The glass steel acid tank is a kind of non metal composite body composed of resin and glass fiber winding machine by microcomputer control and the service life of mechanical winding FRP tanks normal for 8 to 15 years, and the length of the service life of the products quality, installation base, storage material and chemical properties, content, standard the operation has a very important relationship. The maximum guarantee of the glass fiber reinforced plastic acid and alkali tank inside and outside is always maintained at atmospheric pressure. Glass fiber reinforced plastic storage tank is usually used as a whole winding, the intensity of the positive pressure is relatively strong, but the ability to resist the negative pressure is weak, especially the diameter of more than 2000mm of storage tanks. There are more than half of the common quality accidents in the tank, because the exhaust hole is closed or the exhaust hole is blocked, so that the internal pressure of the storage tank is negative. Therefore, to keep the vent hole is always open or inside the tank has been maintained at atmospheric pressure, the safety of the tank is very critical. Because of the actual needs, in the case of no increase in fixed investment, with the same storage tank frequently different media, this is very undesirable. Anti corrosion performance of glass steel acid tank, mainly rely on the inner tank for corrosion, acid and alkali, salt of different medium and different temperature using the corrosion resistant resin layer is different, a storage tank for acid alkali, anti corrosion layer will soon breakdown corrosion lining. Similarly, even the acid storage tank, often loaded with different media acid, the corrosion of the inner tank is quite large, thus affecting the life of the tank. Glass steel acid-base storage tank in use after a period of time, if frequent moves, will cause the glass steel tank structure layer axial stress damage, so that the glass steel tank acid-base strength decreased, which will shorten the service life of FRP tanks. The influence of the service life of FRP tank acid-base factors influencing factors of service life of FRP acid-base storage tank the
