The Norwesco 3000 Gallon 15 Degree HDPE Cone Bottom Tank in Blue is a full-drain process vessel built for chemical service. Molded from high density linear polyethylene with a 1.9 specific gravity rating, it holds 3,000 gallons and stands 120 inches tall on a 91 x 91 inch footprint. The shallow 15-degree cone bottom drains slurries and settled solids toward the outlet without the steep cone height of 30- or 45-degree designs, which keeps overall height manageable while still clearing the tank between batches. If you are weighing cone angles, the Norwesco Cone Bottom Tank Buyer's Guide and the dedicated 3000 gallon 15 degree cone bottom tank guide walk through the tradeoffs.
Will it handle your application
This is a heavy vessel once filled. Plain water at full volume weighs about 25,020 lb, and at the tank's maximum rated 1.9 specific gravity the contents can reach 47,538 lb. That weight drives your stand, cone-support structure, and anchoring decisions, so size the steel and pad for the worst-case load, not the water number. A cone bottom tank like this always rides in an elevated stand or support structure because the sloped bottom needs clearance for the drain valve. The listing does not specify a factory fitting or outlet manifest, so confirm dimensions and outlet locations against the technical drawing on this page, and call 866-418-1777 to verify the fitting layout before you fabricate the stand or order elastomers. Use the Tank Sizing Calculator and Tank Sizing Guide to match capacity and weight to your space.
Chemical compatibility
This tank is HDLPE with a 1.9 specific gravity rating, which covers a broad range of dense process chemicals. The 1.9 SG figure is the maximum rated density for this vessel; if your chemical exceeds roughly 1.9 specific gravity, no higher-rated version of this size exists, so call to discuss alternatives. Always confirm your chemical, its concentration, and operating temperature against the OEM chemical-resistance chart before committing, since compatibility is concentration- and temperature-specific. Fitting and gasket materials matter as much as the tank wall. Common process fits include DEF at 32.5% (316SS fittings, EPDM gaskets) and 50% urea solution, along with a long list of acids, salts, and glycols. Chemicals confirmed compatible within this SG rating include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (under 16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). See the full Chemical Compatibility Database for concentration- and temperature-specific guidance.
The mistake to avoid
The costly error on a chemical cone bottom tank is matching the tank wall to your chemical but using the wrong fitting and gasket material. Several services on this list will not tolerate PVC fittings: DEF, peracetic acid, propylene glycol, and zinc orthophosphate all call for stainless 316SS rather than PVC or CPVC. Gaskets vary just as much. Sodium hypochlorite under 16.5% and the strong acids above need Viton, not the EPDM that works for the salts and glycols, and peracetic acid at 30% is the outlier that needs Aflas gaskets with 316SS fittings, not Viton or EPDM. Pair the fitting and gasket material listed for your specific chemical, and verify the resin against the OEM chart for your concentration and temperature.
