The Chem-Tainer 200 Gallon HDPE Vertical Liquid Storage Tank (SKU TC3172IA) is a 72-inch-tall natural white polyethylene (HDPE) tank on a 31 x 31 inch footprint, built for liquid storage where a tall, small-footprint vertical fits the space you have. It holds 200 gallons - about 1,668 pounds full of water - and carries a 1.9 specific gravity rating, so the shell is engineered to safely hold contents up to a maximum rated weight near 3,169 pounds, well above the weight of plain water for the same volume.
Will it work for your job?
This is a vertical storage tank with the three dimensions that drive siting: 72 in tall, 31 in wide, 31 in deep. At a 31 x 31 in footprint and 72 in tall, it is a tall, narrow vertical with roughly a 2.3-to-1 height-to-width ratio - set it on a level, full-footprint pad rated for the loaded weight (up to about 3,169 lb at 1.9 SG) and secure it for its height. The 1.9 SG rating is the headline spec here: it means the wall is rated for liquids denser than water, up to a specific gravity of 1.9, so this is the rated choice when your liquid is heavier than water rather than a standard 1.5 SG water tank. If you are still choosing between this 200 gallon vertical tank and a larger size, run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide.
The mistake to avoid
The number that trips people up on a tank like this is specific gravity. The 1.9 SG rating tells you the heaviest liquid the wall is designed for; it does not tell you the liquid is chemically compatible with the polyethylene, which you still have to confirm before filling. Just as important on this SKU: fitting and gasket configuration is not published here. Call 866-418-1777 to confirm outlet size, bulkhead and gasket type, and lid location before ordering, so your plumbing and gasket material match both your layout and your liquid. The other consideration on HDPE verticals is the vapor space - wall stress can originate at the vapor-saturated headspace rather than the wetted liquid side, which routine liquid-side inspection can miss. Our guide on HDPE tank wall thickness at the vapor-saturated headspace walks through the ASTM D1998 sizing logic operators should understand.
Where it ships from and how freight works
This tank ships LTL freight, quoted live to your ZIP code. It is produced at two plants - Hanford, CA and Marked Tree, AR - so your freight is set from whichever named plant is nearest you. A 200 gallon vertical tank at roughly 1,668 pounds of water capacity is a palletized LTL load, not a parcel shipment, which is why freight is quoted to the destination rather than flat-rated.
