The Snyder Industries 6000 Gallon XLPE Cone Bottom Tank is a 6,000-gallon crosslinked linear polyethylene (XLPE) vessel built for sustained chemical service, rated to 1.5 specific gravity. It stands 136" tall on a 142" x 142" footprint and ships in natural white so you can read liquid levels without opening the manway. The full cone discharge drains the vessel completely, which is what most operators are after when they search for a cone bottom tank, cone tank, or XLPE Snyder cone for batch mixing, settling, or full-evacuation chemical storage.
Will it work for your application?
Water at full capacity puts roughly 50,040 lb of contents in this tank; at its maximum 1.5 specific gravity rating it carries up to 75,060 lb. That weight rides entirely on the support structure, so the cone must sit in a matched steel stand sized for a 142" diameter cone bottom tank - never set it on a flat pad. Plan for the 136" tank height plus your stand height when you check door, ceiling, and crane clearance. The factory fitting package shown on the technical drawing on this page includes a flange, a 12" x 13" fitting, an 18" PE threaded/vented fitting, and a manway with 15" access. That 15" access opening governs what gauging, mixing, and cleanout hardware will physically fit, so size your instrumentation around it. Confirm your inlet, outlet, and vent line sizes against those fitting locations before you order, and use the Tank Sizing Calculator and Tank Sizing Guide to verify the working volume and head pressure your process needs.
Chemical compatibility
This is an XLPE (crosslinked polyethylene) tank with a 1.5 specific gravity rating. Per the OEM chemical-resistance chart, which is concentration- and temperature-specific, the 1.5 SG XLPE build is suitable for the following at the concentrations noted, with the listed fitting and gasket materials:
- 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
Always match the wetted hardware to the chemical, not just the tank wall. Note that DEF is the one rated chemical on this list that requires 316SS wetted hardware rather than PVC or PP - do not reuse PVC fittings on a DEF install. Several chemicals people try to store in a cone tank are NOT rated for the 1.5 SG build and require a higher 1.9 specific gravity tank instead - among them Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, and Sodium Thiosulfate, all with PVC or PP wetted hardware and EPDM gaskets. Hydrofluosilicic Acid also needs the 1.9 SG tank, and it differs in that it requires Viton gaskets rather than EPDM - worth flagging if you are in fluoride or water-treatment service. If your process uses any of those, ask us about the matching 1.9 SG vessel before you buy, and check the full Chemical Compatibility Database against your exact chemistry and concentration.
The mistake to avoid
The single most common error on a tank like this is matching the specific gravity to water instead of the chemical. A 1.5 SG rating means the tank wall is engineered for fluids up to 1.5 times the density of water - run a denser product, or one off the rated list above, and you risk wall failure. Confirm both the chemical's compatibility and its specific gravity against the OEM chart before filling. For containment requirements, the Snyder Captor Plus 110% Containment vs UL-142 comparison walks through your secondary-containment options, the cone bottom stand compatibility matrix covers stand selection, the 6000 gallon 15-degree cone bottom buyer's guide goes deep on this size class, and the level gauge selection guide helps you instrument it correctly.
