The Snyder Industries 1200 Gallon HDPE Vertical Chemical Storage Tank is a 1.9 specific-gravity-rated vertical storage tank built in high density linear polyethylene for demanding bulk chemical service. It stands 109 inches tall on a 60 x 60 inch footprint and holds 1,200 gallons. The 1.9 SG rating is the single most important spec to verify before you buy: it lets this Snyder vertical tank carry dense chemistries that would overwhelm a standard 1.5 SG water-grade tank on the same pad.
Will it work for your application?
Full of water at 8.34 lb/gal, the tank and contents weigh about 10,008 lb. Because the wall is rated to 1.9 specific gravity, the maximum rated contents weight climbs to 19,015 lb on the same 60 x 60 inch (25 sq ft) footprint - the 1.9 rating nearly doubles the allowable contents weight versus a 1.5 SG tank without adding any floor space. That means the foundation, secondary containment, and anchoring must be engineered for the loaded weight of the heaviest fluid you intend to store, not just water. Confirm your chemical's specific gravity against the 1.9 rating using the Tank Sizing Calculator and the Tank Sizing Guide before committing. The 60 x 60 inch footprint and 109 inch height make this a true vertical tank for tight pad space where you need volume without spreading out.
Fittings and access
Per the technical drawing on this page, this hdpe storage tank is configured with a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access. The vented threaded fitting matters for chemical service because closed bulk storage needs proper venting to handle fill, draw, and thermal breathing. The 15-inch manway access supports inspection, cleaning, and gauge or level-instrument installation. If you are specifying level monitoring, our guide on tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive trade-offs. Always confirm fitting locations and sizes against the technical drawing on this page before plumbing.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity. Start your verification at our Chemical Compatibility Database, then confirm against the OEM chemical-resistance chart for your exact chemistry - polyethylene resistance is concentration- and temperature-specific, so the right answer depends on resin, concentration, temperature, and the fitting and gasket materials you select. The 1.9 SG rating is precisely what makes the dense-acid entries below valid: chemistries like Sulfuric Acid (98%, details, CPVC fittings, Viton gaskets), Phosphoric Acid (85%, details, PVC, Viton), and Ferric Chloride (50%, details, PVC, EPDM) approach or exceed water density and would not be safe in a 1.5 SG tank, while lighter solutions such as DEF (32.5%, details, 316SS, EPDM), Ethylene Glycol (100%, details, PVC, EPDM), Propylene Glycol (details, PP/316SS, EPDM), and Urea Solution (50%, details, PP/PVC, EPDM) sit well under the rating. Additional chemicals confirmed compatible with this resin include Acetic Acid (60%, details, PP/PVC, EPDM), Aluminum Sulfate (50%, details, PVC, EPDM), Calcium Chloride (40%, details, PVC, EPDM), Ferric Sulfate (60%, details, PVC, EPDM), Ferrous Sulfate (20%, details, PVC, EPDM), Hydrochloric Acid (37%, details, PVC, Viton), Hydrofluoric Acid (48%, details, PP/PVC, Viton), Hydrofluosilicic Acid (26%, details, PP/PVC, Viton), Hydrogen Peroxide (50%, details, PVC, Viton), Magnesium Chloride (30%, details, PVC, EPDM), Peracetic Acid (30%, details, 316SS, Aflas), Polyaluminum Chloride (details, PVC, EPDM), Potassium Carbonate (50%, details, PVC, EPDM), Potassium Hydroxide (saturated, details, PVC, EPDM), Sodium Bisulfate (details, PVC/PP, EPDM), Sodium Bisulfite (details, PVC/PP, EPDM), Sodium Carbonate (30%, details, PVC, EPDM), Sodium Hypochlorite (under 16.5%, details, PVC, Viton), Sodium Thiosulfate (40%, details, PVC, EPDM), Zinc Orthophosphate (details, PP/316SS, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Match the fitting and gasket materials shown to your chemistry - two callouts catch buyers out: aggressive oxidizers and strong acids such as sodium hypochlorite, hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, and sulfuric acid specify Viton rather than EPDM, and a handful of chemistries (DEF, peracetic acid, propylene glycol, zinc orthophosphate) require 316 stainless steel fittings rather than PVC or PP. Putting an EPDM gasket on an oxidizer line, or a PVC fitting where stainless is called for, is a common and costly mistake.
