The Snyder Industries 3600 Gallon XLPE Cone Bottom Tank is a full-drain crosslinked polyethylene vessel built for bulk chemical batching, blending, and metering where you need to empty completely between runs. Molded in Natural White crosslinked linear polyethylene with a 1.5 specific gravity rating, this 3,600-gallon cone tank stands 125 inches tall on a 102 x 102 inch footprint and is engineered to hold heavier-than-water process chemistry, not just water. If you have been searching for a Snyder cone bottom tank or an XLPE cone tank that drains clean, this is the size that anchors most mid-volume systems.
Will it work for your application
Start with weight, because a cone tank lives on a stand or structural support. Filled with water this tank carries 30,024 lb; loaded to its maximum rated contents at the 1.5 SG limit it reaches 45,036 lb. That is a 15,012 lb gap, so a stand sized to the water weight is under-rated by 50% for full-density 1.5 SG service - size your stand and foundation to the heavier number for whatever fluid you actually store. Run those loads through the Tank Sizing Calculator and review the Tank Sizing Guide before you commit to a structure. The 1.5 SG rating is the wall envelope: fluids up to 1.5 specific gravity are within the tank's design, and anything denser needs a higher-SG vessel. Because this is a full-drain cone, pair it with a matched stand and confirm fit using the Cone Bottom Tank Stand Compatibility Matrix. One siting check before you book freight: at 125 inches tall on a 102 x 102 inch footprint, this tank clears most standard door and ceiling openings only if you measure first, and it is a non-returnable LTL item once it ships.
Chemical compatibility
This tank is crosslinked polyethylene (XLPE) rated to 1.5 specific gravity. Within that envelope, the following chemicals are compatible at the concentrations shown, using the fitting and gasket materials noted. Compatibility is concentration- and temperature-specific, so verify your exact service conditions against the OEM chemical-resistance chart and our Chemical Compatibility Database before ordering fittings:
- Acetic Acid at 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% - PVC fittings, EPDM gaskets
- Calcium Chloride at 40% - PVC fittings, EPDM gaskets
- DEF (diesel exhaust fluid) at 32.5% - 316SS fittings, EPDM gaskets
- Ferrous Sulfate at 20% - PVC fittings, EPDM gaskets
- Magnesium Chloride at 30% - PVC fittings, EPDM gaskets
- Sodium Carbonate at 30% - PVC fittings, EPDM gaskets
- Urea Solution at 50% - PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
Note that DEF is the one chemical on this list that requires 316 stainless steel fittings rather than PVC or PP - everything else runs PVC or PP with EPDM gaskets. A few common chemicals are heavier than this tank's 1.5 SG rating and require a same-geometry 1.9 SG cone instead, which is available as a real product path - storing them in this 1.5 SG tank would be a mistake. Those include Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrofluosilicic Acid (the only chemical in this set needing Viton gaskets rather than EPDM), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, and Sodium Thiosulfate. If you store any of these, ask for the 1.9 SG version when you call.
The mistake to avoid
The single most common error on a chemical cone tank is matching the fittings and gaskets to the tank instead of to the chemical. The XLPE wall is the easy part; the bulkhead fittings and gaskets at the cone outlet are what fail first. As the list above shows, DEF needs 316 stainless steel, hydrofluosilicic acid (on the 1.9 SG path) needs Viton, and the rest run PVC or PP with EPDM - specify those materials at order time, not after a leak. Equally important: do not assume a 1.5 SG tank covers every chemical. Confirm your fluid's specific gravity against the 1.5 rating before committing the tank to chemical service, and review the technical drawing on this page for outlet and fitting locations. For instrumentation and labeling on a bulk chemical install, the tank level gauge selection guide and the NFPA 704 and GHS labeling guide walk through the requirements. If secondary containment is in scope, the Snyder Captor Plus 110% containment comparison covers the SPCC angle.
