The Snyder Industries 11500 Gallon XLPE Cone Bottom Tank is built for full-drain bulk chemical storage where the contents need to evacuate completely and the liquid is heavier than water. It is molded from crosslinked linear polyethylene (XLPE) in black, rated to 1.5 specific gravity, and measures 215 in tall on a 142 in by 142 in footprint. It holds 11,500 gallons; full of water that is 95,910 lb, and at its 1.5 SG rating the maximum contents load reaches 143,865 lb. Those numbers drive everything downstream: the cone stand, the slab, and the support structure all have to carry six figures of load, so confirm your foundation and stand rating against the full contents weight before you order.
Will it work for your application
This is a cone bottom tank, so it must sit in a matching steel stand that supports the cone and lets you fully drain the vessel from the bottom outlet. The molded-in fittings shown on the drawing include a flange outlet, an 18 in PE threaded/vented fitting, a manway with 15 in access, and a 12 in x 13 in fitting. Use the manway with 15 in access for inspection and cleanout, and plan your vent and fill connections around the 18 in PE threaded/vented port. XLPE is a single-wall material, so for full secondary containment you will need a separate basin sized to the contents. To right-size against your fill volume and verify the stand load path, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide, and review the Cone Bottom Tank Stand Compatibility Matrix before pairing a stand. See the technical drawing on this page for exact fitting locations and dimensions.
Chemical compatibility
This tank is crosslinked linear polyethylene (XLPE) rated to 1.5 specific gravity. At that 1.5 SG rating it is compatible with 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). Fittings and gaskets must match the chemical, not just the tank: Aluminum Sulfate, Calcium Chloride, Ferrous Sulfate, Magnesium Chloride, Sodium Carbonate, and Ozonated Water all call for PVC fittings with EPDM gaskets; Acetic Acid and Urea Solution call for PP/PVC fittings with EPDM; and DEF requires 316SS fittings with EPDM. Worth noting: DEF (a 32.5% urea solution) and the listed Urea Solution (50%) are chemically related but spec'd differently here, so don't assume one fitting material covers both. Always verify against the OEM chemical-resistance chart for your specific concentration and storage temperature, since both shift the rating. See Acetic Acid, Aluminum Sulfate, Calcium Chloride, DEF, Ferrous Sulfate, Magnesium Chloride, Sodium Carbonate, Urea Solution, and the full Chemical Compatibility Database.
The mistake to avoid: under-rating the SG
This vessel is rated to 1.5 SG, which covers the chemicals above but is not enough for the denser ones. Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrofluosilicic Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, and Sodium Thiosulfate all require a higher 1.9 SG tank, so do not put any of those in this 1.5-rated vessel; step up to the 1.9 SG-rated XLPE cone bottom equivalent instead. Most of those call for PVC fittings with EPDM, but two are exceptions: Hydrofluosilicic Acid needs PP/PVC fittings with Viton gaskets rather than EPDM, and Propylene Glycol needs PP/316SS fittings. Get the fitting material, gasket, and SG rating right against the OEM chart and your hardware will last as long as the tank.
Freight
This tank ships LTL from Snyder's plant in Lincoln, NE, with freight quoted live to your ZIP. At 215 in tall on a 142 in by 142 in footprint, it is an over-height, oversize load, so those are the dimensions that gate trailer access, permit and escort needs, and unloading reach on site. Use the Freight Cost Estimator for a freight estimate to your ZIP, then line up the unloading equipment for a vessel of this scale before it arrives. For containment sizing, level instrumentation, and hazard labeling on a bulk chemical install, see our guides on 110% containment vs UL-142/SPCC, tank level gauge selection for chemical service, and tank label and signage compliance.
