The Norwesco 2500 Gallon 30 Degree Cone Bottom Tank with Poly Stand (SKU N-40674) is built for full-drain batching and chemical service where the contents need to empty completely through the cone. Molded in blue High Density Linear Polyethylene with a 16" lid, a 2" outlet, and a 1.9 specific gravity rating, this closed-top cone tank sits on a matched poly stand and stands 116" tall on a 99" diameter footprint. It is FDA approved and rated to a maximum operating temperature of 120 F / 48 C. Empty it weighs 949 lb.
Will it handle your batch?
The 30-degree cone empties by gravity, so use the poly stand height to clear a valve, pump, or transfer container underneath. Sizing is about weight, not just gallons. Filled with water this Norwesco cone tank carries roughly 20,850 lb, and at its full 1.9 SG rating the maximum rated contents weight reaches about 39,615 lb. Confirm your stand pad and floor can carry that loaded weight before you fill. Run your exact fluid through the Tank Sizing Calculator and the Tank Sizing Guide to match gallons and SG to the tank rating.
Chemical compatibility
This tank is HDLPE with a 1.9 specific gravity rating — the top of the density line for this cone tank, which means every chemical in the list below sits at or under its limit and you are not buying up to a heavier shell to run strong acids. Compatibility is drawn from the Snyder Industries OEM chemical resistance chart and is concentration- and temperature-specific, so confirm your exact chemical, concentration, temperature, and fitting plus gasket materials first. At the 1.9 rating this tank supports higher-density chemicals including Sulfuric Acid (98%, CPVC fittings, Viton gaskets), Hydrochloric Acid (37%, PVC, Viton), Phosphoric Acid (85%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Sodium Hypochlorite (under 16.5%, PVC, Viton), Ferric Chloride (50%, PVC, EPDM), Ethylene Glycol (100%, PVC, EPDM), and Peracetic Acid (30%, 316SS, Aflas). Lighter service runs with margin to spare: DEF and 32.5% Urea Solution only need a 1.35 rating, and salts like Calcium Chloride (40%), Aluminum Sulfate (50%), and Sodium Carbonate (30%) need only 1.5. If your only service is DEF or dilute salts, call 866-418-1777 and ask whether a lighter-rated tank fits your budget. Every rating assumes near-ambient service — this tank's ceiling is 120 F / 48 C, and hot or exothermic service derates both the resin and the gaskets. See the full Chemical Compatibility Database for the concentration- and temperature-specific detail.
Match the fitting and gasket, not just the tank
The most common mistake on a cone tank in chemical service is bolting the wrong bulkhead or gasket onto that 2" outlet. The polyethylene shell can hold the chemical while an incompatible PVC-versus-316SS fitting or an EPDM-versus-Viton gasket fails at the drain. The 2" outlet and 16" lid are molded in, but wetted fittings, bulkheads, and gaskets (PVC, CPVC, 316SS, Viton, EPDM, Aflas per chemical) are sourced separately — peracetic acid needs 316SS with Aflas, the strong acids need Viton, and most salts and glycols run on PVC with EPDM. Match every wetted part to the chemical, reference the technical drawing on this page for outlet and lid placement, and call 866-418-1777 to spec fittings to your fluid.
