The Enduraplas 3200 Gallon Black Cone Bottom Tank is a full-drain bulk vessel built for chemical service, rated to 1.9 specific gravity so it can hold dense process liquids that would overstress a standard 1.5 SG tank. It stands 116 inches tall on a 110 x 110 inch footprint, holds 3,200 gallons, and is molded from black polyethylene that blocks UV and suppresses algae growth in stored solutions. The cone bottom drains to a single low point, which is what you want for slurries, settling chemicals, and any product you need to evacuate completely between batches.
Will it work for your application?
The black polyethylene construction and the 1.9 SG rating are the headline numbers here. Filled with water at 1.0 SG, the tank carries roughly 26,688 pounds; at its maximum rated content density the load reaches 50,707 pounds. Use those two figures to size your cone-bottom stand and foundation — the stand must be rated for the heavier loaded weight at your actual product density, not for water. The 110 x 110 inch footprint is the stand's working dimension. One more number to plan around: at 116 inches the tank is nearly 9'8" tall before it sits on any stand, so confirm overhead clearance at the install site and plan a craned or forklift offload, since this exceeds standard dock-door height. For help matching the right structural stand, see our cone bottom tank stand compatibility matrix, and run the numbers with the Tank Sizing Calculator and Tank Sizing Guide. Refer to the technical drawing on this page for the cone angle, fitting locations, and overall dimensions before you finalize your piping layout.
Chemical compatibility
This polyethylene tank is rated to 1.9 specific gravity. The pack lists the resin as HDLPE pending OEM confirmation, so confirm HDLPE versus XLPE with us before committing to chemical service — cross-link versus linear materially changes resistance to the oxidizers below. Always match fitting and gasket materials to your specific chemical, concentration, and temperature, and verify against the OEM concentration- and temperature-specific chemical-resistance chart.
Chemicals this tank's resin and 1.9 SG rating can handle, with the recommended fitting and gasket materials, include:
- Acetic Acid at 60% — PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% — PVC fittings, EPDM gaskets
- Calcium Chloride at 40% — PVC fittings, EPDM gaskets
- DEF at 32.5% — 316SS fittings, EPDM gaskets
- Ethylene Glycol at 100% — PVC fittings, EPDM gaskets
- Ferric Chloride at 50% — PVC fittings, EPDM gaskets
- Ferric Sulfate at 60% — PVC fittings, EPDM gaskets
- Ferrous Sulfate at 20% — PVC fittings, EPDM gaskets
- Hydrochloric Acid at 37% — PVC fittings, Viton gaskets
- Hydrofluoric Acid at 48% — PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid at 26% — PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide at 50% — PVC fittings, Viton gaskets
- Magnesium Chloride at 30% — PVC fittings, EPDM gaskets
- Peracetic Acid at 30% — 316SS fittings, Aflas gaskets
- Phosphoric Acid at 85% — PVC fittings, Viton gaskets
- Polyaluminum Chloride — PVC fittings, EPDM gaskets
- Potassium Carbonate at 50% — PVC fittings, EPDM gaskets
- Potassium Hydroxide at saturated concentration — 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 Carbonate at 30% — PVC fittings, EPDM gaskets
- Sodium Hypochlorite at under 16.5% — PVC fittings, Viton gaskets
- Sodium Thiosulfate at 40% — PVC fittings, EPDM gaskets
- Sulfuric Acid at 98% — CPVC fittings, Viton gaskets
- Urea Solution at 50% — PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate — PP/316SS fittings, EPDM gaskets
- Ozonated Water up to 10 PPM — PVC fittings, EPDM gaskets
Note the gasket split: oxidizers like sodium hypochlorite, hydrogen peroxide, sulfuric acid, and the fluoride acids call for Viton, while salts and glycols run fine on EPDM. Full concentration- and temperature-specific data lives in our Chemical Compatibility Database.
The mistake to avoid
The most common error on a tank this size is under-rating the stand and the SG. This vessel is rated to 1.9 SG and can carry over 50,000 pounds of dense product — far past the roughly 26,700 pounds of plain water. If you build a stand or pour a pad sized for water weight, you are building for less than half the real load. Confirm your product's specific gravity, multiply it against the water-fill weight, and size the structure for that number. For pickup and drain plumbing on the cone, plan the top-fitting layout deliberately — see our guides on tank top fitting placement strategy, level gauge selection for chemical service, and hazard labeling and signage compliance.
