The Snyder Industries 6000 Gallon XLPE Heavy Duty Cone Bottom Tank is built for full-strength chemical duty: crosslinked linear polyethylene (XLPE) construction rated to 1.9 specific gravity, in a 142" x 142" footprint standing 136" tall. The cone-bottom geometry drains completely, so there is no heel of product or settled solids left behind at the outlet, which is why cone bottoms are specified for batching, metering, and dosing chemistry rather than flat-bottom storage. This is a black tank, which blocks light transmission and discourages algae growth in stored solutions.
Will it hold your chemistry safely?
At 6000 gallons of plain water this tank weighs about 50,040 lb full; rated to its 1.9 SG limit, the maximum supported contents weight is roughly 95,076 lb. That gap is the whole point of the 1.9 rating: it lets you fill this tank with dense, heavy solutions like ferric chloride or calcium chloride brine to full height, where a lower 1.0 to 1.5 SG tank of identical dimensions could not safely carry the same liquid column. Those weights drive your foundation and cone-stand sizing, so run them through our Tank Sizing Calculator and review the Tank Sizing Guide before you pour a pad or order a stand. A cone-bottom tank of this size carries its full load on a stand or structural ring, so the support has to be matched to the tank; see the cone bottom tank stand compatibility matrix and the 6000 gallon cone bottom buyer's guide for stand pairing. The single biggest mistake on a tank like this is treating XLPE and HDPE as interchangeable, which they are not for chemical service. Crosslinking is what gives this tank its high-SG, aggressive-chemistry rating; the Snyder XLPE vs HDPE guide explains exactly when crosslinking matters.
Fittings and access
Per the technical drawing on this page, this tank is configured with a flange, a 12" x 13" fitting, an 18" PE threaded/vented fitting, and a manway with 15" access. That 15" manway access governs whether your mixer, level sensor, or cleaning equipment will fit through the top, and the vented fitting matters for the off-gassing chemistries here such as the acids. Match every wetted fitting and gasket to the chemical you are storing, because the fitting material that is correct for one solution is wrong for another, and the gasket choice changes by chemical. Confirm the exact outlet and fitting layout against the technical drawing before plumbing.
Chemical compatibility
This is an XLPE tank rated to 1.9 specific gravity, which qualifies it for the full-strength, heavy solutions that defeat lower-rated HDPE tanks. The following solutions are commonly stored in XLPE at this SG rating; always verify against the OEM chemical-resistance chart for your specific concentration and storage temperature, since both shift the recommendation. Acetic Acid 60% (PP/PVC fittings, EPDM gaskets, see acetic acid), Aluminum Sulfate 50% (PVC, EPDM, aluminum sulfate), Calcium Chloride 40% (PVC, EPDM, calcium chloride), DEF 32.5% (316SS fittings, EPDM, DEF), Ethylene Glycol 100% (PVC, EPDM, ethylene glycol), Ferric Chloride 50% (PVC, EPDM, ferric chloride), Ferric Sulfate 60% (PVC, EPDM, ferric sulfate), Ferrous Sulfate 20% (PVC, EPDM, ferrous sulfate), Hydrofluosilicic Acid 26% (PP/PVC fittings, Viton gaskets, hydrofluosilicic acid), Magnesium Chloride 30% (PVC, EPDM, magnesium chloride), Polyaluminum Chloride (PVC, EPDM, polyaluminum chloride), Potassium Carbonate 50% (PVC, EPDM, potassium carbonate), Potassium Hydroxide saturated (PVC, EPDM, potassium hydroxide), Propylene Glycol (PP/316SS fittings, EPDM, propylene glycol), Sodium Carbonate 30% (PVC, EPDM, sodium carbonate), Sodium Thiosulfate 40% (PVC, EPDM, sodium thiosulfate), Urea Solution 50% (PP/PVC fittings, EPDM, urea solution), and Ozonated Water up to 10 PPM (PVC fittings, EPDM gaskets; confirm directly via the Chemical Compatibility Database, as it has no dedicated page). One purchasing instruction falls straight out of this list: 16 of the 17 mapped chemicals run on EPDM gaskets, and only hydrofluosilicic acid requires Viton, so a multi-service gasket kit needs exactly one Viton set and EPDM for the rest. Browse the full Chemical Compatibility Database to confirm your exact chemistry. One note on resin: this tank's compatibility ratings depend on it being genuine XLPE, so confirm crosslinked versus linear polyethylene before committing to aggressive chemical service.
This Snyder cone bottom tank ships LTL freight from the stocking plant in Lincoln, NE, with freight quoted live to your ZIP. Because it ships from a single Nebraska plant as a large, low-density load, distance to your ZIP is the primary freight driver, so get a quote early through our Freight Cost Estimator, or call 866-418-1777 to confirm fittings, stand pairing, and chemical service before you order.
