Corrosion engineers have for many years relied upon test results from laboratory studies to select materials of construction for the chemical process industries. While the chemistry of the operating plant environment can sometimes be duplicated in the laboratory, factors of velocity, hot and cold wall effects, existence of crevices, chemical reaction of the fluid during the test, stress levels of the equipment, contamination with products of corrosion, trace impurities, dissolved gases, etc. also have an influence on the quality of the answer. Then too, the progress of the corrosion reaction itself varies with time. Notwithstanding, immersion testing remains the most widely used method for making materials of construction selections.
