The Snyder Industries 3000 Gallon XLPE Vertical Double Wall Liquid Chemical Storage Tank is a cross-linked polyethylene (XLPE) double-wall vertical storage tank built for liquid chemical service, listed in white at a 3000-gallon working capacity. It stands 142 inches tall on a 102 x 102 inch footprint, with the integral secondary containment wall providing built-in spill protection without a separate dike. As a Snyder double-wall vertical tank with a 1.5 specific gravity rating, it suits chemical applications where the stored liquid is no heavier than 1.5 times the weight of water.
Will it work for your liquid?
The 1.5 specific gravity rating is the number that matters most before you order. Water weighs about 8.34 pounds per gallon; a full tank of plain water carries roughly 25,020 pounds, and at the maximum rated 1.5 SG the contents can reach 37,530 pounds. As long as your chemical's specific gravity is at or below 1.5, this tank is rated to hold it at full volume. The tank is plumbed through a flange outlet, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access for entry, fill, and routine inspection. Outlet flange size is not specified in the published drawing data, so confirm the flange diameter for your plumbing before ordering. See the technical drawing on this page for exact fitting locations and orientations, and use the Tank Sizing Calculator and Tank Sizing Guide if you are still confirming volume against your process. This is the vertical XLPE double-wall storage tank configuration buyers search for when they need secondary containment built into a single unit.
Chemical compatibility
This is an XLPE (cross-linked polyethylene) tank rated to 1.5 specific gravity. XLPE resists a broad range of aggressive chemicals, but compatibility always depends on concentration and temperature, so confirm your exact conditions against the OEM chemical-resistance chart before committing to chemical service. At a 1.5 SG rating, this tank is suited to the following, each shown with the concentration and the recommended fitting and gasket materials:
- Acetic Acid at 60% — PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% — PVC fittings, EPDM gaskets
- Calcium Chloride at 40% — PVC fittings, EPDM gaskets
- DEF at 32.5% — 316SS fittings, EPDM gaskets
- Ferrous Sulfate at 20% — PVC fittings, EPDM gaskets
- Magnesium Chloride at 30% — PVC fittings, EPDM gaskets
- Sodium Carbonate at 30% — PVC fittings, EPDM gaskets
- Urea Solution at 50% — PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM — PVC fittings, EPDM gaskets
A few common chemicals are heavier than this tank is rated to carry and need a higher 1.9 specific gravity tank instead of this 1.5 SG unit: Ethylene Glycol (details), Ferric Chloride (details), Ferric Sulfate (details), Hydrofluosilicic Acid (details, which also requires Viton gaskets rather than EPDM), Polyaluminum Chloride (details), Potassium Carbonate (details), Potassium Hydroxide (details), Propylene Glycol (details), and Sodium Thiosulfate (details). For any of these, ask about the 1.9 specific gravity version of this 3000-gallon Snyder vertical tank by calling 866-418-1777. For full concentration- and temperature-specific data on every chemical, see our Chemical Compatibility Database and cite the OEM chemical-resistance chart for your final selection.
The mistake to avoid
The most common error on a double-wall chemical tank this size is matching the resin and SG rating to the wrong chemical. Specifying a 1.5 SG XLPE tank for a heavier liquid such as ethylene glycol or ferric chloride overloads the wall over time. Confirm your chemical's specific gravity and concentration first, then match the fitting and gasket materials shown above — and note one exception: Hydrofluosilicic Acid requires Viton gaskets, not EPDM, so do not default every install to EPDM. One more site-planning check before you buy: at 142 inches (nearly 12 feet) tall, this tank will not clear a standard 10-foot building, so confirm overhead clearance and an access path, and at up to 37,530 pounds loaded, site it on an engineered, level pad rated for the full load. For double-wall containment planning, the Snyder Captor double-wall SPCC 40 CFR 112 walkthrough covers how integral secondary containment fits a compliance plan, and the 3000-gallon vertical storage tank buyer's guide walks through related configurations.
