The Snyder Industries 500 Gallon 45 Degree HDPE Cone Bottom Tank in White is built for service where the contents drain themselves out the bottom and you walk away with a clean tank. The steep 45-degree cone discharges thick slurries, settled solids, and viscous chemistry far more completely than a shallow cone, and the 1.9 specific-gravity rating means this cone bottom tank is engineered to hold dense, heavy liquids that would overstress a standard water-grade vessel. Molded by Snyder Industries in white polyethylene, it stands 63 inches tall on a 64 x 64 inch footprint. A cone bottom cannot stand on its own, so plan on a matching cone stand or steel structure to carry the discharge geometry off the floor - that support is not included with the tank and should be in your budget and your freight dimensions.
Will it work for your application
This is a 500-gallon HDPE cone tank rated to 1.9 specific gravity, which is the spec that separates a real chemical-service vessel from a water tank. Filled with plain water it carries about 4,170 pounds; at its maximum rated contents it is engineered to hold up to 7,923 pounds, so your full-load weight depends entirely on the density of what you store. Treat 1.9 SG as a hard ceiling - do not put a liquid heavier than that in this tank, and use both weight numbers when you spec the stand and the slab. The technical drawing on this page documents the molded fittings: a flange, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access. That 15-inch manway is your cleanout and inspection port, which is exactly what slurry service needs, and the vented fitting prevents vacuum collapse when the 45-degree cone drains fast through the bottom outlet. If you are weighing this against other cone angles or capacities, the Tank Sizing Calculator and Tank Sizing Guide will confirm the volume and weight math for your liquid, and our 500 Gallon 45 Degree Cone Bottom Tank buyer's guide walks through the trade-offs versus the 30-degree version.
Chemical compatibility
This tank is molded from polyethylene with a 1.9 specific-gravity rating, which gives it the wall thickness to handle a wide range of dense industrial chemistry. The base resin is listed as HDLPE, but because that field is unconfirmed, confirm HDLPE versus XLPE with us before committing this tank to chemical service. Verified-compatible chemicals from the OEM chemical-resistance chart, which is concentration- and temperature-specific, include 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), sodium hypochlorite (under 16.5%, PVC, Viton), hydrogen peroxide (50%, PVC, Viton), ferric chloride (50%, PVC, EPDM), ferric sulfate (60%, PVC, EPDM), aluminum sulfate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), sodium carbonate (30%, PVC, EPDM), ethylene glycol (100%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM), among others. Two cases change your install bill of materials: DEF (32.5%, 316SS fittings, EPDM) and peracetic acid (30%, 316SS, Aflas) both call for stainless-steel fittings rather than PVC, and peracetic acid needs Aflas gaskets - not the Viton or EPDM the other chemicals use. In short, the chart points to three gasket regimes: Viton on the strong oxidizers and concentrated acids, EPDM on the salts and glycols, and Aflas on peracetic acid. Match the fitting and gasket to your specific chemical, and always verify your exact concentration and operating temperature against the full chart and our Chemical Compatibility Database before ordering.
Freight and ordering
This cone bottom tank ships LTL freight from the Snyder Industries plant in Lincoln, Nebraska, and freight is quoted live to your ZIP rather than baked into the list price. Remember the tank ships without a stand, so factor the cone stand into your freight cost and dimensions. Get a freight number to your delivery address with the Freight Cost Estimator, or call us at 866-418-1777 and we will confirm the fittings, the right cone stand, and the gasket package for your chemistry before the tank leaves the line.
