The 65 Gallon 30 Degree HDPE Cone Bottom Tank from Snyder Industries is built for batch chemical work where you need every drop to drain. Molded in white High Density Linear Polyethylene with a 1.9 specific gravity rating, this 65-gallon cone tank stands 37 inches tall on a 30.25 x 30.0 inch footprint, and the 30-degree cone bottom forces complete gravity discharge of heavy solutions like ferric chloride or sulfuric acid. That 1.9 SG rating is the headline number: it means the wall is engineered to hold liquids up to 1.9 times the density of water, which is what separates a true chemical cone tank from a light-duty water unit.
Will it work for your job?
Filled with plain water this tank carries about 542 lb; rated to its full 1.9 specific gravity, it is built to support up to 1,030 lb of contents, so you can run dense acids and concentrated solutions without overloading the wall. The 30.25 x 30.0 inch footprint and 37-inch height let it tuck under most batching and metering setups, and the cone outlet keeps sediment and slurry moving toward the drain instead of settling. Because this is a cone-bottom tank, plan a stand or structural support rated for the full 1,030 lb loaded weight at 1.9 SG to elevate the cone for discharge. Confirm your fitting and valve sizes by phone at 866-418-1777 before you plumb it. To match this 65-gallon body against your throughput, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide; for the geometry tradeoffs between 15, 30, and 45-degree cones, the cone bottom buyer's guide walks through how slope angle affects drainage.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity. The resin code reads HDLPE here, but before committing it to any chemical service, confirm whether your application calls for HDLPE versus a crosslinked (XLPE) wall, since the two resins resist different chemistries. Per the Snyder chemical-resistance chart, which is concentration- and temperature-specific, the following are listed as compatible at the noted concentrations, paired with the recommended fitting and gasket materials:
Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (under 16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM — concentration-sensitive, confirm by phone). Always verify against the OEM chart at your exact concentration and temperature, and browse the full Chemical Compatibility Database before ordering fittings. Need to hold something denser than 1.9 SG? This is Snyder's top SG rating in this 65-gallon cone body, so call 866-418-1777 and we will source a higher-rated tank.
The mistake to avoid
The single most common error on a chemical cone tank is matching the wrong gasket and fitting material to the chemistry. Several entries above call for Viton or Aflas gaskets and 316 stainless or CPVC fittings rather than the default EPDM and PVC — hydrochloric acid, hydrogen peroxide, sodium hypochlorite, and sulfuric acid among them. DEF is the quiet trap: buyers routinely default to PVC fittings, but the chart calls for 316 stainless at 32.5%, and the wrong metal contaminates the fluid. An EPDM gasket on a high-strength oxidizer or strong acid will fail even though the polyethylene wall holds. Spec the gasket and fitting to the chemical, not to whatever is in the parts bin.
