The Norwesco 1635 Gallon Horizontal Elliptical Leg Tank in Black is a polyethylene horizontal leg tank built for transporting and field-applying liquid loads up to a 1.5 specific gravity rating. Cradled on its molded legs with a 71 x 142 inch footprint and a 58 inch height, this horizontal tank is engineered to sit on a skid, trailer, or applicator frame and ride stable on the move. At 1635 gallons of nominal capacity, it covers the haul jobs where a smaller portable utility tank runs short.
Will it work for your load?
Start with weight, because that is what decides your trailer, your axles, and your tie-downs. Filled with plain water this tank carries roughly 13,636 lb of contents; at the full 1.5 specific gravity rating it is built to hold up to about 20,454 lb of contents weight. Those numbers are the contents alone, before you add the tank, the frame, and the trailer, so size your running gear against the loaded number, not the empty one. The tank's own dry weight is not listed here, so confirm it when you request your freight quote to close out the loaded-GVW math. If you are matching this tank to a denser liquid or working back from a target payload, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit. The 1.5 specific gravity rating is the ceiling for this tank body: stay at or under it, and confirm your liquid's density falls inside that limit. Note the 142 inch length too - confirm your trailer or skid deck runs long enough, and plan on dimensional LTL freight on a tank this size.
Chemical compatibility
This tank is polyethylene rated to 1.5 specific gravity. The resin reads as HDLPE but is not yet confirmed - verify HDLPE versus XLPE against Norwesco before placing this tank into any chemical service. Compatibility below is drawn from the manufacturer chemical-resistance chart and is concentration- and temperature-specific; always confirm your exact concentration and operating temperature against that chart before filling. Fitting and outlet configuration is not listed on this page - call 866-418-1777 to confirm bulkhead and outlet sizes and to spec the correct PP, PVC, CPVC, or 316SS fitting and EPDM, Viton, or Aflas gasket for your liquid.
Within the 1.5 specific gravity rating, this tank handles acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS, EPDM), ferrous sulfate (20%, PVC, EPDM), magnesium chloride (30%, PVC, EPDM), sodium carbonate (30%, PVC, EPDM), urea solution (50%, PP/PVC, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM). Match the fitting and gasket material to the liquid you are running - the chart calls for specific elastomers, and the wrong gasket is the most common field failure on an otherwise compatible tank.
The mistake to avoid
Several common applicator and treatment chemicals exceed the 1.5 specific gravity rating of this tank and require a 1.9 specific gravity tank instead - stepping up is not only a density and wall-thickness question but a sealing-material one. If your service includes ethylene glycol, ferric chloride, ferric sulfate, hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, peracetic acid, phosphoric acid, polyaluminum chloride, potassium carbonate, potassium hydroxide, propylene glycol, sodium bisulfate, sodium bisulfite, sodium hypochlorite, sodium thiosulfate, sulfuric acid, or zinc orthophosphate, do not put it in this 1.5-rated tank - move up to a 1.9 specific gravity body. Watch the gasket call especially: sulfuric acid wants CPVC fittings with a Viton gasket, peracetic acid wants 316SS with Aflas, and hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, phosphoric acid, and sodium hypochlorite all need Viton rather than EPDM. Check both the tank rating and the gasket on the chemical compatibility chart, and see the technical drawing on this page for body geometry, before you order.
Freight
This horizontal leg tank ships LTL freight, quoted live to your ZIP, typically from the closest stocking Norwesco plant - Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Shawnee, OK; St. Bonifacius, MN; or Tooele, UT. Pulling from the nearest of those seven plants keeps transit short and freight reasonable on a tank this size. Get your freight quote with the Freight Cost Estimator, or call us at 866-418-1777 and we will quote it, confirm dry weight, and help you spec the right fittings and gasket for your liquid.
