The Snyder Industries 11500 Gallon XLPE Cone Bottom Tank is a crosslinked linear polyethylene vessel built for full-drain chemical service, holding 11,500 gallons in a 142-inch by 142-inch footprint that stands 215 inches tall. The crosslinked (XLPE) resin and the 1.5 specific gravity rating are the two numbers that decide whether this cone bottom tank fits your process, so read both against your chemical before you commit. The natural white wall lets operators eyeball product level through the tank, and the cone bottom geometry drains the vessel completely - no heel left sitting in the bottom.
Will it work for your application?
Filled with water this tank carries 95,910 lb; at its maximum 1.5 specific gravity rating it is engineered to hold up to 143,865 lb of contents. Those weights drive your stand, foundation, and anchoring decisions - run them through the Tank Sizing Calculator and the Tank Sizing Guide before you spec a steel stand, and check the Cone Bottom Tank Stand Compatibility Matrix for Snyder-specific stand pairing. Fittings on this tank include a flange, an 18" PE threaded/vented fitting, a 12" x 13" fitting, and a manway with 15" access - that 15-inch manway opening is what governs whether a person or cleaning equipment can reach the interior of a 215-inch-tall vessel for inspection and service, so weigh it against your maintenance plan. Confirm exact fitting placement and orientation against the technical drawing on this page. For level monitoring on a cone tank this tall, see our guide on Tank Level Gauge Selection for Chemical Service.
Chemical compatibility
This is an XLPE (crosslinked polyethylene) tank rated to 1.5 specific gravity, and you should always verify your specific chemical, concentration, and temperature against our Chemical Compatibility Database first. Within that 1.5 SG ceiling, our compatibility data supports the following at the listed concentrations: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Urea Solution (50%, PP/PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). EPDM gaskets cover this entire compatible set; match the fitting material to your chemical exactly - DEF at 32.5% takes 316SS hardware, not the PVC default, while its higher-concentration cousin Urea Solution at 50% runs on PP/PVC. That hardware distinction matters more than the tank wall on a urea-family install.
Some heavier chemicals exceed the 1.5 SG rating of this tank and need a higher-SG (1.9) tank instead, and several also change the hardware spec: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrofluosilicic Acid (PP/PVC fittings and Viton gaskets - the one gasket exception in this whole set), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol (PP/316SS fittings), and Sodium Thiosulfate. If your application is on that list, do not order this 1.5 SG tank - step up to the 1.9 SG version and call 866-418-1777 for that quote.
The mistake to avoid
The single most common error on a tank this size is mismatching the resin and SG rating to the chemical. This is a 1.5 SG XLPE tank - it will not safely hold a 1.9 SG chemical, so confirm both the specific gravity and the resin against your chemical's data sheet before you order. If you are storing a bulk chemical that triggers labeling or hazard-communication requirements, review tank label and signage compliance for bulk polyethylene storage. For secondary containment questions on a vessel this large, the Snyder Captor Plus 110% containment vs UL-142 / SPCC comparison walks through the options.
This tank ships LTL freight from Snyder's plant in Lincoln, NE, with the rate quoted live to your ZIP - get a number in seconds with our Freight Cost Estimator, or call 866-418-1777 to talk through fittings, stands, and delivery. At 11,500 gallons this is an oversized freight load, so the sooner we have your delivery ZIP and site access details, the tighter the quote.
