The Norwesco 10000 Gallon 30 Degree Cone Bottom Tank (SKU N-44103) is built for full-drain chemical service where you cannot leave product sitting in the bottom. This is a 10,000-gallon polyethylene cone bottom tank rated to 1.5 specific gravity, with a 30-degree cone floor that keeps solids moving toward the outlet so dosing chemicals, coagulants, and slurries empty cleanly instead of stratifying. Plan for it: 190 in tall, 141 x 141 in footprint, and it requires a load-rated support stand - a cone-bottom tank this size does not free-stand on the cone.
Will it work for your chemical?
The capacity decision comes down to weight, not just volume. Filled with water this tank carries 83,400 lb; at its maximum rated contents weight it carries 125,100 lb. Size the support structure and pad to the 125,100 lb max rated load - not the 83,400 lb water figure - and hand that number to your structural or stand vendor up front. Use the Tank Sizing Calculator to confirm your fill weight against the 1.5 SG rating before you commit, and the Tank Sizing Guide if you are sizing a new installation. The 1.5 specific gravity rating is the gating number: it tells you how dense a fluid the wall thickness will support, and it is the most common spec people misread on a cone bottom tank of this scale. You can verify dimensions and the cone geometry against the technical drawing on this page.
Chemical compatibility
This tank is polyethylene rated to 1.5 specific gravity. The resin grade reads as HDLPE on our data but is not fully confirmed - before placing any chemical into service, confirm HDLPE versus XLPE construction for your application, as cross-linked and linear polyethylene differ in chemical and stress-crack resistance. At the 1.5 SG rating, the following chemicals are compatible at the listed concentrations, with the fitting and gasket materials that should be specified for each:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets (no dedicated page yet - call us for this service)
These pairings are concentration- and temperature-specific - verify your exact concentration and operating temperature before ordering, and see our full Chemical Compatibility Database for the complete picture. DEF tank buyers should note this also reads as a clean fit for that service at 32.5%.
Chemicals that need a higher-SG tank
Several common chemicals are too dense for the 1.5 SG rating on this tank and require a 1.9 specific gravity tank instead. Do not put any of these in this 1.5 SG tank - call us at 866-418-1777 and we will spec the correct higher-SG cone bottom tank. Note the gasket material changes from EPDM for the acids and bleach below:
- Ethylene Glycol - PVC fittings, EPDM gaskets
- Ferric Chloride - PVC fittings, EPDM gaskets
- Ferric Sulfate - PVC fittings, EPDM gaskets
- Hydrochloric Acid - PVC fittings, Viton gaskets
- Hydrofluoric Acid - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide - PVC fittings, Viton gaskets
- Peracetic Acid - 316SS fittings, Aflas gaskets
- Phosphoric Acid - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate - PVC fittings, EPDM gaskets
- Potassium Hydroxide - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Hypochlorite - PVC fittings, Viton gaskets
- Sodium Thiosulfate - PVC fittings, EPDM gaskets
- Sulfuric Acid - CPVC fittings, Viton gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
You can confirm any of these 1.9-SG requirements yourself in our Chemical Compatibility Database before you order.
Freight
This tank ships LTL freight, quoted live to your ZIP code. Norwesco builds this tank in Fairfield, TX and St. Bonifacius, MN - we ship from whichever plant is nearest you to keep transit and cost down. At 190 inches tall this is an oversized load, so get a real number before you plan the install: run your ZIP through the Freight Cost Estimator or call 866-418-1777. For more on selecting between cone angles, see our Norwesco cone bottom tank buyer's guide and the 10000 gallon 30 degree cone bottom tank buyer's guide.
