The Norwesco 3000 Gallon 15 Degree Cone Bottom Tank (SKU N-45141) is built for full-drain chemical and process service where you cannot leave product sitting in the bottom. The shallow 15-degree cone slopes contents toward a single outlet, and the white polyethylene body carries a 1.5 specific gravity rating - the number that decides which chemicals this tank can hold. It measures 120 inches tall on a 91 x 91 inch footprint, so confirm your pad and overhead clearance before ordering. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm this cone tank fits your batching or blending layout.
Will this Norwesco cone bottom tank work for your job
Filled with water this tank carries roughly 25,020 lb; at its maximum rated 1.5 specific gravity it is built to hold up to 37,530 lb of contents. That weight rides on a stand (sold separately for cone-bottom tanks), so your support structure and anchoring must be engineered for the loaded figure, not the empty shell. The 1.5 SG rating is the working ceiling: it covers water and a wide range of dilute chemicals, but heavier liquids push past what this wall thickness was designed to carry. The 15-degree cone is the shallowest of Norwesco's cone options - it lowers overall tank height and outlet height versus 30 and 45-degree cones, but drains more slowly and leaves slightly more heel, so choose a 30 or 45-degree cone if complete fast drain-down matters more than headroom. For full dimensional layout, including the outlet position at the cone apex, see the technical drawing on this page. The tank's installed fittings and outlet configuration are not specified in our records, so confirm bulkhead and outlet size and any pre-installed fittings by phone before ordering.
Chemical compatibility
This polyethylene tank is rated to 1.5 specific gravity. The resin grade shows as unconfirmed in our records, so confirm the exact resin (for example HDLPE vs XLPE cross-linked) before placing it in chemical service - different resins resist different chemistries. The chemicals below are compatible with a 1.5 SG polyethylene tank at the concentration shown; the listed fitting and gasket materials are the recommended wetted materials for that chemical, not parts that ship with the tank. Always verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Note your fitting and gasket materials before you order: DEF, for example, calls for 316 stainless fittings with EPDM gaskets, while most of the acids and salts above run on PVC and EPDM. Matching the gasket to the chemical prevents the slow leaks that ruin a chemical install.
Chemicals that need a higher-SG tank
Several common process chemicals are heavier than this 1.5 SG tank is rated for and require a 1.9 specific gravity tank instead - do not put them in this one. These include 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. Picking the SG rating to match your chemical - not just the gallon size - is the single most common and most expensive cone-tank mistake. Several of these also demand Viton or Aflas gaskets rather than EPDM, so check each chemical's page for the right gasket. We can supply the same 3000-gallon cone bottom in a 1.9 specific gravity build for these heavier chemistries - call 866-418-1777 to match the SG rating to your chemical. Verify every chemical against our Chemical Compatibility Database before you order.
