The Norwesco 1600 Gallon Light Blue Heavy Duty Cone Bottom Tank is built for full drain-down chemical service: a 1.9 specific-gravity rating, a cone bottom that empties by gravity, and 84 inches of height over an 88 x 88 inch footprint. The light blue tint lets you read the level at a glance while shading contents from direct light. If you are weighing cone angles or cradle setups, the Norwesco cone bottom tank buyer's guide and the 1600 gallon 30-degree complete buyer's guide walk through the trade-offs.
Will it work for your application?
This is a heavy-duty cone bottom rated for fluids up to a 1.9 specific gravity (about 15.85 lb/gal) — check your chemical's SG against that ceiling before you order. Filled with water (SG 1.0) it carries about 13,344 lb; at its maximum rated contents it holds roughly 25,354 lb. That spread is the number that matters: a 1600-gallon batch of a 1.6 SG fertilizer or a concentrated acid weighs far more than the same volume of water, and the cone, the stand, and your foundation all have to carry it. Because a cone bottom drains entirely to the centered outlet, it needs a matching stand or cradle — see the cone bottom tank stand compatibility matrix for Norwesco-rated supports, or pair it with the poly-stand setup covered in the poly-stand buyer's guide. Run your fill weight and headroom through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a footprint.
Chemical compatibility
This tank is molded polyethylene with a 1.9 specific-gravity rating. The resin is listed as HDLPE pending confirmation, so confirm HDLPE versus XLPE with us before putting it into chemical service — crosslinked polyethylene generally carries broader chemical resistance than linear, so settling the resin question protects both your warranty and your compatibility assumptions. Compatibility below is concentration- and temperature-specific; always match your exact concentration and operating temperature.
Within its 1.9 SG rating, this tank is listed compatible with chemicals including Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), DEF (32.5%), Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Hydrochloric Acid (37%), Hydrofluoric Acid (48%), Hydrofluosilicic Acid (26%), Hydrogen Peroxide (50%), Magnesium Chloride (30%), Peracetic Acid (30%), Phosphoric Acid (85%), Polyaluminum Chloride, Potassium Carbonate (50%), Potassium Hydroxide (saturated), Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Carbonate (30%), Sodium Hypochlorite (under 16.5%), Sodium Thiosulfate (40%), Sulfuric Acid (98%), Urea Solution (50%), Zinc Orthophosphate, and Ozonated Water (up to 10 PPM). Fitting and gasket materials are chemical-specific and not interchangeable: the most aggressive listed services — Sulfuric Acid (98%), Sodium Hypochlorite, Hydrochloric Acid (37%), Hydrofluoric Acid (48%), Phosphoric Acid (85%), and Hydrogen Peroxide (50%) — all require Viton gaskets, and sulfuric uniquely calls for CPVC fittings, so a stock PVC outlet kit is not adequate for it. DEF and zinc orthophosphate use 316 stainless fittings; peracetic acid needs 316SS fittings with an Aflas gasket; most of the balance run PVC or PP fittings with EPDM gaskets. Verify every fitting and gasket against your chemical on the Chemical Compatibility Database.
The mistake to avoid
The single most common error on a cone bottom this size is treating the SG rating as a license to store anything. The 1.9 rating sets the heaviest fluid the wall and cone are built to carry, not a compatibility guarantee — a chemical can be chemically aggressive even when it is light. Confirm both the specific gravity of your fluid and its resin compatibility, and resolve the HDLPE-versus-XLPE question before you fill. Then match the fitting and gasket materials exactly to the chemical, because the wrong elastomer at an outlet fails long before the tank wall does — reusing a plain PVC kit on sulfuric acid is the textbook version of this failure.
This tank ships LTL freight from the nearest Norwesco plant in our network — Hanford, CA; Lancaster, OH; or Tooele, UT. Because it is molded at three coast-spread plants, your LTL rate keys off whichever is closest to you, with the carrier quoted live to your ZIP. Get your number on the Freight Cost Estimator, see the technical drawing on this page for the outlet and fitting layout, and call 866-418-1777 to confirm resin and fittings for your service.
