The Snyder Industries 3600 Gallon Black Heavy Duty cone bottom tank (Snyder part 8050000N51) is built for full-drain chemical service, molded from high density linear polyethylene (HDLPE) and rated to a 1.9 specific gravity. That SG rating is the headline number for chemistry duty: it tells you the tank wall is engineered to hold contents up to 1.9 times the weight of water, so dense acids and concentrated salt solutions stay within the tank's structural envelope. At 3600 nominal gallons, this is a heavy-duty processing and storage vessel, not a water-only stock tank.
Will it work for your application?
This is a black cone bottom tank with a footprint of 102.0 x 102.0 inches and an overall height of 125 inches, so plan your pad and any support structure around a 102-inch square base. The cone geometry drives complete gravity drainage, which is why these tanks suit batch mixing, settling, and chemical dosing where you do not want a heel left behind. Fully filled with water the contents weigh 30,024 lb, and at the full 1.9 SG rating the tank is engineered for up to 57,046 lb of contents. A 102-inch square base carrying that load at 125 inches tall is a tall, dense cone, so build the anchoring, seismic, and stand calculations around the rated weight and the height, not the water-only figure. Use those two weights to size your foundation before you commit to a location. If you are still deciding between sizes, work the volume against your batch and turnover needs with our Tank Sizing Calculator and Tank Sizing Guide. A cone bottom tank of this scale almost always rides on a steel or poly stand; confirm the match using the Cone Bottom Tank Stand Compatibility Matrix so the cone, lift legs, and stand ring line up.
Chemical compatibility
This tank is HDLPE with a 1.9 specific gravity rating. Because the resin marker carries an HDLPE designation, confirm HDLPE versus XLPE (crosslinked) construction with us before placing the tank into chemical service - the two resins behave differently under oxidizers and certain solvents, and that choice is covered in Snyder XLPE vs HDPE: When Crosslinking Matters. At the 1.9 SG rating, this tank is suited to a broad chemical range, including Acetic Acid (60%), Aluminum Sulfate (50%), Calcium Chloride (40%), DEF (32.5%), Ethylene Glycol (100%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Hydrochloric Acid (37%), Hydrofluoric Acid (48%), Hydrofluosilicic Acid (26%), Hydrogen Peroxide (50%), Magnesium Chloride (30%), Peracetic Acid (30%), Phosphoric Acid (85%), Polyaluminum Chloride, Potassium Carbonate (50%), Potassium Hydroxide (saturated), Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Carbonate (30%), Sodium Hypochlorite (<16.5%), Sodium Thiosulfate (40%), Sulfuric Acid (98%), Urea Solution (50%), Zinc Orthophosphate, and Ozonated Water (up to 10 PPM). Fitting and gasket material matters as much as the tank wall: most of these run PVC or PP fittings with EPDM gaskets, but the aggressive oxidizers and strong acids change the rules - Hydrochloric, Hydrofluoric, Hydrofluosilicic, Hydrogen Peroxide, Phosphoric, and Sodium Hypochlorite call for Viton gaskets; Sulfuric Acid at 98% needs CPVC fittings with Viton. DEF at 32.5% is a purity-critical service rather than a corrosion one, so it runs 316 stainless fittings with EPDM; Peracetic Acid also calls for 316 stainless, paired with an Aflas gasket. Always confirm against the OEM chemical-resistance chart at your specific concentration and temperature, since both shift the rating, and cross-check on our Chemical Compatibility Database.
The mistake to avoid
The most expensive error on a cone bottom tank this size is matching the wrong fitting or gasket to the chemical, not the tank itself. The HDLPE wall at 1.9 SG handles the chemicals above, but a PVC fitting or EPDM gasket on a Viton-required service (or CPVC on Sulfuric Acid) will fail long before the tank does. The second is under-building the support: this tank reaches 57,046 lb at full rated SG, and a stand sized for water-only weight will not carry a dense chemical load. Specify the fitting train and the stand from the rated weight, not the water weight. For monitoring on a tall cone tank, match the level sensor to the chemistry and geometry using our Tank Level Gauge Selection guide, and if you are evaluating containment for the install, review the Snyder Captor Plus 110% Containment comparison. You can see the technical drawing on this page for the full dimensional and fitting layout.
