Can gasoline be stored in a tank without anti-corrosion treatment on its inner walls?

Can gasoline be poured into a tank that has been built without anti-corrosion treatment on its inner walls? Will it contaminate gasoline?
Temporarily store or keep for the long term? It doesn’t matter whether it’s gasoline in its finished form or as a semi-finished product; the level of corrosivity is also important. If it’s an intermediate product, its corrosivity is usually high, so it’s not suitable for use. Finished gasoline has lower corrosivity, but long-term storage will still have an impact on the quality of the gasoline, and there’s no need to save such a small amount of money. You can simply use epoxy paint that is resistant to heat, oil, and static electricity. It’s best to apply two base coats, two intermediate coats, and three top coats, with a thickness of 350 um; it won’t cost much.
Are you sure anti-corrosion won’t cost much? Sandblasting for rust removal to Sa2.5 standard – following your specification of two bottoms, two middles, and three sides, the cost should be at least 150 yuan per square meter. The cost of anti-corrosion treatment for a tank with a volume of 3,000 cubic meters is quite high ； Generally, corrosion protection in design covers the top of the tank and the 2 meters below it, as well as the bottom of the tank and the 2 meters above it, right? Epoxy zinc-rich primer and antistatic coating – are two coats on both sides sufficient? Please point out any mistakes
From the perspective of using floating pads! It’s best to do anti-corrosion treatment! Without anti-corrosion measures, it has a significant impact on the service life of the floating disk sealing tape! Especially the floating disk that uses a sac-type sealing design!
It can be stored, but over time the storage tank will develop a lot of rust, and the filter is prone to clogging, which has an impact on the quality of the goods.
Absolutely, we’ve been doing this for over 10 years with no problems; however, the lower two layers of panels still require internal anti-corrosion treatment. There’s really no need for full anti-corrosion treatment
For the floating-roof finished oil tanks that store gasoline at 40°C, non-carbon-based phenolic epoxy antistatic paint is used on the upper surface of the tank bottom, the inner walls of the pipes, and the lower surface of the tank roof; the thickness of this paint layer is 200–300 μm. Epoxy coal tar anti-corrosion paint is used on the lower surface of the tank bottom, with a total thickness of 300 μm resulting from these two coats of paint. Due to the requirements for heat reflection and gloss on the outer wall of the tank, an epoxy zinc-rich primer is used as the base coat, an epoxy ferrochrome intermediate coat is used as the middle coat, and an aliphatic polyurethane top coat is used as the final coat, giving a total thickness of 280 μm.
I’ve seen ones that have been in use for 10 years without any anti-corrosion treatment, with the bottom of the tank and the underlying plates corroded and flaking off, by an estimated 2 millimeters or more. I’ve also seen those with anti-corrosion treatment, which are basically in as good condition as new. If you want money, don’t take a life. The service life is absolutely different! It all depends on your idea! !
