The Snyder Industries 3000 Gallon 30 Degree Plastic Cone Bottom Tank is a 1.9 specific-gravity-rated chemical workhorse molded from high-density linear polyethylene (HDLPE) in white, standing 120 inches tall on a 95 x 95-inch footprint. The 30-degree cone discharges settling slurries and dense chemistries far more aggressively than a shallower 15-degree cone, and the 1.9 SG rating means this Snyder cone tank carries heavy liquids that would overload a standard 1.5 SG-rated vessel. If you have been searching "3000 cone bottom tank" or "Snyder cone tank" for chemical duty, this is the heavy-rated option.
Will it work for your application
This 3000-gallon cone tank holds 25,020 lb full of water and is rated to carry up to 47,538 lb of contents at its 1.9 SG ceiling - that headroom is the whole reason for the heavier rating, but always size your cone stand and pad to the rated contents weight, not the water weight. A cone bottom must be fully supported in a matching steel or fiberglass cone stand; never set a cone tank on a flat pad. Factory fittings per the technical drawing include a FLANGE, an 18-inch PE threaded/vented fitting, and a MANWAY with 15-inch access for entry and cleanout. See the technical drawing on this page for the cone-apex outlet size and elevation - a 30-degree cone is self-draining only if the bottom fitting and downstream valve are sized for your slurry. Keep the 18-inch vented fitting clear in service: a sealed or blocked vent lets a transfer pump pull vacuum and collapse a poly cone tank, or lets fill pressure dome the top. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm the stand and footprint fit your space.
Chemical compatibility
This tank is molded in HDLPE and rated to 1.9 specific gravity, qualifying it for a wide range of dense industrial chemistries. Compatibility always depends on concentration, temperature, fitting material, and gasket material - confirm your exact service against the OEM chemical-resistance chart, which is concentration- and temperature-specific, and match fittings and gaskets to the chemical, not just to the tank. Chemistries suited to this HDLPE/1.9 SG cone tank include hydrochloric acid (37%, PVC fittings, Viton gaskets), sulfuric acid (98%, CPVC, Viton), phosphoric acid (85%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), acetic acid (60%, PP/PVC, EPDM), peracetic acid (30%, 316SS fittings, Aflas gaskets), hydrogen peroxide (50%, PVC, Viton), sodium hypochlorite (<16.5%, PVC, Viton), ferric chloride (50%, PVC, EPDM), ferric sulfate (60%, PVC, EPDM), ferrous sulfate (20%, PVC, EPDM), aluminum sulfate (50%, PVC, EPDM), polyaluminum chloride (PVC, EPDM), calcium chloride (40%, PVC, EPDM), magnesium chloride (30%, PVC, EPDM), sodium carbonate (30%, PVC, EPDM), potassium carbonate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium thiosulfate (40%, PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), ethylene glycol (100%, PVC, EPDM), propylene glycol (PP/316SS, EPDM), urea solution (50%, PP/PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM). Each linked chemical has its own page - start at our Chemical Compatibility Database, then drill into the specific chemistry, for example sulfuric acid, hydrochloric acid, sodium hypochlorite, peracetic acid, or DEF. At 1.9 SG this is already the heavy-duty rating for this geometry; if your chemistry exceeds 1.9 specific gravity, contact us before ordering, because a standard poly cone tank is not rated for it.
The mistake to avoid
The most common error on a cone tank like this is mismatching the fitting and gasket material to the chemical. The 1.9 SG HDLPE shell tolerates many aggressive liquids, but a PVC fitting on 98% sulfuric acid, or an EPDM gasket where Viton or Aflas is required, will fail long before the tank does. Watch the split: most salts and glycols run PVC fittings with EPDM gaskets, but oxidizers and strong acids need tougher wetted parts. Two cases burn buyers most - peracetic acid (30%) requires 316SS fittings with Aflas gaskets, the only such combination here, and DEF (32.5%) requires 316SS fittings because it corrodes ordinary steel and brass and is easily contaminated by the wrong metal. Match every wetted component, and verify your concentration against the OEM chart before ordering.
This Snyder cone tank ships LTL freight from the nearest stocking plant - Chowchilla, CA - quoted live to your ZIP code (it is a 3000-gallon cone tank, so plan for a cone stand and rigging at delivery).

For sizing, stand, and installation details, read the 3000 Gallon 30 Degree Cone Bottom Tank buyer's guide; a shallower 15-degree cone gives more usable volume in the same height but drains settling solids less aggressively, so see the 15-degree buyer's guide if your product does not settle.
