The Enduraplas 6000 Gallon Green Cone Bottom Tank with Stand (SKU THC06000KG) is a full-drain vessel built for chemical batching and storage where you need the tank to empty toward a single low point. Molded in green polyethylene and rated to a 1.9 specific gravity, it stands 204" (17 ft) tall on its included stand over a 110" diameter footprint, with an empty weight of 1,100 lb. Fluid leaves through a 3" PP female NPT bulkhead outlet at the cone apex, and you fill and service through a 16" threaded vented manway up top. It carries an FDA Approved rating. That 1.9 rating is the top of the poly range — there is no heavier plastic tank to wait for — so match your product's specific gravity to 1.9 before you buy this cone bottom tank with stand.
Will it hold your load?
Capacity is 6,000 gallons. Plain water at that volume weighs about 50,040 lb; loaded to the tank's full 1.9 SG rating, contents run up to roughly 95,076 lb. That contents figure is what the stand and your slab have to carry, so size the pad and anchoring to the rated number, not the water number. Run your fluid through the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 6000 gallon volume and weight work for your footprint. The full 110" diameter footprint needs a level, engineered base, and at 204" (17 ft) overall you should confirm indoor overhead clearance and a safe way to reach the top manway for filling and service before ordering. See the technical drawing on this page for the cone angle, dimensions, and fitting locations.
Chemical compatibility
This is an HDLPE-family polyethylene tank rated to 1.9 specific gravity, but the resin code carries a "?" in our data — confirm HDLPE vs. XLPE with us before you commit it to chemical service, since the two resins tolerate different chemistries. The compatibility ratings below come from a Snyder Industries OEM chemical resistance chart used here as a polyethylene reference; because this is an Enduraplas tank, confirm your exact service against Enduraplas and through us before ordering. The chart is concentration- and temperature-specific, so verify your exact chemical, concentration, temperature, and the fitting and gasket materials first. Note the included outlet is a 3" PP bulkhead — for any service below that calls for PVC, CPVC, or 316SS, plan to swap the stock outlet to the matching fitting material.
At the 1.9 SG rating this tank supports (fitting / gasket noted): Ethylene Glycol 100% (PVC / EPDM), Ferric Chloride 50% (PVC / EPDM), Ferric Sulfate 60% (PVC / EPDM), Hydrochloric Acid 37% (PVC / Viton), Hydrofluoric Acid 48% (PP or PVC / Viton), Hydrofluosilicic Acid 26% (PP or PVC / Viton), Hydrogen Peroxide 50% (PVC / Viton), Peracetic Acid 30% (316SS / Aflas), Phosphoric Acid 85% (PVC / Viton), Polyaluminum Chloride (PVC / EPDM), Potassium Carbonate 50% (PVC / EPDM), Potassium Hydroxide saturated (PVC / EPDM), Propylene Glycol (PP or 316SS / EPDM), Sodium Bisulfate (PVC or PP / EPDM), Sodium Bisulfite (PVC or PP / EPDM), Sodium Hypochlorite under 16.5% (PVC / Viton), Sodium Thiosulfate 40% (PVC / EPDM), Sulfuric Acid 98% (CPVC / Viton), and Zinc Orthophosphate (PP or 316SS / EPDM).
Several chemicals are compatible with this tank but call for a specific gasket or fitting rather than a heavier tank — for example Acetic Acid 60%, Aluminum Sulfate 50%, Calcium Chloride 40%, DEF 32.5% (316SS / EPDM), Magnesium Chloride 30%, Sodium Carbonate 30%, Ferrous Sulfate 20%, Urea Solution 50% (PP or PVC / EPDM), and Ozonated Water up to 10 PPM — all list required SG ratings at or below this tank's 1.9. Cross-check your exact service against the full Chemical Compatibility Database, and remember the chart is concentration- and temperature-specific.
