Enduraplas 1550 Gallon Green Cone Bottom Tank with Stand

The Enduraplas 1550 Gallon Green Cone Bottom Tank with Stand (SKU THC01550KG) is built for full-drain chemical batching, mixing, and storage where you need to empty the vessel completely between runs.The green polyethylene tank rides in its own stand, stands 95" tall on an 85"-diameter footprint, and carries a 1.9 specific gravity rating, an empty weight of 300 lb, and an FDA-approved resin.It ships with a 3" PP female NPT bulkhead outlet at the cone tip and a 16" threaded vented manway up top, so you can gravity-drain, feed a transfer pump, and vent the headspace on a single 1550 gallon tank.

Will it work for your process?

Size the tank by weight, not just gallons.Filled with water this vessel loads roughly 12,927 lb, and at its 1.9 SG rating it can carry up to about 24,561 lb of contents.That number drives your stand rating, pad, and anchoring decisions long before the tank arrives.The 1.9 SG rating is the key spec for chemical duty here: it tells you how dense a liquid the wall thickness is engineered to hold, and it happens to be the top of the chart, so this Enduraplas cone bottom tank covers the full density range.Run the numbers against your actual fluid with the Tank Sizing Calculator and the Tank Sizing Guide before you commit.Because this is a cone-bottom tank on a stand, stand selection matters as much as the tank itself - see the steel-frame vs poly stand decision tree and the Norwesco, Snyder, and Enduraplas stand compatibility matrix.The tank and stand ship as the pair named above - the one 3" bulkhead and the 16" manway - not as a fittings package, so plan any additional penetrations into your install.

Chemical compatibility

This tank is rated to 1.9 specific gravity.The resin is listed as HDLPE but not fully confirmed - confirm HDLPE vs XLPE with us before putting it into chemical service, because the crosslink type changes what it will hold.Compatibility below is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific; always verify your exact chemical, concentration, temperature, and the fitting and gasket materials before ordering.Because this tank carries the full 1.9 SG rating, it is actually over-specified for lighter fluids - DEF at 32.5% and Urea Solution at 50% only require a 1.9 SG tank, so you have real wall-thickness headroom for those duties (both still want a 316SS-wetted outlet, not the stock PP).Verified-compatible fluids and their recommended fitting/gasket pairings include: Acetic Acid 60% (PP/PVC, EPDM), Aluminum Sulfate 50% (PVC, EPDM), Calcium Chloride 40% (PVC, EPDM), DEF 32.5% (316SS, EPDM), Ethylene Glycol 100% (PVC, EPDM), Ferric Chloride 50% (PVC, EPDM), Ferric Sulfate 60% (PVC, EPDM), Ferrous Sulfate 20% (PVC, EPDM), Hydrochloric Acid 37% (PVC, Viton), Hydrofluoric Acid 48% (PP/PVC, Viton), Hydrofluosilicic Acid 26% (PP/PVC, Viton), Hydrogen Peroxide 50% (PVC, Viton), Magnesium Chloride 30% (PVC, EPDM), Peracetic Acid 30% (316SS, Aflas), Phosphoric Acid 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate 30% (PVC, EPDM), Sodium Hypochlorite under 16.5% (PVC, Viton), Sodium Thiosulfate 40% (PVC, EPDM), Sulfuric Acid 98% (CPVC, Viton), Urea Solution 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM).Match the gasket to the fluid - Viton and Aflas for the aggressive oxidizers and acids, EPDM for the salts and glycols.Full detail lives in our Chemical Compatibility Database.

The mistake to avoid

The single biggest error on a cone-bottom chemical tank is matching the fitting and gasket to the tank instead of to the chemical.The stock 3" PP bulkhead is the general-purpose baseline, but several fluids on the chart above force a specific upgrade off that baseline - CPVC for 98% sulfuric acid, 316 stainless for DEF and peracetic acid, and Viton or Aflas gaskets for the oxidizers like hypochlorite and hydrogen peroxide.Putting an EPDM gasket in front of concentrated sulfuric or hypochlorite is how a new tank leaks in a week.Confirm the outlet material and gasket for your exact chemical before it ships.And don't seal the vented manway: it does real work here, because a draining cone tank can pull a vacuum on itself if the headspace can't breathe.
