The Norwesco 10000 Gallon 30 Degree Cone Bottom Tank is a full-drain HDPE process tank built for chemical service, molded from high density linear polyethylene in blue and rated to a 1.9 specific gravity. The 30-degree cone bottom forces complete gravity discharge of slurries, settling solids, and viscous chemistries that would otherwise pool in a flat-bottom tank. At 10,000 gallons it stands 190 inches tall on a 141 x 141 inch footprint, so plan your stand, building clearance, and discharge plumbing around that height before you order this cone tank.
Will it work for your application
This is a heavy industrial cone bottom tank, and loaded weight drives every decision around it. Filled with water it carries roughly 83,400 lb, and at its maximum 1.9 SG rating the contents alone reach about 158,460 lb. A cone-bottom tank holds none of that load on the ground - it transfers everything into the support stand and the slab beneath it, so the stand, ring, and foundation must be engineered for the full rated weight of whatever you store, not just water. That 1.9 SG rating is the heaviest-duty cone option Norwesco molds at this size, so no heavier-rated alternative is needed even for dense chemistries like 98% sulfuric acid or 85% phosphoric acid. Confirm the geometry against the technical drawing on this page when you spec your stand and outlet. Note that fitting and outlet configuration is not fixed in this listing - confirm bulkhead, outlet, and manway specs by phone (866-418-1777) before ordering, since the recommended fitting material varies by chemical. If you are weighing this against the 15 and 45 degree versions, our Norwesco cone bottom tank buyer's guide walks through cone-angle selection, and the dedicated 10000 gallon 30 degree cone bottom tank guide covers this exact size. Run your fill volume through the Tank Sizing Calculator and review the Tank Sizing Guide if you are still narrowing capacity.
Chemical compatibility
This tank is HDLPE resin rated to a 1.9 specific gravity, which is what lets it carry dense chemistries at full volume. Compatibility below is drawn from the OEM chemical-resistance chart, which is concentration and temperature specific - match your exact concentration and operating temperature to the chart, and verify fitting and gasket materials before you put any chemical into service. As a quick rule of thumb, EPDM gaskets cover the salts, glycols, and most bases; Viton is required for the oxidizing and aggressive acids; and two outliers need special materials - peracetic acid takes Aflas gaskets, and both DEF and peracetic acid call for 316SS fittings. Confirmed-compatible chemistries and their recommended fitting and gasket materials include acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50% (PVC/EPDM), calcium chloride at 40% (PVC/EPDM), DEF at 32.5% (316SS fittings, EPDM), ethylene glycol at 100% (PVC/EPDM), ferric chloride at 50%, ferric sulfate at 60%, and ferrous sulfate at 20% (all PVC/EPDM). Aggressive acids call for Viton gaskets: hydrochloric acid at 37% (PVC/Viton), hydrofluoric acid at 48% and hydrofluosilicic acid at 26% (both PP/PVC, Viton), hydrogen peroxide at 50% (PVC/Viton), phosphoric acid at 85% (PVC/Viton), sodium hypochlorite below 16.5% (PVC/Viton), and sulfuric acid at 98%, which requires CPVC fittings with Viton gaskets. Also confirmed are magnesium chloride at 30%, peracetic acid at 30% (316SS fittings, Aflas gaskets), polyaluminum chloride, potassium carbonate at 50%, potassium hydroxide (saturated), propylene glycol (PP/316SS, EPDM), sodium bisulfate and sodium bisulfite (PVC/PP, EPDM), sodium carbonate at 30%, sodium thiosulfate at 40%, urea solution at 50%, zinc orthophosphate, and ozonated water up to 10 PPM (PVC/EPDM).

The mistake to avoid
The most expensive error on a tank this size is matching the cone-bottom support to water weight instead of chemical weight. A stand rated for 83,400 lb of water will be overloaded the moment you fill it with a 1.9 SG chemistry approaching 158,460 lb - the full cone load rides on the structure, not the floor. Spec the stand and foundation to your chemical's actual weight, and use our cone bottom tank stand compatibility matrix to pick a stand engineered for that load. Then pair every fitting and gasket to the specific concentration in the resistance chart rather than reusing whatever was on a previous tank.
