The Snyder Industries 200 Gallon Vertical Chemical Storage Tank in white is built for industrial chemical service where you need a tight footprint and a high specific-gravity rating. This vertical storage tank is molded from polyethylene, stands 69 inches tall on a 33.0 x 33.0-inch footprint, and tucks into a corner of a treatment skid or pump room without eating floor space. The walls carry a 1.9 specific-gravity rating, the number that decides whether a tank can safely hold a dense chemical for its full service life.
Will it work for your job?
This is a 200 gallon vertical tank with a 1.9 SG rating, meaning it is built for liquids up to 1.9 times the weight of water. A full tank of plain water comes in around 1,668 lbs, while the maximum rated contents weight runs to 3,169 lbs at the full SG rating. Size your slab and tie-downs to the heavier number, not the water figure. The molded-in fitting layout, shown on the technical drawing on this page, includes a flange, a 7" x 10" flat fitting, a 10" PE threaded-vented fitting, a fill cap with 7" access, and a second flat fitting for adding bulkhead fittings, level instrumentation, or a vent. Note that the 10" port is the vented fitting: it is your atmospheric vent path, so do not blind-plug every opening on a sealed chemical tank or you risk pulling a vacuum on draw-down or pressurizing during fill. If you are choosing between this and a taller or shorter vertical, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Chemical compatibility
The resin record for this tank reads as HDLPE but ends with a question mark, so confirm HDLPE versus XLPE (cross-linked) with us before you put it into chemical service. The two resins behave very differently with aggressive oxidizers and solvents, and at a 1.9 SG rating this tank is already near the top of the standard range. Compatibility below is drawn from our chemical-compatibility data and is concentration- and temperature-specific, so match your exact concentration and operating temperature before ordering fittings and gaskets.
Within its rating this tank is referenced for the following, with the recommended fitting and gasket materials: 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 (under 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; call to confirm). The gasket and fitting material matter as much as the tank wall: sodium hypochlorite, sulfuric acid, hydrogen peroxide and phosphoric acid call for Viton, peracetic acid for Aflas, and EPDM covers most salts and bases. Watch the cases that step up the fitting metal too: DEF at 32.5%, peracetic acid, propylene glycol and zinc orthophosphate are referenced with 316SS fittings, so a DEF buyer should not default to PVC. Browse the full Chemical Compatibility Database to confirm your chemical against concentration and temperature.
The mistake to avoid
The most common error on a 1.9 SG tank is ordering the wrong fitting and gasket package for the chemical. Putting a PVC fitting with an EPDM gasket on a strong oxidizer like sodium hypochlorite or sulfuric acid will fail at the seal long before the polyethylene wall does. Match the fitting and gasket materials listed above to your exact chemical, keep the vented 10" port open as your atmospheric path, and pair the build with the right instrumentation. For level monitoring on a chemical tank, our guide on level gauge selection for chemical service walks through radar versus ultrasonic versus hydrostatic versus magnetostrictive. If you are weighing single-wall storage against secondary containment, the Snyder Captor Plus 110% containment vs UL-142/SPCC comparison is worth a read, and the 200 gallon vertical liquid storage tank buyer's guide covers the full sizing picture.
