The Snyder Industries 6000 Gallon Cone Bottom Tank (SKU 5280200N49) is a black polyethylene cone bottom tank built for full-drain chemical batching and process work, where the sloped floor sends every gallon to the apex outlet instead of leaving heel in a flat bottom. It measures 142 inches in diameter and stands 136 inches tall on a 142.0 x 142.0 inch footprint, and it carries a 1.5 specific gravity rating, so it is engineered to hold chemistries up to 1.5 SG at full capacity. A cone bottom tank drains through its tip, so it has to sit in a support stand or structure - plan that around the full load before the tank arrives, and use the technical drawing on this page to read the cone angle and the outlet elevation off the pad.
Will this cone bottom tank work for your application?
The 1.5 SG rating governs what you can safely store. Filled with plain water this tank carries 50,040 lb, and at its maximum rated contents it carries 75,060 lb (6,000 gallons at 1.5 SG) - size your stand, pad, and anchoring to that 75,060 lb figure, not the water number. Factory fittings per the technical drawing on this page include a FLANGE, a 12" x 13" fitting, an 18" PE threaded/vented fitting, and a manway with 15" access. The 18" vented fitting matters on off-gassing chemistries so pressure does not build, and the 15"-access manway gives you entry for cleaning and inspection between batches. Confirm fitting locations and elevations against your piping plan from the drawing, and run your dimensions through the Tank Sizing Calculator and Tank Sizing Guide before you commit.
Chemical compatibility
This tank is molded in polyethylene with a 1.5 specific gravity rating. The resin is HDLPE, but the grade carries a question mark in our data - confirm HDLPE versus XLPE construction before placing any chemical into service, because the two resins behave differently with oxidizers and solvents. Against the OEM chemical-resistance chart, which is concentration- and temperature-specific, the following are compatible with a 1.5 SG cone bottom tank at the listed concentrations: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS fittings, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Magnesium Chloride at 30% (PVC, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Urea Solution at 50% (PP/PVC, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Match your bulkhead fitting and gasket materials to the chemical, not just the tank shell - the molded PE shell is one part of the compatibility picture and the fitting/gasket is the other.
Chemistries that need a higher-SG tank
Several common process chemicals exceed what a 1.5 SG tank should carry and require a 1.9 SG tank instead - an honest call before you buy the wrong shell. These include Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid (Viton gaskets), Hydrofluoric Acid (Viton), Hydrofluosilicic Acid (Viton), Hydrogen Peroxide (Viton), Peracetic Acid (316SS fittings, Aflas), Phosphoric Acid (Viton), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite (Viton), Sodium Thiosulfate, Sulfuric Acid (CPVC, Viton), and Zinc Orthophosphate. Notice how the gasket and fitting materials escalate with the aggressiveness of the chemistry - EPDM gives way to Viton on the acids, and the most aggressive services like peracetic acid jump to 316SS fittings with Aflas gaskets. Verify any chemistry on the full Chemical Compatibility Database before ordering. If you are still right-sizing storage or specifying level monitoring, the 6000 Gallon 15 Degree Cone Bottom Tank buyer's guide, the cone bottom stand compatibility matrix, and the tank level gauge selection guide walk through the decisions that bite later.
