The Snyder Industries 1000 Gallon 45 Degree Cone Bottom Tank in White is built for full-drain chemical and process service, mounted on a steel stand so gravity empties the steep cone with no residual heel. It carries a 1.9 specific-gravity rating, which is what makes it a true chemical vessel rather than a water tank pressed into duty. The base measures 64 inches across, the tank stands 103 inches tall to the top fitting, and it holds 1,000 gallons in a 64.0 x 64.0 footprint. This is the tank buyers search for as a 1000 gallon cone bottom tank, cone tank, or HDPE cone bottom, and the 45-degree cone is the steep-drain version that clears slurries and settling solids the shallower cones leave behind.
Will this tank work for your application?
Empty footprint is 64.0 x 64.0 inches and the tank stands 103 inches tall, so plan overhead clearance and the height of the supporting stand before you order. Water at 1,000 gallons weighs 8,340 lb; loaded to the full 1.9 SG rating the contents alone reach 15,846 lb. That is 7,506 lb more than the same tank full of water, nearly double, and it is the single most common engineering miss on a high-SG cone tank ordered by someone used to water tanks. Size the stand, pad, and anchor bolts to the rated load, never to water weight. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the gallon-to-weight math against your structure and process flow. The technical drawing on this page shows the fitting layout: a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access. The 18-inch threaded/vented fitting handles offgassing and level changes during fill and draw, and the 15-inch manway access supports interior inspection, cleaning, and the gasket and fitting service you will be doing per the compatibility table below. Confirm each fitting location and elevation against your piping and dosing skid before installation.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific-gravity rating. Confirm the exact resin grade, HDLPE versus XLPE, against the Snyder spec sheet before committing the tank to chemical service, because resin chemistry drives long-term resistance to aggressive oxidizers and acids. The 1.9 SG rating is a structural rating: even the densest chemicals listed here, such as 98% sulfuric acid at roughly 1.84 SG, stay within the tank's rated load, while lighter chemistries leave headroom. Compatibility itself still depends on the chemical, its concentration, temperature, and the fitting and gasket materials you spec, so always verify against the OEM chemical-resistance chart for your exact concentration and operating temperature.
Chemicals confirmed in our compatibility data for this tank's resin and SG rating, with the fitting and gasket materials they require, include: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets, details); Aluminum Sulfate at 50% (PVC, EPDM, details); Calcium Chloride at 40% (PVC, EPDM, details); DEF at 32.5% (316SS, EPDM, details); Ethylene Glycol at 100% (PVC, EPDM, details); Ferric Chloride at 50% (PVC, EPDM, details); Ferric Sulfate at 60% (PVC, EPDM, details); Ferrous Sulfate at 20% (PVC, EPDM, details); Hydrochloric Acid at 37% (PVC, Viton, details); Hydrofluoric Acid at 48% (PP/PVC, Viton, details); Hydrofluosilicic Acid at 26% (PP/PVC, Viton, details); Hydrogen Peroxide at 50% (PVC, Viton, details); Magnesium Chloride at 30% (PVC, EPDM, details); Peracetic Acid at 30% (316SS, Aflas, details); Phosphoric Acid at 85% (PVC, Viton, details); Polyaluminum Chloride (PVC, EPDM, details); Potassium Carbonate at 50% (PVC, EPDM, details); Potassium Hydroxide, saturated (PVC, EPDM, details); Propylene Glycol (PP/316SS, EPDM, details); Sodium Bisulfate (PVC/PP, EPDM, details); Sodium Bisulfite (PVC/PP, EPDM, details); Sodium Carbonate at 30% (PVC, EPDM, details); Sodium Hypochlorite below 16.5% (PVC, Viton, details); Sodium Thiosulfate at 40% (PVC, EPDM, details); Sulfuric Acid at 98% (CPVC, Viton, details); Urea Solution at 50% (PP/PVC, EPDM, details); Zinc Orthophosphate (PP/316SS, EPDM, details); and Ozonated Water up to 10 PPM (PVC, EPDM). Every chemical in our compatibility data for this tank falls within its 1.9 SG rating, so no heavier-rated vessel is required for the chemistries listed. Browse the full Chemical Compatibility Database to match your chemistry, concentration, and gasket spec.
The mistake to avoid
The most common error on a high-SG cone-bottom tank is matching the wrong gasket and fitting metallurgy to an aggressive chemical. Sulfuric Acid at 98% calls for CPVC fittings with Viton, Sodium Hypochlorite and Hydrogen Peroxide also demand Viton over EPDM, and Peracetic Acid needs 316SS with Aflas. An EPDM gasket that is fine on Calcium Chloride will fail fast on those oxidizers. Spec the fitting and gasket material to your exact chemical and concentration, not to a generic chemical-tank default, and resolve the exact resin grade before you fill it.
