The Enduraplas 10000 Gallon White Cone Bottom Tank is a 10,000-gallon, 1.9 specific-gravity cone bottom tank built in Converse, Texas for chemical service that needs full drainage and a high density margin. It stands 193 inches tall on a 144 x 144-inch footprint, molded from natural white polyethylene so you can eyeball the liquid level without opening the tank. The cone bottom empties to its low point on its own - no settling, no manual cleanout between batches - which is why operators running aluminum sulfate, ferric chloride, or sodium hypochlorite reach for this geometry instead of a flat-bottom vertical.
Will this tank handle my job?
The headline number on a chem tank is specific gravity, and this one is rated to 1.9 - meaning the polyethylene wall is engineered for liquids up to 1.9 times the weight of water. Filled with water (SG 1.0), the contents alone weigh about 83,400 lb; loaded to its full 1.9 SG rating, the tank is engineered for roughly 158,460 lb of contents. Those two numbers tell you everything about the pad and stand you need underneath it: this is a heavy, high-density tank, so the structure carrying it has to be sized for the worst-case loaded weight, not the water weight. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your volume and weight math, and because a cone bottom tank lives on an elevated stand, check the Cone Bottom Tank Stand Compatibility Matrix before you order steel. For the full picture on this exact size, the 10000 Gallon Cone Bottom Tank buyer's guide walks through the layout, and if you decide to step down, the 3000-gallon cone bottom guides cover the smaller footprints.
Chemical compatibility
One caveat before anything else: the resin on this tank is recorded as HDLPE, but the source ends with a question mark - confirm the exact resin with us before committing it to chemical service, because the resin determines what it can safely hold. With the resin and the 1.9 specific-gravity rating both verified, the chemicals below are workable in this tank when paired with the listed fitting and gasket materials. Fitting and gasket selection is not optional - the wrong elastomer fails long before the tank does. Concentrations shown are the rated points; match yours exactly against the OEM chemical-resistance chart, which is concentration- and temperature-specific, before you order.
- 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
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - 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 (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
A few entries break from the PVC/EPDM pattern that covers most of the salts on this list, and those are the ones to slow down on. Sulfuric acid at 98% demands CPVC fittings and Viton gaskets; peracetic acid needs 316SS fittings and Aflas gaskets. Specifying the wrong material on either of those is the most common and most expensive mistake on a chem install.

Freight and ordering
This tank ships LTL from the plant in Converse, TX, with freight quoted live to your ZIP - there is no flat shipping number on a tank this size and weight. Get your number from the Freight Cost Estimator or call 866-418-1777 and we will quote it for you, walk you through fitting and gasket selection for your chemical, and confirm the resin before it ships. See the technical drawing on this page for fitting locations and full dimensions, and have your pad and stand sized for the full loaded weight - roughly 158,460 lb at the 1.9 SG rating - before delivery day.
