300 Gallon 30 Degree Cone Bottom Tank with Poly Stand

The Norwesco 300 Gallon 30 Degree Cone Bottom Tank (SKU N-62343) is built for processes that need to drain completely - the 30-degree cone bottom and matching black poly stand let solids and liquid empty out through the 2" outlet instead of settling on a flat floor.It holds 300 gallons in a 49" diameter footprint, stands 61" tall on its stand, and ships empty at 159 lbs.The tank is molded from white polyethylene, carries a 1.5 specific gravity rating, has a 16" lid for filling and access, and is rated to a maximum contents temperature of 120 F (48 C).Norwesco lists this tank as FDA Approved.

Will it work for your process?

Match the tank to what you are storing by weight, not just gallons.Filled with water this Norwesco tank carries about 2,502 lbs of contents; at its full 1.5 specific gravity rating it is built to hold up to 3,753 lbs.Because the cone hangs below the stand, plan your discharge plumbing and any containment around the 61" overall height and the 49"-diameter footprint.Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the fill weight your stand pad and floor need to support before you order.

Chemical compatibility

This is a polyethylene tank with a 1.5 specific gravity rating, molded to the Snyder Industries OEM chemical resistance chart.The resin is listed as HDLPE with a question mark - confirm HDLPE versus XLPE (cross-linked) for your exact chemical before you put it into service, since the two behave differently with some fluids.Compatibility is always concentration- and temperature-specific, so verify your exact chemical, concentration, temperature, and your fitting and gasket materials against the OEM chart.

Within its 1.5 SG rating, this tank suits these chemicals (concentrations and recommended fitting/gasket materials from the chart): Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets); Aluminum Sulfate at 50% (PVC, EPDM); Calcium Chloride at 40% (PVC, EPDM); DEF at 32.5% (note 316SS fittings, not the PVC used by its neighbors here, with EPDM); Ferrous Sulfate at 20% (PVC, EPDM); Magnesium Chloride at 30% (PVC, EPDM); Sodium Carbonate at 30% (PVC, EPDM); Urea Solution at 50% (PP/PVC, EPDM); and Ozonated Water up to 10 PPM (PVC, EPDM).DEF and urea solution need only a 1.5 SG tank, so this 1.5-rated tank covers them with margin - but DEF still calls for 316SS fittings, so don't carry over a PVC fitting spec from the chemicals beside it.

A number of heavier chemicals require a higher 1.5 SG tank, not this one, and their seal specs are not uniform: some seat on EPDM (Ethylene Glycol at 100%, Ferric Chloride at 50%, Potassium Hydroxide saturated), several need Viton (Hydrochloric Acid at 37%, Sodium Hypochlorite under 16.5%, Hydrogen Peroxide at 50%, Phosphoric Acid at 85%, Sulfuric Acid at 98%), and Peracetic Acid at 30% goes further still with 316SS fittings and Aflas gaskets.If your process involves those, step up to the heavier-rated tank rather than forcing this rating.Check any chemical against our Chemical Compatibility Database first.

The mistake to avoid

The costly error on a cone-bottom chemical tank is buying to gallons and specific gravity alone while ignoring the fitting and gasket callouts.The same fluid that is fine against one material may need another entirely - 98% Sulfuric Acid, for instance, calls for CPVC fittings and Viton gaskets, not the plain PVC/EPDM combination the milder salts use, and Peracetic Acid steps up to 316SS with Aflas seals.Spec the outlet and gasket materials from the chart for your exact fluid, and confirm the HDLPE-versus-XLPE resin question before service.See the technical drawing on this page for dimensions and outlet placement.
