The Enduraplas 7011 Gallon Green Cone Bottom Tank is a 7,011-gallon polyethylene bulk-storage vessel with a 144 in by 144 in footprint and an overall height of 141 in. It carries a 1.9 specific-gravity rating, which is the highest standard poly rating available and the number that decides whether this tank fits your chemical, so confirm your product's SG before you order. This is a cone bottom tank built for full drainage and chemical service, and it must sit on a matching cone-bottom stand sized to carry the loaded weight.
Will it work for your application?
Sizing is where most cone-bottom buyers get caught, so run the numbers before you commit. Filled with plain water the contents alone weigh 58,472 lb, and at the tank's full 1.9 SG rating the maximum rated contents weight climbs to 111,096 lb. That higher figure is what your stand, pad, and anchoring must carry, plus the empty tank, so size the foundation to the heaviest product you will ever store, not to water. The 144 x 144 in footprint and that 111,096 lb max load are the two numbers to take to your stand selection: confirm them against our Cone Bottom Tank Stand Compatibility Matrix for Norwesco, Snyder, and Enduraplas. Use the Tank Sizing Calculator and the Tank Sizing Guide to translate gallons and SG into the weight your support structure has to hold. Dimensional details are shown on the technical drawing on this page.
Chemical compatibility
This is a polyethylene tank rated at 1.9 specific gravity, which covers essentially every chemical in the list below with margin to spare (the heaviest by SG are 98% sulfuric acid near 1.84 and 50% ferric chloride near 1.5). Its resin is recorded as HDLPE but not yet confirmed, so check the exact resin grade with us or against the OEM chart before chemical service. The tank ships as a bare vessel: no bulkhead fittings, vents, or gaskets are included, so the fitting and gasket materials called out below must be specified and ordered to match your exact chemical and concentration. Confirmed-compatible chemicals for this tank include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), 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/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (<16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Match gaskets by chemical class, because a gasket mismatch is the most common failure point: oxidizers, chlorine, and strong acids (sodium hypochlorite, hydrochloric, sulfuric, phosphoric, hydrogen peroxide, hydrofluoric) call for Viton, with CPVC fittings on 98% sulfuric; DEF and peracetic acid call for 316SS, with an Aflas gasket on peracetic acid; salts, bases, and glycols run on PVC or PP with EPDM. Always confirm against the OEM chemical-resistance chart for your exact concentration and temperature, and cross-check our Chemical Compatibility Database before ordering.
Labeling and compliance
Once this tank is in service, bulk polyethylene storage carries labeling and signage obligations that inspectors check. Get your NFPA 704 diamond, GHS pictograms, DOT placards, and pipe marking right the first time using our guide to tank label and signage compliance for bulk polyethylene storage. For top-side plumbing, plan vent, fill, level, and drain placement up front with our guide on tank top fitting placement strategy, and choose monitoring hardware with the tank level gauge selection guide.
Freight
This Enduraplas cone bottom tank ships LTL freight from the nearest of two plants, Converse, TX or Neche, ND, with the rate quoted live to your ZIP code. At this size the tank ships separately from its stand, so plan for offloading equipment and clear site access. Get a real number with our Freight Cost Estimator, or call 866-418-1777 and we will line up the freight and the matching cone-bottom stand for your install.
