Aging storage tanks, increased environmental concern and government regulations have created the need for liquid transportation companies to implement stringent maintenance procedures to protect tank bottoms and prevent leakage before they occur. Linings are described as less costly and faster to install than new tank bottoms, and reportedly extend the life by 10 to 20 years. With a thickness of 60 to 65 mils, the linings can be considered secondary tank bottoms tightly bonded to the storage tank. FRP linings are designed to prevent internal corrosion and helps reduce potential for leakage from perforation of the tank bottom due to soil-side corrosion. According to API codes 650 and 653, protecting the tank bottom with a lining system is recommended when 50% or less of the tank bottom materials have corroded. If 75% of the material has corroded, the bottom must be replaced. The glass-reinforced linings reportedly provide sufficient strength to bridge small perforations in the supporting steel bottom caused by external corrosion. They also are not sensitive to internal pits and other surface irregularities, which may occur and interfere with lining installation.
