The Norwesco 10,000 Gallon 30 Degree Cone Bottom Tank (SKU N-44984) is a closed-top bulk vessel molded from high density linear polyethylene in black, carrying a 1.9 specific gravity rating - the heavy-duty resin rating that makes it suitable for dense process chemicals, not just water. The 30-degree cone drains to its apex for complete discharge, which is why operators reaching for a cone bottom tank, cone tank, or HDPE cone-bottom for full-drainage service land on this SKU. It stands 190 inches tall on a 141 x 141 inch footprint - and that 190 in overall height includes the cone, so usable straight-wall volume is less than a flat-bottom of the same shell. Plan your stand height, ceiling clearance, and slab before ordering.
Will it work for your application?
This is a tank-only vessel, so you select the stand and the wetted-component package to match your service - no fittings or bulkhead penetrations are pre-installed, and fitting locations are buyer-specified. The 1.9 SG rating means the wall is built to hold contents up to 1.9 times the weight of water. Filled with water this tank carries about 83,400 lb; loaded to its maximum rated contents weight it carries up to 158,460 lb - those numbers drive your stand selection, anchoring, and foundation. Because a 30-degree cone needs elevation to discharge and to clear an outlet valve, the apex angle sets the minimum stand height for full drainage; pair the tank with a rated stand. Our Cone Bottom Tank Stand Compatibility Matrix covers Norwesco, Snyder, and Enduraplas stand fitment, the Norwesco Cone Bottom Tank Buyer's Guide explains 15 vs 30 vs 45 degree selection, and the Tank Sizing Calculator and Tank Sizing Guide help confirm usable capacity against your batch volume. See the technical drawing on this page for dimensional detail.
Chemical compatibility
This vessel is high density linear polyethylene (HDLPE) at a 1.9 SG rating. Confirm HDLPE versus XLPE before committing the tank to chemical service - the two resins behave differently with certain media. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific; verify your exact concentration and operating temperature before finalizing. The fitting and gasket materials listed are the recommended wetted-component pairings, since the tank shell, the fittings, and the gaskets must each be rated for the chemical.
Compatible media for this HDLPE 1.9 SG tank include acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, 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). Note the wetted-material shifts: sodium hypochlorite, hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, and sulfuric acid call for Viton gaskets, peracetic acid calls for Aflas, and sulfuric acid calls for CPVC fittings rather than standard PVC.

The mistake to avoid
The costly error on a tank this large is matching the gasket to the fitting instead of to the chemical. A black HDLPE shell at 1.9 SG handles the media above, but EPDM gaskets will fail fast on oxidizers like sodium hypochlorite and hydrogen peroxide and on strong acids - those need Viton, and peracetic acid needs Aflas. Keep load rating and chemical rating separate in your head: the 1.9 SG figure covers the weight the wall can hold, not the service-life timeline against an oxidizer. HDLPE is rated for sodium hypochlorite, hydrogen peroxide, and peracetic acid, but it ages faster against those than against inert media, so confirm expected service life, not just compatibility. The second mistake is treating the tank rating as the whole system: this is tank-only, so the stand, fittings, and gaskets each have to be independently rated for both the chemical and the loaded weight up to 158,460 lb. When in doubt on top-fitting layout, our tank-top fitting placement guide walks through vent, fill, level, and drain layout that avoids cross-contamination.
