The 5500 Gallon 30 Degree Plastic Cone Bottom Tank from Snyder Industries is a 5,500-gallon white polyethylene cone-bottom tank built for chemical service, with a 1.9 specific gravity rating that lets it hold dense, full-strength chemistries most water-rated tanks cannot. It stands 241 inches tall on a 90 x 90 inch footprint and requires a properly engineered steel support stand sized to its 30-degree cone. Below it answers the three questions every buyer asks: will it hold my chemical, how does it ship, and what mistake do I need to avoid.
Will it work for your application
This is a cone bottom tank engineered for complete drainage - the 30-degree cone discharges contents to the outlet without the residual heel a flat-bottom tank leaves behind, which matters for batching, settling, and full chemical changeouts. The 1.9 specific gravity rating is the number to anchor on: the wall is built to safely carry liquids up to 1.9 times the weight of water, and at this size that is already Snyder's heaviest-duty wall rating - there is no higher-SG cone-bottom version to step up to because none is required, even for the densest listed chemistries like sulfuric acid at 98% or ferric chloride at 50%. Run the weights through the on-page sizing data and the Tank Sizing Calculator before you buy: full of water (SG 1.0) the contents weigh about 45,870 lb, and at the full 1.9 SG rating the contents can reach roughly 87,153 lb. Those numbers drive your stand design, anchoring, and pad. Use the Tank Sizing Guide if you are still confirming capacity against your process volume.
Chemical compatibility
This Snyder tank is molded from polyethylene. Confirm the resin grade (HDLPE vs crosslinked XLPE) with us before committing to strong oxidizers like sodium hypochlorite or hydrogen peroxide, because the crosslinked grade changes oxidizer resistance. At its 1.9 SG rating it is compatible with the following chemistries at the concentrations, fitting materials, and gasket materials shown - always cross-check 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
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (Saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Match the fitting and gasket material exactly to your chemical - the same tank takes EPDM seals for most salts and glycols, Viton or Aflas for strong acids and oxidizers, and 316SS or CPVC fittings where the chemistry demands it. Browse the full Chemical Compatibility Database for any chemistry not listed above.
The mistake to avoid: it ships as a bare vessel
This tank ships as a bare vessel - bulkhead fittings, gaskets, and the cone outlet hardware are specified separately, not included in the box. The most common mistake is ordering the tank without matching the fitting and gasket materials to your chemical from the table above, then discovering the seals are wrong for the service. Spec those materials up front and call 866-418-1777 if you want us to work the fitting package with you.
Freight and how it ships
This tank ships LTL freight from the Snyder Industries plant in Lincoln, NE, quoted live to your ZIP. At 241 inches tall it is an oversize shipment - confirm you have the equipment and clearance to receive and offload it. Get a real number before you order with the Freight Cost Estimator, or call us at 866-418-1777 and we will work the freight to your delivery point. For a deeper walkthrough of cone-bottom sizing and stand selection, see the 5500 Gallon 30 Degree Cone Bottom Tank buyer's guide and the cone-angle selection guide: 15 vs 30 vs 45 degrees.
