The Snyder Industries 11500 Gallon XLPE Heavy Duty Cone Bottom Tank is a full-drain crosslinked polyethylene tank built for aggressive chemical storage and complete batch discharge. Molded in black crosslinked linear polyethylene with a 1.9 specific gravity rating, it holds 11,500 gallons in a 142-inch by 142-inch footprint and stands 215 inches tall. The cone bottom drains to a flange outlet so you empty the tank fully, without manual pumping or product left sitting on a flat floor.
Will it work for your application?
The 1.9 specific gravity rating is the headline spec, and it matters: it tells you the heaviest liquid this XLPE shell is rated to hold. Filled with water the tank weighs about 95,910 pounds; loaded to its maximum rated contents it carries up to 182,229 pounds, so your stand, pad, and cone support structure must be engineered for a fully loaded high-gravity liquid, not for water. The factory fitting package includes a flange outlet, an 18-inch PE threaded and vented top fitting, a manway with 15-inch access, and a 12-inch by 13-inch fitting. That 15-inch manway access is a real constraint for internal inspection, agitator service, and confined-space entry on a 215-inch-tall tank, so check it against your inspection and mixing plan before you order. Exact fitting positions, port elevations, and cone angle are shown on the technical drawing on this page; confirm them against your piping and any agitator or fill-line layout. If you are still working volume against batch size or chemical inventory, the Tank Sizing Calculator and Tank Sizing Guide will help you right-size before committing to this 11,500-gallon cone tank.
Chemical compatibility
This is an XLPE (crosslinked polyethylene) tank rated to 1.9 specific gravity. The crosslinked resin is the right call for many oxidizers and concentrated chemistries where standard HDPE would be marginal; for the crosslinked-versus-linear tradeoff, read Snyder XLPE vs HDPE: When Crosslinking Matters for Chemistry Duty. The chemistries below are commonly stored in this resin and SG class, with the fitting and gasket materials that typically suit them. Note that the tank's factory ports are poly (PE); the downstream fittings and gaskets named here are components you spec and source separately to match your chemical. Always confirm against the OEM chemical-resistance chart at your specific concentration and temperature, since both shift compatibility.
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Most of these chemistries run on PVC fittings with EPDM gaskets, but three deviate and are worth flagging: DEF wants 316 stainless fittings, hydrofluosilicic acid wants Viton gaskets rather than EPDM, and propylene glycol wants PP or 316SS. Match the fitting and gasket metallurgy to your chemical, not just the tank. Full details and other chemistries are in our Chemical Compatibility Database.
The mistake to avoid
The expensive error on a high-gravity cone tank is treating the 1.9 SG rating as a formality and undersizing the support. The cone bottom carries the entire 182,229-pound rated load through the cone and stand, so the stand must be matched to both this tank's cone geometry and your liquid's gravity. For stand selection, see the Cone Bottom Tank Stand Compatibility Matrix, and for monitoring a tank you cannot easily eyeball, the level-gauge selection guide walks through radar, ultrasonic, hydrostatic, and magnetostrictive options for chemical service. If you also need secondary containment, the Snyder Captor Plus 110% Containment vs UL-142 comparison covers the regulatory tradeoffs.
