The Enduraplas 6000 Gallon White Cone Bottom Tank with Stand (SKU THC06000KW) is a full-drain vessel built for chemical batching, mixing, and metering where you need the tank to empty completely. It stands 204 inches tall on its integrated stand over a 110-inch-diameter footprint, molded from polyethylene in natural white with a 1.9 specific gravity rating, an empty weight of 1,100 lb, and FDA-approved material. It ships from the plant with a 3-inch PP female NPT bulkhead outlet at the cone tip and a 16-inch threaded vented manway up top. Because the cone geometry and elevated stand let gravity pull the last of the batch to the outlet, this is a common pick for anyone searching a 6000 gallon cone bottom tank with a stand for process and chemical duty.
Will it hold your process load
Size to the weight, not just the gallons. Filled with water this tank carries about 50,040 lb; against its 1.9 SG rating the maximum rated contents weight is roughly 95,076 lb. That spread is the whole reason for the SG number: the fuller you load a dense chemical, the more the stand and the ground beneath it have to carry. At 1.9 SG this is the top density rating in the poly line, so there is no higher-SG tank to step up to - if your chemistry needs more, the answer is a different material, not a heavier poly tank. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you set it, and confirm the pad can bear a fully loaded cone-bottom stand. The 3-inch PP bulkhead handles the drain; the 16-inch vented manway gives you fill and inspection access while keeping the tank vented during transfer.
Chemical compatibility
This tank is polyethylene rated to 1.9 specific gravity. The resin is recorded as HDLPE with a query flag, so confirm HDLPE versus XLPE (cross-linked) with us before you commit it to chemical service - the two behave differently against certain chemistries. Compatibility below is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; confirm your exact chemical, concentration, temperature, and fitting plus gasket material before ordering. At the 1.9 SG rating this tank supports, the chart lists: Ethylene Glycol (100%, PVC fittings, EPDM gaskets), Ferric Chloride (50%, PVC/EPDM), Ferric Sulfate (60%, PVC/EPDM), Hydrochloric Acid (37%, PVC/Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC/Viton), Peracetic Acid (30%, 316SS fittings, Aflas gaskets), Phosphoric Acid (85%, PVC/Viton), Polyaluminum Chloride (PVC/EPDM), Potassium Carbonate (50%, PVC/EPDM), Potassium Hydroxide (saturated, PVC/EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Hypochlorite (under 16.5%, PVC/Viton), Sodium Thiosulfate (40%, PVC/EPDM), Sulfuric Acid (98%, CPVC fittings, Viton gaskets), and Zinc Orthophosphate (PP/316SS, EPDM). Several chemistries the chart clears at lower SG tanks - Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), DEF (32.5%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Sodium Carbonate (30%), Urea Solution (50%), and Ozonated Water (up to 10 PPM) - are also cleared here since this tank's 1.9 rating exceeds their required SG. See the technical drawing on this page for the cone angle and fitting placement, and cross-check every line against the OEM chart and our Chemical Compatibility Database.
Match the outlet to your chemistry
The tank ships with a 3-inch PP bulkhead outlet, and that stock fitting is not right for every chemistry on the chart. For PP/EPDM services - the glycols, urea solution, DEF, and the sulfate salts - the factory PP outlet is a match with only a gasket check, which makes this a clean fit for the very common DEF and urea batching duty. But the acids and oxidizers on the list require swapping the outlet before service: Sulfuric Acid at 98% needs a CPVC fitting with a Viton gasket; Hydrochloric Acid, Hydrofluoric Acid, Hydrogen Peroxide, and Sodium Hypochlorite call for PVC with Viton; and Peracetic Acid needs a 316SS fitting with an Aflas gasket. Note that Aflas is a specialty seal specified only for peracetic acid here - it is not a shelf EPDM or Viton, so plan for it if you batch PAA. If you are storing sodium hypochlorite, the 16-inch vented manway matters: bleach off-gasses, and passive venting through the manway helps manage that pressure during storage and transfer.
The mistake to avoid
Do not order this tank for chemical duty without first confirming the resin. The pack lists the resin as HDLPE with a question mark; HDLPE and cross-linked (XLPE) polyethylene resist certain acids and oxidizers differently, and guessing wrong is how a tank fails early. Call 866-418-1777 and give us the exact chemical, concentration, and temperature so we confirm the resin, the SG headroom, and the correct fitting and gasket (PVC, CPVC, PP, or 316SS with EPDM, Viton, or Aflas) before you buy. Choosing the stand matters too - our stand selection decision tree and the stand compatibility matrix walk through steel versus poly for cone-bottom tanks.
