The Snyder Industries 4600 Gallon 15 Degree Plastic Cone Bottom Tank (SKU SII-8050100N45) is a closed-top, 1.9 specific-gravity polyethylene cone bottom tank built for full-drain bulk chemical service - including strong acids and oxidizers at high concentration, from 98% sulfuric to 50% hydrogen peroxide. Standing 123 inches tall on a 102 x 102 inch footprint, the 15-degree cone discharges contents completely without a flat heel, which is exactly what you want for batching, settling, and clean changeovers between products. At a 1.9 SG rating - Snyder's heaviest standard rating for this cone line - this tank carries dense liquids that water-grade tanks cannot safely hold.
Will it hold what you're storing?
Full of plain water this cone tank weighs about 38,364 lb, and it is rated to a maximum contents weight of 72,892 lb - that gap is what the 1.9 SG figure buys you: headroom for heavy acids and concentrated salts up to that density. The cone-bottom design cannot sit on a slab; the full 123-inch closed-top tank must drop into a matched steel stand, so plan for the 102 x 102 inch stand footprint plus clear overhead height for fill and vent access. Before you order a stand, confirm fit using the Cone Bottom Tank Stand Compatibility Matrix and the Tank Sizing Calculator; the Tank Sizing Guide walks through matching capacity to refill cycles. For overall dimensions and the cone discharge geometry, see the technical drawing on this page.
Chemical compatibility
The resin grade for this Snyder cone tank is listed in our data with a "?" - confirm HDLPE versus XLPE with us at 866-418-1777 before committing to chemical service, since that distinction is what decides the strong oxidizers on this list (98% sulfuric, 50% hydrogen peroxide, sodium hypochlorite, peracetic acid). This tank is rated to 1.9 specific gravity. Compatibility always depends on concentration and temperature, so verify your exact service against Snyder's published chemical-resistance chart, which is concentration- and temperature-specific.
Within the OEM chart, this tank is suited to a broad chemical-processing and water-treatment range at the listed concentrations, including Sulfuric Acid (98%, CPVC fittings, Viton gaskets), Hydrochloric Acid (37%, PVC, Viton), Phosphoric Acid (85%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Acetic Acid (60%, PP/PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Hydrogen Peroxide (50%, PVC, Viton), Sodium Hypochlorite (<16.5%, PVC, Viton), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Aluminum Sulfate (50%, PVC, EPDM), Polyaluminum Chloride (PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Thiosulfate (40%, PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), DEF (32.5%, 316SS, EPDM), Urea Solution (50%, PP/PVC, EPDM), Ethylene Glycol (100%, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Match fitting and gasket materials to the chemical exactly as listed - swapping an EPDM gasket onto an oxidizer that requires Viton or Aflas is the most common field mistake on a tank like this. Full concentration and temperature detail lives in our Chemical Compatibility Database. For products denser than 1.9 SG, call us before ordering rather than assuming this tank covers them.
The mistake to avoid
The trap on a 1.9 SG cone tank this size is undersizing the support. The cone carries no weight on the ground - all of it transfers to the stand legs and pad - so a stand rated for water service can be overloaded by a heavy chemical at this 72,892 lb maximum contents weight. Spec the stand to the actual density of your product, not to the tank's water weight. One more gap to close before you order: this tank's standard fitting configuration is not listed in our data, so call 866-418-1777 to confirm bulkhead, outlet, and top-fitting options - with a closed-top cone, vent, fill, level, and drain placement is hard to change after install. The tank-top fitting placement guide and the 15-vs-30-vs-45-degree cone selection guide cover both decisions.
