The 10000 Gallon 15 Degree Cone Bottom Tank in Black is a Norwesco polyethylene cone bottom tank rated to a 1.5 specific gravity, built for full-discharge handling of heavier-than-water solutions. It measures 141 inches in diameter and stands 180 inches tall, and the 15-degree cone drains toward the center outlet so liquids and settling solids clear the floor instead of pooling. This is the size operators search for when they need a serious cone bottom tank for batching, blending, and gravity-fed dosing.
Will it work for your application
The 1.5 specific gravity rating is the number that decides this. At full water level the contents weigh 83,400 lb; the tank is rated to carry up to 125,100 lb of liquid, which is what lets it hold a fluid up to 1.5 times the density of water. Confirm the SG of your solution at its actual storage temperature before you commit, because the cone-bottom geometry concentrates the full liquid load on the support stand and the lower wall. The 141-inch footprint sets the diameter of the matching cone stand you will need; size the pad and the stand to the rated content weight, not just the water weight. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm dimensions and clearances against your space, and see the technical drawing on this page for outlet placement and the cone angle. If you are weighing this against a steeper cone or a different gallonage, the Norwesco Cone Bottom Tank Buyer's Guide walks through 15 vs 30 vs 45 degree selection.
Chemical compatibility
This tank is polyethylene rated to a 1.5 specific gravity. The resin designation is not confirmed in our data, so confirm the exact resin (HDLPE vs XLPE) with the manufacturer before any chemical service, as that distinction changes long-term resistance. Within the 1.5 SG limit, this tank is suitable for these chemicals at the concentrations and fitting/gasket pairings shown, per the OEM chemical-resistance chart (always concentration- and temperature-specific): Acetic Acid at 60% with PP/PVC fittings and EPDM gaskets; Aluminum Sulfate at 50% (PVC/EPDM); Calcium Chloride at 40% (PVC/EPDM); DEF at 32.5% (316SS/EPDM); Ferrous Sulfate at 20% (PVC/EPDM); Magnesium Chloride at 30% (PVC/EPDM); Sodium Carbonate at 30% (PVC/EPDM); Urea Solution at 50% (PP/PVC, EPDM); and Ozonated Water up to 10 PPM (PVC/EPDM) — verify this last one in the full database, as it has no dedicated page yet. Match the fitting and gasket material to the chemical, not just the tank: note that DEF requires 316 stainless fittings rather than PVC, and Acetic Acid and Urea Solution accept PP or PVC, so don't default every port to PVC.
Chemicals that need a higher-SG tank
Several common process chemicals exceed the 1.5 SG rating of this tank and require a 1.9 SG build instead, so do not store them here: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid (Viton), Hydrofluoric Acid (Viton), Hydrofluosilicic Acid (Viton), Hydrogen Peroxide (Viton), Peracetic Acid (316SS/Aflas), Phosphoric Acid (Viton), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite (Viton), Sodium Thiosulfate, Sulfuric Acid (CPVC/Viton), and Zinc Orthophosphate. The strongest oxidizers and acids on this list also escalate the seal material, moving from EPDM to Viton (hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, sodium hypochlorite, sulfuric) or Aflas (peracetic acid), with CPVC or 316 stainless fittings, so the upgrade is both tank rating and seal material. If your chemical is on this list, you need the 1.9 SG version of this tank — call us at 866-418-1777 to source the matching 1.9-rated cone bottom build. Verify your exact chemical, concentration, and temperature in the full Chemical Compatibility Database before ordering.
Freight and ordering
This tank ships LTL freight, quoted live to your ZIP. We route it from whichever of the two Norwesco plants is closer to you — Fairfield, TX or St. Bonifacius, MN — so the quote isn't arbitrary. On an 83,400 lb water-weight, 141-inch-diameter unit, freight is the single largest line item after the tank itself, and the TX-versus-MN split materially changes the number, so get a real quote before you budget. Use the Freight Cost Estimator for an instant number to your ZIP, or call 866-418-1777 and we will route your shipment from the closer plant. List price is shown before freight, which is quoted separately.
