The Norwesco 6000 Gallon 15 Degree Cone Bottom Tank handles aggressive process chemistry at full scale. Molded in blue High Density Linear Polyethylene (HDLPE) with a 1.9 specific gravity rating, this 6000-gallon cone bottom tank stands 195 inches tall on a 102 by 102 inch footprint. The 15-degree cone bottom drains by gravity, so settled solids and product clear toward the outlet instead of stalling on a flat floor. This is a tank-only listing sized for a matched steel or poly stand rated for the full load.
Will it hold what you are running?
The 1.9 SG rating is the number that matters here. Full of water this tank carries roughly 50,040 pounds; loaded to its maximum rated contents it is engineered for about 95,076 pounds, which is what lets it handle dense chemicals up to a 1.9 specific gravity. At 1.9 SG this is the highest-rated wall offered in this size and cone, so a chemical heavier than 1.9 SG is not supported in this tank. Confirm your fluid's specific gravity against that 1.9 ceiling before you commit; if your product runs heavier, call 866-418-1777 to discuss alternatives. Overfilling a cone bottom on an undersized stand is the most common and most expensive mistake at this volume. Use the Tank Sizing Calculator and the Tank Sizing Guide to size the tank and its support to your actual fill weight, and see the technical drawing on this page for the cone geometry and port layout.
Chemical compatibility
This tank is molded in HDLPE with a 1.9 SG rating, which covers a broad slate of industrial chemistry. Always match your fittings and gaskets to the chemical, not just the tank. The chemicals below are listed as compatible in our Chemical Compatibility Database, which is specific to concentration and temperature, so verify your service conditions before ordering. They fall into a few clear hardware groups. Oxidizing and strong-acid services run on Viton gaskets: Sodium Hypochlorite (under 16.5%, PVC), Hydrogen Peroxide (50%, PVC), Hydrofluoric Acid (48%, PP/PVC), Hydrofluosilicic Acid (26%, PP/PVC), Phosphoric Acid (85%, PVC), Hydrochloric Acid (37%, PVC), and Sulfuric Acid (98%, CPVC). Sulfuric acid at 98% sits near the upper edge of the 1.9 SG rating, so confirm your delivered concentration and temperature against the database before specifying. Services that call for 316SS fittings include DEF (32.5%, EPDM), Peracetic Acid (30%, Aflas gasket, the only Aflas line here), Propylene Glycol (PP/316SS, EPDM), and Zinc Orthophosphate (PP/316SS, EPDM). The remaining salts, carbonates, and glycols run on PVC fittings with EPDM gaskets: Acetic Acid (60%, PP/PVC), Aluminum Sulfate (50%), Calcium Chloride (40%), Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Polyaluminum Chloride, Potassium Carbonate (50%), Potassium Hydroxide (saturated), Sodium Bisulfate (PVC/PP), Sodium Bisulfite (PVC/PP), Sodium Carbonate (30%), Sodium Thiosulfate (40%), Urea Solution (50%, PP/PVC), and Ozonated Water (up to 10 PPM). Polyaluminum Chloride, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, and Zinc Orthophosphate have no concentration specified, so confirm your working concentration against the database, as compatibility can shift with strength. Cross-check every line against the full Chemical Compatibility Database before you finalize a fitting and gasket package.
Selecting the right cone and stand
At 6000 gallons the cone angle and stand pairing drive your install footprint and drain behavior. The 15-degree cone is the shallower, lower-profile option versus 30- and 45-degree cones. Two guides cover the trade-offs in detail: the Norwesco Cone Bottom Tank Buyer's Guide walks through 15 vs 30 vs 45 degree selection, and the 6000 Gallon 15 Degree Cone Bottom Tank guide goes deep on this exact size. For matching a support structure, the Cone Bottom Tank Stand Compatibility Matrix lays out which stands carry which tanks.
