The Norwesco 1600 Gallon 30 Degree Cone Bottom Tank with Poly Stand is a closed-top HDPE cone tank built for chemical batching, mixing, and full-drain dispensing where you need every gallon to gravity-feed toward a single point. It is molded to a 1.9 specific gravity rating, rated to 120 F / 48 C, and carries a 2" outlet at the cone tip with a 16" lid up top. Empty it weighs 558 lb, and the 30-degree cone drops into a matched poly stand so the discharge clears pumps, valves, and totes below.
Will it work for your process
Capacity is 1600 gallons in an 89" diameter footprint standing 96" tall on its stand. The 1.9 SG rating is the number that matters for chemical duty: it means the wall is engineered to hold liquids up to 1.9 times the weight of water. Filled with water this tank carries roughly 13,344 lb; at its maximum rated contents weight it is built for about 25,354 lb of liquid load. Run your batch volume and drain-down schedule through the Tank Sizing Calculator and the Tank Sizing Guide so the cone angle and 2" outlet match your flow rate. The resin is FDA Approved. Confirm the 2" outlet and 16" lid suit your fill-and-discharge hardware; the technical drawing on this page shows the exact port locations.
Chemical compatibility
This tank uses a polyethylene resin rated to 1.9 specific gravity. The resin code on file ends in a question mark, so confirm whether your unit is HDLPE or XLPE before chemical service, since crosslinked and linear polyethylene resist different chemistries. Compatibility below comes from the Snyder Industries OEM chemical resistance chart and is concentration- AND temperature-specific, capped at this tank's 120 F / 48 C ceiling. Concentrated acids such as sulfuric (98%) and hydrochloric (37%) generate real exotherm as they mix, so keep the batch under that 120 F limit and verify your exact chemical, concentration, temperature, and fitting plus gasket materials before ordering. Every chemical the chart supports here sits at or below a 1.9 required SG, so this 1.9-rated wall covers the full list with no heavier tank required.
At 1.9 SG the chart supports ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), hydrochloric acid (37%, Viton), hydrofluoric acid (48%, Viton), hydrofluosilicic acid (26%, Viton), hydrogen peroxide (50%, Viton), phosphoric acid (85%, Viton), sodium hypochlorite (under 16.5%, Viton), sulfuric acid (98%, CPVC and Viton), peracetic acid (30%, 316SS and Aflas), plus neutral salts and bases including potassium carbonate, potassium hydroxide, sodium thiosulfate, sodium bisulfate, sodium bisulfite, polyaluminum chloride, propylene glycol, and zinc orthophosphate. Lower-SG services all within this wall include DEF (32.5%), urea solution (50%), acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), magnesium chloride (30%), ferrous sulfate (20%), sodium carbonate (30%), and ozonated water (up to 10 PPM). Match fitting material and gasket to the specific chemical, and check the full Chemical Compatibility Database first.
The mistake to avoid
The single most common error on a cone-bottom chemical tank is trusting a generic "polyethylene is fine" answer. Two things sink that: the resin question (HDLPE vs XLPE) and the fitting/gasket mismatch. The acids above demand Viton or CPVC hardware, not the EPDM that ships on water tanks. Just as important, DEF and peracetic acid need 316SS metallic fittings, and urea, propylene glycol, and zinc orthophosphate call for PP or 316SS rather than the PVC that suits the acids. Verify resin, concentration, temperature, and hardware together before you fill.
This tank ships LTL freight from the nearest Norwesco plant to you, out of Hanford, CA, Lancaster, OH, or Tooele, UT, with freight quoted live to your ZIP through the Freight Cost Estimator. For chemical service, confirm the exact resin (HDLPE vs XLPE) with us before ordering, since both the 1.9 SG rating and the crosslink-versus-linear distinction hinge on it.
