The Snyder Industries 6500 Gallon XLPE Cone Bottom Tank is a 6,500-gallon crosslinked linear polyethylene (XLPE) vessel built for bulk chemical service that demands full-drain cone discharge and a heavy specific-gravity rating. It carries a 1.5 specific gravity rating, stands 273 inches tall on a 90 x 90 inch footprint, and is molded in black resin. This is the cone bottom tank to specify when you need complete gravity discharge of a dense liquid and a structure rated well above water weight.
Will this 6500 gallon cone bottom tank work for your job?
Filled with water, this tank carries 54,210 lb; at its 1.5 specific gravity rating it is engineered for up to 81,315 lb of rated contents. That headroom is the point of XLPE at 1.5 SG and the reason cone bottom buyers choose it over a flat-bottom water tank. Plan your stand, ring wall, or saddle for the loaded weight, not the empty shell, and confirm the 90 x 90 inch footprint clears your pad and any cone support structure. Standard fittings on this build include a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access. The 18-inch PE threaded/vented fitting supports venting for off-gassing chemicals, and the 15-inch manway access opens the tank for inspection and cleaning. Match every fitting, valve, and gasket to your chemical before install. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm capacity and loaded weight against your space, and the technical drawing on this page for exact fitting locations and clearances.
Chemical compatibility
This is an XLPE tank rated to 1.5 specific gravity. Crosslinked polyethylene resists a wider chemical range than standard polyethylene, but compatibility is concentration- and temperature-specific, so confirm your exact chemical, concentration, and operating temperature in our Chemical Compatibility Database and against the OEM chemical-resistance chart before ordering. At the 1.5 SG rating this tank is suited to Acetic Acid at 60%, Aluminum Sulfate at 50%, Calcium Chloride at 40%, DEF (diesel exhaust fluid) at 32.5%, Ferrous Sulfate at 20%, Magnesium Chloride at 30%, Sodium Carbonate at 30%, Urea Solution at 50%, and Ozonated Water up to 10 PPM. Fittings and gaskets are spec'd per chemical: most of these list PVC fittings with EPDM gaskets, while Acetic Acid and Urea Solution call for PP or PVC. If you are storing DEF or urea, note that DEF requires 316 stainless steel wetted fittings (not PVC) with an EPDM gasket. See Acetic Acid, Aluminum Sulfate, Calcium Chloride, DEF, Ferrous Sulfate, Magnesium Chloride, Sodium Carbonate, and Urea Solution. For Ozonated Water, confirm fittings and gaskets in the Chemical Compatibility Database or call 866-418-1777 before ordering.
Some heavier chemicals are compatible with XLPE but exceed this tank's 1.5 SG rating and require a higher-rated 1.9 SG tank instead: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrofluosilicic Acid (Viton gasket), Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, and Sodium Thiosulfate. If you are storing one of these, step up to the 1.9 SG version rather than overloading this tank.
The mistake to avoid
The most common error on a tank this size is sizing the stand and discharge plumbing to water weight. At 1.5 SG this vessel can legitimately hold 81,315 lb of product, far more than the 54,210 lb of water that fills it, so your cone support and foundation must be rated to the loaded chemical weight. Do not assume "polyethylene" alone tells you the chemical limit either: confirm whether your liquid needs this 1.5 SG XLPE build or a heavier 1.9 SG tank, and match fitting and gasket materials to the chemical, not to convenience. For chemical storage planning, the Cone Bottom Tank Stand Compatibility Matrix, level gauge selection guide, and tank labeling and signage compliance guide are worth reading before you order.
A 273-inch-tall, 6,500-gallon cone bottom tank is an oversize LTL move, so freight is a real line item worth pinning down early. This Snyder tank ships LTL freight from the Lincoln, NE plant, quoted live to your ZIP. Pull a quote with the Freight Cost Estimator before you commit, or call 866-418-1777 to confirm fittings, the 1.5 versus 1.9 SG decision, and freight before you order.
