The 5500 Gallon 30 Degree Plastic Cone Bottom Tank from Snyder Industries is a 5,500-gallon white polyethylene cone bottom tank rated to a 1.5 specific gravity, standing 240.5 inches tall on a 90 x 90 inch footprint. The 30-degree cone geometry drains contents toward a single low point, which is why these tanks are used for batching, mixing, and full-discharge chemical handling where settled solids or complete drain-down matter. This page answers the three things that decide a cone-bottom purchase: whether the tank handles your contents, what shipping looks like, and the one mistake that sends the wrong tank to your site.
Will it handle your contents?
Capacity and weight govern the cone bottom decision. Filled with water this tank carries roughly 45,870 lb, and at its full 1.5 specific gravity rating it is engineered for contents up to about 68,805 lb. Use those numbers when you size the stand, ring wall, or structural steel beneath it, since a cone bottom tank transfers all of that load through its support legs or skirt rather than across a flat pad. Size your secondary containment to the 90 x 90 in footprint plus freeboard, which chem service almost always requires. Match the contents to the 1.5 SG rating: any liquid heavier than that exceeds what this wall thickness was built to hold long-term. The white color lets you read liquid level through the wall in good light. For help confirming the working volume you actually need, the Tank Sizing Calculator and Tank Sizing Guide walk through it, and the 5500 Gallon 30 Degree Cone Bottom Tank buyer's guide covers this size specifically.
Chemical compatibility
This is a polyethylene tank rated to a 1.5 specific gravity. The source data lists the resin as HDLPE but carries a question mark on that designation, so confirm whether this is HDLPE or XLPE with us before committing it to chemical service. At the 1.5 SG rating, this tank is suited to chemicals such as Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), DEF (32.5%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Sodium Carbonate (30%), Urea Solution (50%), and ozonated water (up to 10 PPM), when fitted appropriately. Acetic Acid and Urea Solution accept PP or PVC fittings; Aluminum Sulfate, Calcium Chloride, Ferrous Sulfate, Magnesium Chloride, and Sodium Carbonate use PVC; DEF specifically calls for 316 stainless. All of these services run EPDM gaskets. Verify your exact concentration and temperature against the OEM chemical-resistance chart before ordering, since both numbers move the rating.
Some chemicals need a higher 1.9 SG tank instead of this 1.5 SG model. If you are storing 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, or Zinc Orthophosphate, step up to the 1.9 SG version rather than running this tank past its rating. Gasket material matters on that list: Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, Sulfuric, and Sodium Hypochlorite require Viton; Peracetic Acid requires Aflas; the rest run EPDM. Full per-chemical detail lives in our Chemical Compatibility Database.
Freight and ordering
This Snyder cone bottom tank ships by LTL freight from the Lincoln, Nebraska plant, quoted live to your ZIP. Because of its 240.5-inch height it moves as a tall freight load, so confirm overhead clearance and an offload plan before delivery. The fitting package on a cone bottom tank this size is configured to order, so confirm bulkhead, outlet, and vent placement with us rather than assuming a factory layout. Get a freight estimate to your ZIP through the Freight Cost Estimator, see the technical drawing on this page for dimensions and fitting locations, or call 866-418-1777 to confirm the right specific gravity rating, fittings, and freight for your application.
