The Snyder Industries 1000 Gallon XLPE Heavy Duty Cone Bottom Tank is built for full-drain chemical service where the contents need to empty completely and the chemistry is aggressive. It holds 1000 gallons in Natural White crosslinked linear polyethylene (XLPE) rated to a 1.9 specific gravity, with a 64 x 64 inch footprint and a 103 inch overall height. Because it is a cone bottom design, it requires a matching cone stand to support the sloped bottom and let it gravity-drain. This is the tank people search for when they look up a 1000 gallon cone bottom tank, cone tank, or XLPE cone bottom unit.
Will this tank work for your application?
The 1.9 specific gravity rating is the number that matters most here. It means the XLPE shell is engineered to carry contents up to 1.9 times the weight of water. A full load of water weighs roughly 8,340 lb, and the maximum rated contents weight at the 1.9 SG limit is about 15,846 lb, so confirm your chemical's specific gravity stays at or under 1.9 before you order. Crosslinked polyethylene gives this tank better resistance to stress cracking and aggressive oxidizers than standard HDPE, which is why it is specified for chemistry duty rather than plain water storage. At 103 inches tall on a 64 x 64 inch base, this is a tall, narrow profile, so the cone stand you pair it with must be rated to the full 15,846 lb maximum contents load and sited where the elevated stand height clears your fill and vent piping. To compare the two resins for your chemical, see our guide on Snyder XLPE vs HDPE: when crosslinking matters, and size the install with the Tank Sizing Calculator and Tank Sizing Guide.
Fittings and access
This unit ships with a flange, an 18 inch PE threaded and vented fitting, and a manway with 15 inch access for filling, gauging, and cleanout. The 15 inch access opening is the dimension to check first: on a sealed chemical tank it is the only entry, so confirm your cleanout tooling, mixer shaft, or level probe physically fits through it. The vented fitting matters on a chemical tank because it prevents vacuum or pressure buildup as you fill and draw down. Review the technical drawing on this page to confirm fitting locations and elevations against your piping plan, and match your stand to the cone using the cone bottom tank stand compatibility matrix. For a full walk-through of this size and geometry, read the 1000 gallon 45 degree cone bottom tank buyer's guide.
Chemical compatibility
This is an XLPE tank rated to 1.9 specific gravity, which is the heaviest-duty resin and SG rating offered for this geometry, so there is no higher-SG step-up to consider for this size. The shell handles a wide range of chemistries, but the wetted fittings and gaskets must match the chemical, and compatibility is concentration and temperature specific, so always verify against the OEM chemical-resistance chart before service. Based on the compatibility data for this resin and SG rating, the following are supported at the listed concentrations, grouped by the wetted-material package they require:
- PVC fittings, EPDM gaskets: Aluminum Sulfate (50%), Calcium Chloride (40%), Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Polyaluminum Chloride, Potassium Carbonate (50%), Potassium Hydroxide (saturated), Sodium Carbonate (30%), Sodium Thiosulfate (40%), and Ozonated Water (up to 10 PPM)
- PP/PVC fittings, EPDM gaskets: Acetic Acid (60%) and Urea Solution (50%)
- 316SS fittings, EPDM gaskets: DEF (32.5%)
- PP/316SS fittings, EPDM gaskets: Propylene Glycol
- PP/PVC fittings, Viton gaskets: Hydrofluosilicic Acid (26%)
There are five distinct wetted-material packages above, not one with a couple of exceptions. The 316SS fittings for DEF, the PP/316SS for propylene glycol, and the Viton gasket for hydrofluosilicic acid are not interchangeable with the PVC and EPDM default. Cross-reference your exact chemical and concentration in our Chemical Compatibility Database before finalizing the fitting and gasket package.
The mistake to avoid
The most common error on an XLPE cone bottom tank is mismatching the wetted hardware to the chemical. The 1.9 SG XLPE shell tolerates heavier and more aggressive contents than HDPE, but a PVC fitting or EPDM gasket that is fine for aluminum sulfate is the wrong choice for an oxidizer that needs Viton. Specify the fitting and gasket material per chemical, keep the vented fitting clear, never exceed the 1.9 SG rating, and confirm your cone stand carries the full 15,846 lb load.
This tank ships LTL from the Snyder plant in Lincoln, NE, with freight quoted live to your ZIP. Because it leaves from a single plant, transit distance to your ZIP is the dominant LTL cost driver on a tank this size, which is why freight is quoted live rather than as a flat number.
