Snyder Industries 4400 Vertical HDPE ASTM Storage Tank For Sulfuric Acid 1.9 S.G.

The Snyder Industries 4400 is a 4,400-gallon vertical storage tank molded from high density linear polyethylene and rated to a 1.9 specific gravity, the high-SG build in Snyder's line for liquids substantially denser than water. Per its product listing it is configured for sulfuric acid service at 1.9 S.G., and the 1.9 rating is the number that separates it from a standard water tank. It stands 182 inches tall on a 90-inch diameter footprint, weighs 1,450 pounds empty, and carries an 18-inch lid for access. For dense or aggressive contents like acid, gasket and fitting material must be selected to match the chemistry, not just the tank shell.

Will it work for your site

Filled with water this 4400 gallon tank carries roughly 36,696 pounds; at its full 1.9 specific gravity rating the contents can reach up to 69,722 pounds, so the pad, ring wall, or slab beneath it has to be engineered for that load across the 90-inch diameter footprint. Both the 1.9 SG rating and the 120°F (48°C) maximum service temperature are governing limits — concentrated sulfuric acid is exothermic on dilution, so any hot-fill or heat-generating service needs review against that ceiling before you commit. Confirm your stored liquid's specific gravity against the 1.9 rating; overfilling with a denser contents is the single most common mistake on a high-SG vertical tank. If you are choosing between resin families for demanding acid duty, our guide on XLPE vs HDPE for high-SG sulfuric acid storage explains where crosslink density stops helping, and the Tank Sizing Calculator and Tank Sizing Guide help you match capacity and weight to your footprint.

Specs, fittings, and the technical drawing

Height 182 in, 90 in diameter, 1,450 lb empty, white HDLPE, 18-inch lid, 120°F max temperature, carrying manufacturer certification references 2285, 2282, and 3492. Outlet and fitting configuration are not specified in the listing data, so confirm the bulkhead and outlet layout from the technical drawing on this page or by phone before ordering — and match gasket or o-ring material to the stored chemical for any fitting. For polyethylene wall behavior under demanding vertical storage, our guide on HDPE tank wall thickness at the vapor-saturated headspace and ASTM D1998 sizing logic covers where these tanks actually wear. If your application calls for secondary containment, the Snyder Captor double-wall freeboard sizing guide walks through the usable-volume math for a double-wall build.
