FRP LINING EXECUTING METHOD IN THE EXISTING STEEL STORAGE TANK

摘要

Provided is an FRP(Fiberglass Reinforced Plastic) lining execution method performed on an existing steel buried oil tank to enhance work efficiency involved with the maintenance of corrosion test and oil leakage. To execute the FRP lining, inflammable gas inside the buried tank(1) is first measured. Then, an oil feeing pipe(2) or a suction pipe(3) each connected to a valve(6,7) is cut to empty gasoline out of the tank(1) by using an air drive pump or a pressure resistance. The valves(6,7) are closed when the buried tank(1) is repaired or filled with water. Next, water and organic oil absorbent are provided into the tank(1) to absorb floating oil. An opening is formed to clean the inside of the tank(1). An FRP for delaying degradation of the tank(1) is adhered onto the inner circumferential surface of the tank(1), where the FRP is hardened by ultraviolet radiation.
