The Snyder Industries 11500 Gallon XLPE Heavy Duty Cone Bottom Tank is built for full-drain chemical metering and storage where solids settling, batch mixing, and complete emptying matter. Molded in crosslinked linear polyethylene (XLPE) in natural white, it carries a 1.9 specific gravity rating, so it is engineered to hold dense, concentrated chemistries up to that gravity rather than just water. At 11,500 gallons this is a serious bulk vessel: roughly 215 inches tall (about 17.9 feet) on a 142 x 142 inch footprint (about 11.8 feet square), with full water weight near 95,910 lb and a maximum rated contents weight of about 182,229 lb at the 1.9 SG limit. The 17.9-foot height typically exceeds standard building door and ceiling clearances, so confirm overhead access and rigging before delivery, and plan an engineered pad for the load. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm working volume and weight against your space, and review the cone bottom tank stand compatibility matrix before you order the stand.
Fittings and configuration
This cone bottom tank is configured with a flange, an 18-inch PE threaded/vented fitting, a manway with 15-inch access, and a 12 x 13 inch fitting, as shown on the technical drawing on this page. The 15-inch manway access supports inspection, cleaning, and entry for maintenance, while the vented threaded fitting handles fill and pressure relief during transfer. Our data does not specify the flange size or the exact purpose and orientation of the 12 x 13 inch fitting - on a full-drain cone tank the cone discharge is the single most important spec, so call 866-418-1777 to confirm the cone outlet size before you order valves and bulkheads. Verify all fitting positions and sizes against the technical drawing before piping the tank, and match your bulkhead, valve, and gasket materials to the chemistry below. For high-level monitoring on a vessel this size, the tank level gauge selection guide for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options.
Chemical compatibility
This tank is molded in XLPE with a 1.9 specific gravity rating, which is what lets it carry heavier concentrated chemistries than a standard water-grade tank. Always confirm chemistry against the manufacturer's chemical-resistance chart at your specific concentration and temperature, because compatibility is concentration- and temperature-dependent. Fittings and gaskets must be specified to match the chemical, not just the tank wall. Based on the compatibility data for this tank, the following are supported with the noted fitting and gasket materials: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrofluosilicic Acid (26%, PP/PVC fittings, Viton gaskets), Magnesium Chloride (30%, PVC, EPDM), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS fittings, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Thiosulfate (40%, PVC, EPDM), Urea Solution (50%, PP/PVC fittings, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Note the material exceptions: most services pair with PVC fittings and EPDM gaskets, but hydrofluosilicic acid requires a Viton gasket, and DEF and propylene glycol require 316SS fittings rather than PVC - do not default the whole install to PVC/EPDM. The DEF (32.5%) and urea solution (50%) listings make this a practical choice for diesel exhaust fluid storage and blending, but DEF specifically requires 316SS-wetted fittings, so blending DEF through PVC plumbing would be a spec error. For the full picture and to cross-check your exact concentration, see the Chemical Compatibility Database and the OEM chemical-resistance chart. If you are weighing crosslinked versus linear polyethylene for aggressive service, the guide on Snyder XLPE vs HDPE explains when crosslinking earns its keep, and for secondary containment requirements the Snyder Captor Plus 110% containment comparison covers SPCC planning.
Freight and ordering
This 11,500 gallon Snyder cone bottom tank ships LTL freight from the Lincoln, NE plant, quoted live to your ZIP code. Given its 215-inch height and 142 x 142 inch footprint it moves as an oversized, dedicated heavy load, so get an accurate number with the Freight Cost Estimator (which will confirm the shipping weight for your lane) before you commit, and remember the listed price is the tank only, with freight quoted separately. To confirm the cone outlet size, fittings, cone stand, or the 1.9 SG rating against your chemistry and delivery logistics, call 866-418-1777 and we will spec the right configuration for your install.
