Snyder Industries 500 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank

The Snyder Industries 500 Gallon ASTM XLPE Vertical Storage Tank is a black, crosslinked linear polyethylene vertical tank rated to 1.9 specific gravity, which is what makes it a workhorse for storage duty well beyond plain water. It stands 77 inches tall on a 53 x 53 inch footprint, so plan the pad and any low overhead before it arrives. Below are the three things worth settling before you buy: whether it fits your job, how it ships, and the one mistake to avoid.

Will this 500 gallon vertical tank work for your site?

Full of water this tank carries roughly 4,170 pounds of contents, but because the crosslinked shell is rated to a 1.9 specific gravity it is engineered to hold denser liquids up to about 7,923 pounds at that maximum rating. Size your slab and any anchoring to the 7,923-pound figure if you will ever store a liquid heavier than water, not the 4,170-pound water number. The 53 x 53 inch square footprint and 77 inch height determine your slab size and clearance, so confirm both against the technical drawing on this page. If you are matching capacity to demand, the Tank Sizing Calculator and Tank Sizing Guide walk you through it, and the Snyder XLPE vs HDPE guide explains when crosslinking is the right call for chemistry duty.

Fittings and access

This vertical storage tank comes configured with a flange fitting, an 18-inch polyethylene threaded and vented lid, and a manway with 15-inch access for interior reach during cleaning and inspection. Verify the fitting locations and heights against the technical drawing before you plumb the outlet or size a fill line, since inlet and outlet placement drives your connection layout.

The mistake to avoid

The single most common error with a crosslinked (XLPE) tank is treating the 1.9 specific gravity rating as a green light for any liquid. The rating governs the weight the shell can safely carry, not chemical resistance. For anything other than water, confirm the specific gravity of your actual contents and its compatibility with XLPE before filling, and never exceed the maximum rated contents weight. One more failure mode people miss: fitting and manway gaskets are a separate compatibility check from the shell, so confirm the seal and gasket material is rated for your liquid, not just the XLPE tank wall. For heavier storage duty and freeboard planning, the ASTM D1998 freeboard guide and the concrete pad sizing framework are worth reading first.

This tank ships empty as a single poly shell from the Snyder plant in Marked Tree, Arkansas, so its LTL freight class is driven by cube (77 x 53 x 53 inches), not the 4,170-pound loaded weight.
