The 160 Gallon 45 Degree Cone Bottom Tank from Norwesco (SKU N-43845) holds 160 gallons in a steep 45-degree cone that drains thick or settling product completely, leaving no flat floor for sediment to stack on. It stands 52 inches tall on a 36-inch diameter footprint and is molded from polyethylene rated to 1.5 specific gravity, so it carries fluids up to 50 percent heavier than water without exceeding the wall's design limit. This is a cone bottom tank built for batching, mixing, and full-discharge transfer rather than passive storage.
Will this Norwesco cone tank handle your contents?
The 1.5 specific gravity rating is the number that decides this. Full of water the tank carries about 1,334 pounds, and at the full 1.5 SG rating it is engineered for up to roughly 2,002 pounds of contents. Size your stand or pad to that 2,002-pound figure, not the water weight, because a 45-degree cone must be elevated on a skirt or stand to clear the outlet for gravity discharge. Before you commit a product, confirm its specific gravity falls at or under 1.5 at your operating temperature. Review the technical drawing on this page for exact fitting locations and outlet position, and use the Tank Sizing Calculator and Tank Sizing Guide to match the 160-gallon working volume to your batch size.
Chemical compatibility
This tank is polyethylene with a 1.5 specific gravity rating. The resin code on file is not confirmed, so confirm the exact resin with us before placing it in chemical service, since cross-linked and linear polyethylene differ in resistance. At the 1.5 SG rating, this cone tank suits the following chemicals when paired with the matching fittings and gaskets: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets, details), Aluminum Sulfate at 50% (PVC, EPDM, details), Calcium Chloride at 40% (PVC, EPDM, details), Ferrous Sulfate at 20% (PVC, EPDM, details), Magnesium Chloride at 30% (PVC, EPDM, details), Sodium Carbonate at 30% (PVC, EPDM, details), Urea Solution at 50% (PP/PVC, EPDM, details), and Ozonated Water up to 10 PPM (PVC, EPDM). One outlier worth flagging: DEF at 32.5% is compatible at 1.5 SG but calls for 316SS fittings with EPDM gaskets (details), not the PVC the others use, so a DEF buyer should spec stainless rather than defaulting to PVC. All compatibility is concentration- and temperature-specific, so verify your exact concentration and operating temperature against the per-chemical page and the Chemical Compatibility Database.
What needs a higher-SG tank instead
Several common process chemicals exceed what a 1.5 SG tank should hold and require a 1.9 specific gravity tank: 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. If your application uses any of these, do not order this tank for that service. The gasket and fitting spec also tightens: Hydrochloric Acid, Phosphoric Acid, Hydrogen Peroxide, and Sodium Hypochlorite call for PVC fittings with Viton gaskets; Hydrofluoric and Hydrofluosilicic Acid call for PP/PVC fittings with Viton; Sulfuric Acid calls for CPVC fittings with Viton; and Peracetic Acid calls for 316SS fittings with Aflas gaskets rather than standard EPDM. Check the per-chemical page in the Chemical Compatibility Database for the required SG, fitting, and gasket spec, and call 866-418-1777 for the 1.9 SG version of this cone tank before buying.
Freight and ordering
This cone bottom tank ships LTL freight from the Norwesco plant in Sheldon, Iowa, with the cost quoted live to your ZIP code through our Freight Cost Estimator. The most common mistake on a 45-degree cone tank is ordering it for a chemical that needs the 1.9 SG version, or pairing it with the wrong gasket or fitting material, so settle your chemical, concentration, and SG first. For a deeper walkthrough see our 160 Gallon 45 Degree Cone Bottom Tank buyer's guide and the Norwesco cone angle selection guide. Questions on fit or freight, call 866-418-1777.
