Abstract


The current study investigates experimentally through gravimetric analysis the onsite corrosion rates of carbon steel, stainless steel and aluminum as materials of fabrication. The rectangular strips made of these materials are exposed to the actual process conditions extended over a period of 54 continuous months. Corrosion rates measured incrementally after each six months with new samples each time indicate that stainless steel is the less corroded material with maximum corrosion rate of 0.024 mpy as compared to carbon steel and aluminum with maximum corrosion rates of 1.0 and 0.27 mpy, respectively.
