Lining stainless steel vats with fiberglass to prevent attack by H2SO4
September 3, 2009
I hope you can help! my problem is with 1000 l containers made from 304 st/steel that carry sulfuric acid, when they are empty we still have a resedue of about 15 L of sulfuric at 97% left in the container. The containers are left sometimes with lids open; this then dilutes the acid making it very corrosive with the st/steel.
what I would like to know is that if I line the container with fiberglass will this be resistant against sulfuric acid less than
97%

John,
Fibreglass on its own will do little for you. What is important is the resin.
Personally I would use polypropylene lining. This should be adequate if the process is not heated.
