The Snyder Industries 6200 Gallon Heavy Duty Vertical Storage Tank is a crosslinked linear polyethylene (XLPE) vertical storage tank built to ASTM standards for high-density liquid duty. It stands 140 inches tall on a 120 x 120 inch footprint, holds 6,200 gallons in Natural White resin, and carries a 1.9 specific gravity rating - meaning it is engineered to hold contents up to 1.9 times the weight of water. At 1.9 SG this is Snyder's heavy-duty XLPE spec, the ceiling for this vertical line; there is nothing heavier-rated to step up to, so if your liquid runs heavy you are already specifying the top resin.
Will it work for your site?
Filled with plain water this tank carries roughly 51,708 pounds of contents, and its maximum rated contents weight climbs to 98,245 pounds when the full 1.9 SG allowance is used. Plan your foundation around those numbers, not the empty shell - a 120 x 120 inch pad has to carry the whole load. Note that the 6,200-gallon figure is gross shell volume: for a heavy or thermally-expanding liquid at the 1.9 SG allowance you must leave freeboard, so real usable volume is less. Our guide on freeboard sizing per ASTM D1998 works through the volume you can actually use, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm capacity before you commit. For above-ground placement the load path into the slab matters as much as the tank itself; our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework and where the ACI 318 boundary falls. Confirm 140 inches of vertical clearance and a full 120 x 120 inch (10 foot) set-down and access envelope before delivery, since a 6,200-gallon vertical cannot be tilted into place.
Fittings and access
Per the technical drawing on this page, this tank is configured with a flange, flat fitting pads (8 places at 45 degrees typical), and an 18-inch PE threaded manway for top access, inspection, and cleaning. The 18-inch PE threaded manway takes a matching 18-inch threaded lid and gasket - it is not a bolt-flange manway. The flat pads are landing points you drill and bulkhead yourself, so your bulkhead fittings and gaskets must be sized to the outlet you cut, not to a pre-set port. Match every connection to the drawing before you plumb the site.
XLPE vs HDPE - the decision to get right
The common mistake on a tank this size is treating XLPE and HDPE as interchangeable. Crosslinked polyethylene is the heavier-duty resin, which is what lets this vertical tank carry the 1.9 SG rating; a standard HDPE vertical tank is not the same specification. If you are weighing the two for a heavier or more demanding liquid, read Snyder XLPE vs HDPE: when crosslinking matters so you specify the right one the first time. For fire-water and reservoir duty at rural or remote sites, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
This XLPE vertical storage tank ships LTL from Snyder's plant in Marked Tree, Arkansas, quoted live to your ZIP. Freight is priced on the empty tank's shipping weight, not the 51,708 or 98,245 pound filled figures, so do not budget freight off the contents weight. Use our Freight Cost Estimator for a quote to your delivery ZIP, or call 866-418-1777 and we will size the freight and confirm the fitting configuration with you.
