The Enduraplas 10000 Gallon Black Cone Bottom Tank is a full-drain bulk vessel built for high-specific-gravity chemical service, rated to a specific gravity of 1.9. Molded in black polyethylene, this cone bottom tank stands 193 inches tall on a 144 x 144 inch (12 ft x 12 ft) footprint and requires a matching cone-bottom support stand, because a cone tank carries its entire load on the stand rather than on a flat pad. If you are spec'ing one of these, work through the three questions below before you commit.
Will it hold what I'm storing?
On a cone tank this size the 1.9 specific-gravity rating is the number that matters most. At 10,000 gallons, plain water alone weighs 83,400 pounds full, while the tank is rated to carry up to 158,460 pounds of contents at its full SG rating, roughly 75,000 pounds more than water. That entire load transfers into the stand legs and the slab beneath them, so the support structure and a foundation sized for the 144 x 144 inch (12 ft x 12 ft) base must be engineered for the loaded figure, not the empty tank. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your fill volume and working weight, then pair the tank with a correctly rated stand using the Cone Bottom Tank Stand Compatibility Matrix. For a deeper walkthrough of geometry, drainage, and stand selection at this size, see the 10000 Gallon 30 Degree Cone Bottom Tank buyer's guide.
Chemical compatibility
This tank is molded from polyethylene rated at a 1.9 specific gravity. The resin is recorded as HDLPE in our data but carries an open flag, so confirm whether your tank is HDLPE or XLPE with us before placing it into chemical service. Compatibility below is concentration- and temperature-specific per the OEM chemical-resistance chart; verify your operating temperature and exact concentration for your application. Fitting and gasket materials listed are the recommended pairings for each chemical:
- Acetic Acid 60% — PP/PVC fittings, EPDM gasket
- Aluminum Sulfate 50% — PVC fittings, EPDM gasket
- Calcium Chloride 40% — PVC fittings, EPDM gasket
- DEF 32.5% — 316SS fittings, EPDM gasket
- Ethylene Glycol 100% — PVC fittings, EPDM gasket
- Ferric Chloride 50% — PVC fittings, EPDM gasket
- Ferric Sulfate 60% — PVC fittings, EPDM gasket
- Ferrous Sulfate 20% — PVC fittings, EPDM gasket
- Hydrochloric Acid 37% — PVC fittings, Viton gasket
- Hydrofluoric Acid 48% — PP/PVC fittings, Viton gasket
- Hydrofluosilicic Acid 26% — PP/PVC fittings, Viton gasket
- Hydrogen Peroxide 50% — PVC fittings, Viton gasket
- Magnesium Chloride 30% — PVC fittings, EPDM gasket
- Peracetic Acid 30% — 316SS fittings, Aflas gasket
- Phosphoric Acid 85% — PVC fittings, Viton gasket
- Polyaluminum Chloride — PVC fittings, EPDM gasket
- Potassium Carbonate 50% — PVC fittings, EPDM gasket
- Potassium Hydroxide saturated — PVC fittings, EPDM gasket
- Propylene Glycol — PP/316SS fittings, EPDM gasket
- Sodium Bisulfate — PVC/PP fittings, EPDM gasket
- Sodium Bisulfite — PVC/PP fittings, EPDM gasket
- Sodium Carbonate 30% — PVC fittings, EPDM gasket
- Sodium Hypochlorite under 16.5% — PVC fittings, Viton gasket
- Sodium Thiosulfate 40% — PVC fittings, EPDM gasket
- Sulfuric Acid 98% — CPVC fittings, Viton gasket
- Urea Solution 50% — PP/PVC fittings, EPDM gasket
- Zinc Orthophosphate — PP/316SS fittings, EPDM gasket
- Ozonated Water up to 10 PPM — PVC fittings, EPDM gasket

The mistake to avoid
The two errors that cost the most on a tank like this are matching the wrong gasket to the chemical and reading SG carelessly. The pack pattern is consistent: EPDM works for salts and glycols such as calcium chloride, ethylene glycol, and sodium carbonate; Viton is called for on oxidizers and strong acids such as sulfuric 98%, sodium hypochlorite, hydrogen peroxide, and phosphoric; and Aflas is specified for peracetic acid 30%. Putting EPDM on sulfuric, sodium hypochlorite, or peracetic service is a leak waiting to happen, so self-select your fittings from the list above before you order. On the dosing side, instrument the tank correctly for your medium and operating depth; the level gauge selection guide walks through radar, ultrasonic, hydrostatic, and magnetostrictive options for chemical tanks. Before the tank goes into operation, get your labeling right with the tank labeling and signage compliance guide. You can confirm dimensions and the cone profile on the technical drawing on this page.
