The Snyder Industries 3000 Gallon XLPE Cone Bottom Tank (SKU 8360000N46) is a 3,000-gallon black crosslinked linear polyethylene (XLPE) cone bottom tank built for chemical service, rated to a specific gravity of 1.5. It stands 120 inches tall on a 95 x 95 inch footprint, and its full cone-bottom geometry drains completely - the reason process and dosing operators reach for a cone tank over a flat-bottom vertical. As a Snyder XLPE cone bottom tank, it carries a heavier resin wall than a standard water-grade tank, which is what lets it hold heavier-than-water solutions up to 1.5 SG.
Will it work for your application?
Filled with plain water this tank carries about 25,020 lb; at its full 1.5 SG rating the contents can reach roughly 37,530 lb, so size the stand and pad for the rated chemical load, not the water figure. Run those numbers against your fill medium with the Tank Sizing Calculator and the Tank Sizing Guide before you set it. Per the technical drawing on this page, the tank carries a flange, an 18" polyethylene threaded/vented fitting, and a 15-inch manway for inspection and cleaning access. A cone bottom tank must sit in a matching cone-bottom stand - it cannot stand on its own - so confirm stand fit using the Cone Bottom Tank Stand Compatibility Matrix. For broader sizing context on this capacity, see the 3000 Gallon 15 Degree Cone Bottom Tank buyer's guide and the 30 degree cone bottom guide. If you also need engineered secondary containment, the Snyder Captor Plus 110% containment vs UL-142 comparison walks through SPCC-driven options.
Chemical compatibility
This is an XLPE tank rated to 1.5 specific gravity. Match the chemical, its concentration, and the fitting and gasket materials to your exact service before filling. The chemicals below are compatible with a 1.5 SG XLPE tank at the listed concentrations, paired with the noted fitting and gasket materials - always confirm 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 the DEF and urea-solution entries: this tank is a clean fit for diesel exhaust fluid and urea dosing service when plumbed with the right materials. Some heavier solutions need a higher-SG (1.9) tank than this 1.5-rated body - if you are storing Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrofluosilicic Acid (Viton gaskets), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol (PP/316SS fittings), or Sodium Thiosulfate, step up to the 1.9 SG version rather than this one. Cross-check every chemical against our Chemical Compatibility Database first.
The mistake to avoid
The most common error on a cone bottom chemical tank is matching the resin and SG but ignoring the fittings. An XLPE wall rated to 1.5 SG handles the chemical, but a PVC fitting on a service that calls for PP, 316SS, or Viton becomes the leak point. Match the fitting and gasket material in the list above to your exact chemical and concentration, and verify the stand is rated for the 37,530 lb full chemical load - not the 25,020 lb water weight.
