significant proportion of water in the mixture, generates an environment with corrosive indices important to any metal equipment to have interaction with it, both in the oil industry as in any other that use this fuel as a product or input into their operations. In this work, laboratory tests were conducted to determine the corrosion rate in a system consisting of metal par ASTM-A36 structural steel and stainless steel AISI / SAE 304, commonly found in business management and production of petroleum coke. The study was performed by gravity, which is the common methodology to establish mass loss values in the time using the corresponding international standards and thus be able to determine by experimental simulation, the lifetime of any structure exposed storage corrosion generated by means of this study, taking care preparation for anterior and posterior with the examination of the specimens or “corrosion coupons”. For this purpose joined a corrosion test, which produced a series of rectangular specimens previously appointed steels, which were superposed one on another, and subjects using electric resistance welding with non-consumable electrode, guaranteeing so had no material contribution to the double metal welding by another guy that could affect the study in the base metal of the board in question. Were compared to corrosion rates of each of the metals individually and studied together, revealing that it increases when the two (02) steels are interacting together.
