The Snyder Industries 3000 Gallon Double Wall Liquid Chemical Storage Tank is a containment-integrated vertical tank built for high-specific-gravity chemical service. The primary tank is molded from High Density Linear Polyethylene (HDLPE) and carries a 1.9 specific gravity rating, which is the number that should drive your buying decision: it tells you the tank is engineered to hold dense liquids well beyond the weight of water. A built-in secondary containment wall surrounds the primary tank, so a single integrated unit handles both storage and spill capture for SPCC-style installations.
Will this tank work for my application?
This is a 3000 gallon vertical storage tank standing 142 inches tall on a 102 x 102 inch footprint. Filled with water it carries roughly 25,020 lb; loaded to its maximum rated contents it is engineered for up to 47,538 lb, which is what the 1.9 SG rating buys you over a standard water-only tank. Outfitting comes from the factory fitting package: a flange, an 18 inch PE threaded and vented connection, and a manway with 15 inch access. That 18 inch threaded/vented connection is the fill and vent path that matters most for off-gassing chemicals like sodium hypochlorite and peracetic acid, while the 15 inch manway access lets you inspect the primary tank inside the containment wall. Confirm the exact fitting locations and elevations against the technical drawing on this page before you set the pad and plumb the lines. If you are unsure whether 3000 gallons matches your throughput, the Tank Sizing Calculator and Tank Sizing Guide will help you confirm the volume.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity, which makes it suitable for a wide range of dense industrial chemicals. Always confirm your chemical, its concentration, and your operating temperature against the OEM chemical-resistance chart, which is concentration- and temperature-specific, before committing to chemical service. Compatible chemicals with their reference concentrations and recommended fitting and gasket materials include: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), Ethylene Glycol (100%, PVC, EPDM), Ferric Chloride (50%, PVC, EPDM), Ferric Sulfate (60%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrofluosilicic Acid (26%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Magnesium Chloride (30%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate (50%, PVC, EPDM), Potassium Hydroxide (saturated, PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate (30%, PVC, EPDM), Sodium Hypochlorite (<16.5%, PVC, Viton), Sodium Thiosulfate (40%, PVC, EPDM), Sulfuric Acid (98%, CPVC, Viton), Urea Solution (50%, PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). The fitting and gasket materials above are chemical-specific; match your fitting and gasket to the chemical you are storing, not to a single default.

The mistake to avoid
The costliest mistake on a double wall chemical tank is treating specific gravity as a formality. This tank is rated to 1.9 SG, so it can carry liquids nearly twice the density of water, but you must verify your chemical's actual specific gravity falls at or under that rating at your fill volume. If your chemical's specific gravity exceeds 1.9, this platform is not rated for it; call 866-418-1777 before ordering. The wrong fitting or gasket material is the second trap: sodium hypochlorite, sulfuric acid, and the peroxide-class chemicals above call for Viton or Aflas gaskets and acid-rated fitting bodies, not the EPDM that suits most salts and glycols. If you are storing DEF or another regulated chemical, the Snyder Captor double-wall SPCC 40 CFR 112 walkthrough covers how the integrated containment fits a compliance plan.
