The Snyder Industries 1500 Gallon Sulfuric Acid Double Wall Tank is a 1,500-gallon double-wall containment vessel purpose-named for sulfuric acid service, molded in Opaque White HDLPE (resin #880046) and rated to a 1.9 specific gravity. That 1.9 rating is the number that matters most on this tank: it is built to hold dense, aggressive contents that a standard 1.0 or 1.5 SG water tank is not designed to carry. The integral outer wall gives you built-in secondary containment, so one tank serves as both the primary vessel and the catch basin in a single footprint.
Will it work for your site
The tank stands 76 inches tall on a 93 x 93 inch square footprint, so plan your pad and clearance around that 93-inch width plus room to work around the fittings. Design the pad and anchoring for the loaded weight of the fluid you will actually store: at the tank's maximum 1.9 SG rating, the contents can reach roughly 23,769 pounds, and sizing to the plain-water figure of about 12,510 pounds would under-spec this exact tank. Note too that 1,500 gallons is the nominal capacity; once you apply thermal-expansion freeboard for a dense double-wall unit, usable volume lands below that number. Our Tank Sizing Calculator and Tank Sizing Guide help you work it through, and the Snyder Captor double-wall freeboard sizing guide (ASTM D1998) shows exactly how density and thermal expansion cut into the volume you can actually use.
The mistake to avoid
Do not treat the 1.9 SG structural rating as a chemical clearance for your specific fluid. The rating confirms the tank can structurally carry contents up to 1.9 times the density of water; it does not by itself confirm that the resin, gaskets, and fittings are compatible with your exact acid concentration and temperature. Before you put this tank into service, run the short checklist: (a) confirm resin #880046 against Snyder's chemical-resistance chart for your concentration and temperature, (b) verify the fitting material, and (c) verify the gasket and O-ring elastomer. Because double-wall tanks route connections through both walls, check every fitting shown on the drawing against your piping plan before you order. For containment and spill-control planning around above-ground poly tanks, the SPCC 40 CFR 112 compliance walkthrough and the concrete pad sizing framework (ACI 360R-10) are worth reading before installation.
