500 Gallon 30 Degree Cone Bottom Tank with Poly Stand

The Norwesco 500 Gallon 30 Degree Cone Bottom Tank with Poly Stand (SKU N-40289) is built for controlled, full-drain dispensing of liquids and process chemicals.Molded in white polyethylene with a 1.5 specific gravity rating, it stands 87" tall on a 49" diameter footprint, carries a 2" outlet at the base of the 30-degree cone and a 16" lid up top, and weighs 209 lbs empty.The steep cone and matched poly stand let the tank empty completely under gravity, which is why this configuration shows up in searches for a 500 gallon Norwesco cone bottom tank with stand.

Will it work for your liquid?

Size to weight, not just volume.Full of water this tank holds about 4,170 lbs; at its maximum 1.5 specific gravity rating it can carry roughly 6,255 lbs of contents.Confirm your stand pad and floor can take the loaded weight on the 49" diameter footprint before you fill it.The tank is FDA approved, rated to 120 F / 48 C, and includes a 2" bottom outlet and a 16" fill lid; the technical drawing on this page shows the full dimensional layout.Run your numbers through the Tank Sizing Calculator and Tank Sizing Guide, and see the complete buyer's guide for this exact tank.Need a different volume?Compare the 300, 310, and 175 gallon versions.

Chemical compatibility

This tank is molded polyethylene with a 1.5 specific gravity rating.The resin is likely HDLPE, but confirm HDLPE vs XLPE with us before any chemical service, because that distinction changes compatibility for several of the acids below.Per the Snyder Industries OEM chemical resistance chart (which is concentration and temperature specific), this 1.5 SG tank suits chemicals such as acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ferrous sulfate (20%), magnesium chloride (30%), sodium carbonate (30%), urea solution (50%), and ozonated water (up to 10 PPM).DEF and urea only require a 1.5 SG rating, so this 1.5 SG tank comfortably exceeds what those services demand — useful headroom for DEF-storage buyers, where the chart calls for 316SS fittings on DEF.Most of the others call for PVC or PP fittings with EPDM gaskets.Always verify exact concentration, temperature, fitting and gasket against the Chemical Compatibility Database.

The mistake to avoid

Don't put a heavier chemical in a 1.5 SG tank.Fluids like ethylene glycol, ferric chloride (50%), hydrochloric acid (37%), hydrogen peroxide (50%), phosphoric acid (85%), sodium hypochlorite, and sulfuric acid (98%) all require a higher 1.9 SG rated tank — ask us for that heavy-duty 1.9 SG version rather than overloading this one.Watch the gasket and fitting class too: chlorinated and peroxide services need Viton gaskets rather than EPDM, 98% sulfuric acid specifically requires CPVC fittings (not PVC) with Viton, and peracetic acid (30%) needs 316SS fittings with an Aflas gasket.Matching the wrong plumbing to an aggressive chemical is a failure waiting to happen.
