If a storage tank bottom is corroding quickly, it must either be replaced, or a thick-filmed, fiberglass reinforced plastic (FRP) lining must be applied to the existing tank bottom. Replacing a tank bottom can be a costly and time-consuming process. Proper selection and application of an FRP lining system with a 60 to 65-mil thickness can save time, money and prevent internal corrosion of the steel tank bottom for 10 to 20 years. Average corrosion rate of carbon steel storage tanks in crude oil service at ambient temperatures is more than 1 mil per year. Corrosion occurs even more quickly when a layer of water containing corrosive compounds such as salt and sediment settles to the bottom of a crude oil tank. Installing a thick fiber glass-reinforced lining system involves applying a primer, putty, catalyzed resin with a glass mat and a sealcoat. After the tank has been pumped dry and the surface properly prepared, the entire process takes substantially less than the downtime and costs associated with replacing the entire tank bottom. The paper describes the application of a FRP lining system, testing and metal repairs, and the use of catalyzed resin and glass mats.
