CLAD STEEL TANKS WHIP CHEMICAL CORROSION THREAT A critical corrosion problem faced this chemical producer. In a plant that can process up to 100 million pounds of fats and oils annually, unsatu rated acids and moisture would cause fatty acids to attack iron during storage. Presence of iron salts would threaten instability and as little as 30 to 40 parts of iron per million are enough to darken fatty acids. With lighter colors getting a premium price and output headed for high-grade consumer products, product quality had to be protected. T h e answer: economical clad steel equipment ended the danger of corrosion during storage, virtually elimi nated iron pick-up. Cooperative planning between the designers and equipment builder solved this problem. Stainlessclad steel was specified for four horizontal feed tanks, two settling tanks and two insulated cone roof storage tanks. Here a light layer of cladding provides the smooth, corrosion-resistant surface of more ex pensive solid alloy, while the low-cost carbon steel backing gives strength and rigidity. Integral and per manent bonding of cladding and backing prevents seepage of acid to the backing. Smooth contours and joints possible with clad permit easy cleaning and lessen the chances of contamination. If you are looking for economical product pro tection, follow the profitable lead of this chemical producer. Call in your equipment builder early in your planning of new equipment. Working with your engineers and consultants, he can contribute his skill, know-how, and understanding of your field t o give you the low-cost, long-lived clad steel equipment your process demands.
