The Snyder Industries 10000 Gallon Sulfuric Acid Double Wall Tank is a 226-inch-tall containment vessel built for high-density chemical duty, molded in HDLPE #880046 with a 1.9 specific gravity rating and an Opaque White exterior. As a double wall tank, it carries the primary storage vessel inside an integral outer shell, so a leak from the inner tank is captured by the outer wall rather than released to the pad. On a 142 x 142 inch footprint, it holds up to 10,000 gallons and is engineered for the density of sulfuric acid service at that 1.9 specific gravity rating.
Will it hold what you're storing
The number that governs a chemical double wall tank is the specific gravity rating. This one is rated to 1.9 SG, which is what lets it carry a dense liquid like concentrated sulfuric acid — that acid is far heavier than water, and a tank rated only to 1.0 or 1.5 would be overstressed by the same volume. At 10,000 gallons, plain water alone weighs about 83,400 lb, while the tank is rated to carry up to 158,460 lb of contents. Here is the tension a careful buyer should see: 10,000 gallons of true 1.9-SG liquid works out to roughly that same 158,460 lb, so the rating is consumed almost exactly at full volume. That means any thermal-expansion freeboard has to come off the fill level — not off the rating. Confirm your acid's actual density falls at or under 1.9 SG before you size the fill. The Tank Sizing Calculator and Tank Sizing Guide walk the numbers, and our guide on Snyder Captor double-wall freeboard sizing covers the density and thermal-expansion factors behind the volume you can actually use.
The mistake to avoid
The common error on a Snyder double wall acid tank is treating the outer wall as decorative and skipping the containment and pad engineering it is designed around. The double wall is your secondary containment, and it only performs if the tank sits on a properly sized, level foundation carrying the full 158,460 lb rated load — do not undersize the concrete. Our guide on concrete pad sizing for above-ground polyethylene tanks lays out the framework, and if this install is part of an SPCC program, the Snyder Captor double-wall SPCC 40 CFR 112 walkthrough maps how these tanks fit a spill-prevention plan.
Fittings and chemical service
One more discipline separates a working sulfuric acid install from a failure: the tank resin is only one part of a chemical-resistant system. Confirm your fitting, gasket, and valve materials are compatible with sulfuric acid before commissioning — the elastomer and hardware class, not the polyethylene shell, usually governs acid resistance. Fittings on this vessel are specified to your service, so call before you order and tell us the concentration and temperature you are running so the outlet package matches the chemistry.
