The Enduraplas 6000 Gallon White Cone Bottom Tank is a high-specific-gravity cone-bottom vessel built for full-drain batch processing, where a sloped floor self-empties product between cycles. Molded in natural white polyethylene with a 1.9 specific gravity rating, it carries a 6,000 gallon working capacity on a 110 x 110 inch footprint and stands 195 inches tall. That 1.9 SG rating is the reason to choose this tank for chemical service: it is rated to hold contents weighing up to 95,076 lb, well beyond the 50,040 lb of a full water load, which is what lets it safely carry dense fluids that would overstress a standard 1.0-1.5 SG tank. It also sits at the top of the SG range in our data - there is no higher-SG cone tank to step up to, so for dense chemical service this is already the correct spec, not a tank to upsell past.
Will it work for your application?
At 6,000 gallons on a 110-inch square footprint and 195 inches of height, this cone tank needs a matched stand to support the cone and elevate the bottom outlet for gravity discharge - the cone shape does not free-stand. Verify your slab, overhead clearance, and stand selection before ordering; our Cone Bottom Tank Stand Compatibility Matrix covers Enduraplas, Norwesco, and Snyder stand pairings, and the 6,000 Gallon Cone Bottom Tank Buyer's Guide walks through sizing decisions for this class. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the 6000-gallon cone tank matches your throughput. See the technical drawing on this page for fitting locations and dimensional detail.
Chemical compatibility
This tank is molded in polyethylene with a 1.9 specific-gravity rating. The exact resin grade is not confirmed in our data - confirm HDLPE versus XLPE (cross-linked) construction with us before committing to chemical service, because the two resins differ significantly in resistance to certain oxidizers and solvents. The cone geometry and high SG suit this tank to settling salts and dense brines - calcium and magnesium chloride, the sulfate coagulants, carbonates, and glycols - where the sloped floor fully self-drains heavy settling solids and the 1.9 rating carries the weight. Most of those run on EPDM gaskets; match the elastomer to the chemical, not just the tank. Based on our chemical compatibility data - which is concentration- and temperature-specific - this tank is suited to a wide range of process chemicals when paired with the correct hardware:
- 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
The oxidizer and strong-acid set behaves differently: hydrogen peroxide (50%), sodium hypochlorite (<16.5%), and phosphoric acid (85%) require Viton, 98% sulfuric acid requires CPVC fittings with Viton, and peracetic acid requires Aflas - not the default EPDM. Matching the wrong elastomer is the most common cone-tank mistake. Confirm every selection against the chemical-resistance data at your specific concentration and operating temperature, and browse our full Chemical Compatibility Database before finalizing the build.
The mistake to avoid
The 1.9 SG rating is the hard requirement here - do not down-spec to a lower-SG cone tank to save money if your fluid is denser than water. At 6,000 gallons, a 1.5 SG dense chemical can exceed the wall and seam strength of a tank not rated for it. Two more traps in these facts: DEF (32.5%) and urea solution (50%) need 316SS or PP fitting hardware, not PVC - spec'ing PVC for DEF is a real error - and the resin grade is not assumed, so get HDLPE versus XLPE confirmed for your chemical before you buy. Note also that this tank ships without a pre-configured fitting package; the outlet, gasket, and bulkhead hardware are selected per chemical from the chart above, so confirm the package by phone before ordering.
