The Snyder Industries 5500 Gallon XLPE Heavy Duty Cone Bottom Tank is built for the chemistry that ordinary water-tank polyethylene cannot survive long term. Molded in crosslinked linear polyethylene (XLPE) and rated to 1.9 specific gravity, this 5,500-gallon vessel measures 90 inches across the base and stands 241 inches tall on a 90.0 x 90.0 inch footprint, so it must be set on a matched Snyder cone-bottom stand rather than free-standing. The natural white wall lets operators read fluid level at a glance, and the full-drain cone geometry suits dosing, settling, and batch chemical service.
Will it work for your application?
The 1.9 SG rating is the number that matters here: it tells you how heavy a liquid this tank wall is engineered to hold. Plain water weighs in at roughly 45,870 lb when the tank is full, but at its maximum rated content density the same tank carries up to 87,153 lb. That is nearly double the water weight, and that headroom is exactly why XLPE cone bottoms get specified for dense coagulants like ferric chloride and ferric sulfate instead of standard HDPE water tanks. Size the stand, the slab, and any anchoring to the loaded weight, not the dry footprint weight. The Tank Sizing Calculator and Tank Sizing Guide help you confirm the gallons and weight against your batch volume before you commit, the cross-brand cone bottom tank stand compatibility matrix covers stand selection across Norwesco, Snyder, and Enduraplas, and the 5500 gallon 30 degree cone bottom tank buyer's guide walks the full size class.
Chemical compatibility
This tank is crosslinked polyethylene (XLPE) rated to 1.9 specific gravity, which is what lets it hold the dense oxidizers and concentrated salts that would shorten the life of a lighter-walled HDPE tank. Compatibility always depends on concentration and temperature, so verify every chemical against the manufacturer's chemical-resistance chart for your exact conditions before filling, and match fittings and gaskets to the chemical, not just the tank. The following are compatible with this XLPE 1.9 SG tank when plumbed correctly:
- 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
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM 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 Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Watch these three exceptions to the PVC/EPDM default: Hydrofluosilicic Acid needs Viton gaskets rather than EPDM, DEF calls for 316SS stainless fittings, and Propylene Glycol calls for PP or 316SS fittings rather than PVC. Ozonated Water also carries a 10 PPM ceiling, so ozone service is concentration-capped, not unlimited. Every chemical on this list is already within the 1.9 SG rating, so no denser-rated tank is needed for any of them; the only reason to step up would be a liquid heavier than the rated maximum content density of roughly 1.9 SG. Confirm each chemical against the OEM chemical-resistance chart at your concentration and temperature, and start with our Chemical Compatibility Database.

Avoid the costly mistake
The most expensive error on a tank this size is under-rating the wall for your liquid. The 1.9 SG rating is not a suggestion: filling an XLPE cone bottom with a denser solution than it is built for, or treating the dry footprint weight as the load the stand must carry, is how tanks and stands fail. Spec the stand and foundation to the loaded weight near 87,153 lb, plumb fittings and gaskets to the chemical, and where secondary containment is required, review the Snyder Captor Plus 110% containment vs UL-142 comparison for how poly containment stacks up against steel for SPCC duty.
