4400 Gallon 30 Degree Plastic Cone Bottom Tank in White

The 4400 Gallon 30 Degree Plastic Cone Bottom Tank from Snyder Industries is a 1.5 specific-gravity cone-bottom vessel built for full-drain chemical and process work where you need every gallon to evacuate through the cone. Molded in white polyethylene, this 30-degree cone tank stands 199.5 inches tall on a 90 x 90 inch footprint and holds 4,400 gallons. The 30-degree cone angle is what drives complete drainage, so the tank suits batching, mixing, and metered-dosing operations that can't tolerate a residual heel in a flat-bottom tank. Quick spec read: 4,400 gal / 30 deg cone / 199.5 in H / 90 in dia / white PE / 1.5 SG. This page answers the three things that matter before you buy - whether it fits your job, how it ships, and the one mistake to avoid with a cone tank at this specific gravity.

Will it work for your job

The 1.5 SG rating means this tank is engineered to carry contents up to 1.5 times the weight of water. Filled with water, contents weigh about 36,696 lb; loaded to the full 1.5 SG rating, the supported contents weight reaches 55,044 lb. Per the technical drawing on this page, the tank carries a top FLANGE, an 18-inch PE threaded/vented fitting that serves as the fill and vent path, and a MANWAY with a 15-inch access opening - meaning internal mixing gear, cleaning tools, or inspection access is limited to a 15-inch entry. A cone-bottom tank of this size is not self-supporting and must sit in a matching steel or poly cone stand. Size that stand to the LOADED weight at your actual fluid SG - interpolate between 36,696 lb at 1.0 SG (water) and 55,044 lb at the full 1.5 SG rating - so the stand and pad carry the real working load, not just the empty tank. Run those numbers with the Tank Sizing Calculator and confirm the cone tank footprint and stand height fit your space with the Tank Sizing Guide.

Chemical compatibility

This is a polyethylene tank rated to 1.5 specific gravity. The tank resin is recorded as HDLPE with a question mark - confirm HDLPE versus XLPE (crosslinked) with us before committing to any chemical on the compatible list, because the two resins differ in chemical resistance and every compatibility row below assumes a confirmed resin. At the 1.5 SG rating, this tank suits Acetic Acid at 60%, Aluminum Sulfate at 50%, Calcium Chloride at 40%, DEF at 32.5%, Ferrous Sulfate at 20%, Magnesium Chloride at 30%, Sodium Carbonate at 30%, Urea Solution at 50%, and Ozonated Water up to 10 PPM. Most of these call for PVC fittings with EPDM gaskets; Acetic Acid and Urea Solution accept PP or PVC fittings, and DEF requires 316 stainless fittings, all with EPDM gaskets. Always confirm against the OEM chemical-resistance chart for your exact concentration and operating temperature - resistance is concentration- and temperature-specific.

Chemicals that need a higher-SG tank

Several common chemicals exceed what a 1.5 SG tank should hold and require a 1.9 SG-rated tank instead. If your chemical is on this list, this 1.5 SG tank is NOT rated for it - request the 1.9 SG version. The list includes Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. Note that Sodium Hypochlorite, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Phosphoric Acid, Sulfuric Acid, and Hydrogen Peroxide also call for Viton gaskets rather than EPDM; Peracetic Acid calls for 316 stainless fittings with an Aflas gasket; and Sulfuric Acid needs CPVC fittings. If your application is on this list, call us at 866-418-1777 and we'll size you into the correct higher-SG tank.

The mistake to avoid

The single biggest error on a tank like this is matching by gallons and shape alone while ignoring the specific gravity of your fluid. A cone-bottom white poly tank at 1.5 SG is the right pick for the compatible chemicals above, but loading it with a denser fluid - or one from the higher-SG list - shortens its life and risks failure under load. Pair that with the resin confirmation (HDLPE versus XLPE) and the correct fitting and gasket materials from the chart, and you've covered what trips most buyers up.
