The Snyder Industries 5500 Gallon Black Cone Bottom Tank is a 1.5 specific-gravity vessel built for full-drain chemical batching, mixing, and dosing where you need the cone to empty completely. Molded in black polyethylene by Snyder Industries, it stands 241 inches tall on a 90.0 x 90.0 inch footprint and holds a nominal 5,500 gallons. Filled with plain water it carries about 45,870 pounds; at its maximum rated specific gravity of 1.5 the contents alone can reach 68,805 pounds. That 68,805 lb figure, not the water weight, is the number your stand and foundation must be engineered to support. This is a cone bottom tank that requires a matching stand to hold the cone off the ground at working height.
Will it work for your application?
The deciding number on any cone bottom tank is specific gravity. This tank is rated to 1.5 SG, meaning it is built to hold liquids up to 1.5 times the density of water. Before you commit, confirm your chemical's specific gravity at its working concentration and temperature against that 1.5 rating. One detail buyers overlook: the fitting and outlet configuration is not specified in this listing, so the bottom outlet, valve, and bulkhead fittings must be confirmed and specified at order rather than assumed to ship installed. This matters because every compatible chemical below names a required fitting material and gasket you need to order to match. Run your fill volume through the Tank Sizing Calculator and review the Tank Sizing Guide if you are deciding between this 5500 and an adjacent size; the 5500 Gallon 30 Degree Cone Bottom Tank buyer's guide walks the size decision, and the cone bottom tank stand compatibility matrix is how you pick a stand rated for the full 68,805 lb loaded weight, not a generic stand.
Chemical compatibility
This tank is molded from polyethylene rated at 1.5 specific gravity. The resin grade is not confirmed in our data, so before placing any chemical in service confirm the exact resin (for example HDLPE versus XLPE cross-linked polyethylene) with the manufacturer, since different resins resist different chemistries. At the 1.5 SG rating, this tank suits the following at the listed concentrations, paired with the indicated fitting and gasket materials: Acetic Acid 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate 50% (PVC, EPDM), Calcium Chloride 40% (PVC, EPDM), Ferrous Sulfate 20% (PVC, EPDM), Magnesium Chloride 30% (PVC, EPDM), Sodium Carbonate 30% (PVC, EPDM), Urea Solution 50% (PP/PVC, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Diesel exhaust fluid (DEF) at 32.5% is also a fit here, but note it is the one chemical on this list that calls for 316 stainless steel fittings with EPDM gaskets rather than PVC, so do not default to PVC for a DEF build. Always verify against the OEM chemical-resistance chart at your exact concentration and temperature before service, and see the acetic acid, aluminum sulfate, calcium chloride, DEF, ferrous sulfate, magnesium chloride, sodium carbonate, and urea solution pages in our Chemical Compatibility Database for detail.
Chemicals that need a higher-SG tank
Several common chemicals exceed what a 1.5 SG tank should hold and require a 1.9 specific-gravity tank instead. If you are storing any of these, do not use this 1.5 tank: 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. Sodium hypochlorite in particular is a frequent mistake on cone bottom tanks: it pushes past the 1.5 rating and wants PVC fittings with Viton gaskets, not EPDM. Several of these acids also call for Viton or Aflas gaskets rather than EPDM, so match the fitting and gasket material to the chemical. If your chemistry lands on this list, do not settle for the 1.5 tank: call 866-418-1777 or request a quote and we will spec the 1.9 SG version of this 5500 gallon cone bottom tank for you.
