Enduraplas 1550 Gallon Black Cone Bottom Tank with Stand

The Enduraplas 1550 Gallon Black Cone Bottom Tank with Stand (SKU THC01550KB) is a full-drain vessel for batching, mixing, and dosing where the tank has to empty completely between runs. It stands 95" tall on an 85"-diameter footprint, molded in black polyethylene with a 1.9 specific gravity rating, and ships empty at roughly 300 lb. A 16" threaded vented manway sits up top for filling and inspection, and a 3" PP female NPT bulkhead fitting drains the cone. The tank is FDA approved. Because a cone bottom has no free-standing base, this package includes the matching stand that carries the loaded weight and holds the outlet at working height.

Will it work for your process?

Size to the load, not the label. Filled with water this 1550 gallon tank carries about 12,927 lb; at its full 1.9 SG rating it can hold up to roughly 24,561 lb of contents. That 24,561 lb ceiling assumes SG 1.9 — most fluids weigh less, so compute the real design load at the specific gravity of your actual fluid and confirm the stand and slab are rated for that figure before you fill. Our Tank Sizing Calculator and Tank Sizing Guide walk the weight math, and the stand selection decision tree plus the Norwesco, Snyder, and Enduraplas compatibility matrix help you match frame to tank. See the technical drawing on this page for manway, outlet, and stand geometry.

Chemical compatibility

This is a polyethylene tank rated to 1.9 SG. Its resin is recorded as HDLPE but flagged for confirmation, so verify HDLPE versus XLPE with us before committing it to chemical service — the compatibility below is indicative, not a guarantee. It is drawn from the Snyder Industries OEM chemical resistance chart, which is concentration- and temperature-specific, and it is being applied here to an Enduraplas tank, so confirm your exact chemical, concentration, temperature, and fitting and gasket materials before ordering.

Chemistries the 1.9 SG tank supports (with the fitting and gasket the chart calls for) include ethylene glycol at 100% (PVC / EPDM), ferric chloride at 50% (PVC / EPDM), ferric sulfate at 60% (PVC / EPDM), hydrochloric acid at 37% (PVC / Viton), hydrofluoric acid at 48% (PP or PVC / Viton), hydrofluosilicic acid at 26% (PP or PVC / Viton), hydrogen peroxide at 50% (PVC / Viton), peracetic acid at 30% (316SS / Aflas), phosphoric acid at 85% (PVC / Viton), polyaluminum chloride (PVC / EPDM), potassium carbonate at 50% (PVC / EPDM), saturated potassium hydroxide (PVC / EPDM), propylene glycol (PP or 316SS / EPDM), sodium bisulfate (PVC or PP / EPDM), sodium bisulfite (PVC or PP / EPDM), sodium hypochlorite under 16.5% (PVC / Viton), sodium thiosulfate at 40% (PVC / EPDM), sulfuric acid at 98% (CPVC / Viton), and zinc orthophosphate (PP or 316SS / EPDM). Lower-density chemistries such as acetic acid at 60%, aluminum sulfate at 50%, calcium chloride at 40%, urea solution at 50%, ferrous sulfate at 20%, magnesium chloride at 30%, sodium carbonate at 30%, and ozonated water up to 10 PPM run within this tank's rating.

Match wetted parts to the chart, not to the stock hardware. The included 3" outlet is PP, which suits glycols, urea, and similar mild service — but DEF at 32.5% calls for 316SS wetted parts (EPDM gasket), and acids and oxidizers such as sulfuric at 98% (CPVC), hydrochloric, hydrogen peroxide, and sodium hypochlorite need PVC or CPVC with Viton, while peracetic acid and zinc orthophosphate need 316SS or Aflas. Tell us the chemistry and we'll spec the bulkhead and gasket to match before it ships. Cross-check your fluid in our Chemical Compatibility Database.

Freight and ordering

This 1550 gallon Enduraplas black cone bottom tank with stand ships LTL freight from our Neche, North Dakota plant, quoted live to your ZIP through the Freight Cost Estimator or by phone at 866-418-1777. It's a tall, palletized cone-and-stand assembly, so confirm forklift or loading-dock access for delivery. Call with your chemical, concentration, and temperature and we'll confirm the resin, outlet, and gasket build before it leaves North Dakota.
