The Norwesco 3250 Gallon HDPE Horizontal Leg Tank (N-44604) is a workhorse-scale horizontal leg tank built for hauling and field transport, where the load self-levels low and rides flat on its integrated leg supports. Molded in blue polyethylene, it carries a 1.9 specific gravity rating - the spec that lets it haul dense liquids and concentrated agricultural and water-treatment chemicals that would overload a standard 1.5 SG tank. At 81 in. high, 88 in. wide, and 152 in. long, it sits on an 88.0 x 152.0 in. footprint. Measure your trailer deck or skid frame against those numbers before you commit, because this is a large-format horizontal that needs full support under the belly, not just under the legs.
Will it work for your job?
Full of water this tank weighs roughly 27,105 lb, and at its maximum rated contents it carries up to 51,500 lb - that maximum is the number that governs your trailer rating, axles, and tie-down plan, not the water figure. Run the load math on the Tank Sizing Calculator and check the Tank Sizing Guide before you spec a chassis, because a 3,250-gallon horizontal at 1.9 SG is a DOT and structural decision as much as a tank decision. For outlet locations, leg spacing, and fitting placement, call us at 866-418-1777 to confirm the exact configuration before you plumb or build a mount, so everything lines up the first time.
Chemical compatibility
This tank is rated to 1.9 specific gravity. Its resin family is not confirmed in our records - the marked resin is HDLPE but needs verification, so confirm whether it is HDLPE or XLPE with us before putting it into chemical service, because the resin family changes what you can safely store. The compatibility below is drawn from the OEM chemical-resistance chart and is always concentration- and temperature-specific; verify your exact concentration and operating temperature against that chart, and confirm the resin, before ordering for any chemical duty.
At 1.9 SG and the correct resin, the chart supports these chemicals, each with the fitting and gasket materials it requires: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets); Aluminum Sulfate (50%, PVC, EPDM); Calcium Chloride (40%, PVC, EPDM); DEF (32.5%, 316SS, EPDM); Ethylene Glycol (100%, PVC, EPDM); Ferric Chloride (50%, PVC, EPDM); Ferric Sulfate (60%, PVC, EPDM); Ferrous Sulfate (20%, PVC, EPDM); Hydrochloric Acid (37%, PVC, Viton); Hydrofluoric Acid (48%, PP/PVC, Viton); Hydrofluosilicic Acid (26%, PP/PVC, Viton); Hydrogen Peroxide (50%, PVC, Viton); Magnesium Chloride (30%, PVC, EPDM); Peracetic Acid (30%, 316SS, Aflas); Phosphoric Acid (85%, PVC, Viton); Polyaluminum Chloride (PVC, EPDM); Potassium Carbonate (50%, PVC, EPDM); Potassium Hydroxide (saturated, PVC, EPDM); Propylene Glycol (PP/316SS, EPDM); Sodium Bisulfate (PVC/PP, EPDM); Sodium Bisulfite (PVC/PP, EPDM); Sodium Carbonate (30%, PVC, EPDM); Sodium Hypochlorite (under 16.5%, PVC, Viton); Sodium Thiosulfate (40%, PVC, EPDM); Sulfuric Acid (98%, CPVC, Viton); Urea Solution (50%, PP/PVC, EPDM); and Zinc Orthophosphate (PP/316SS, EPDM). Ozonated Water (up to 10 PPM, PVC, EPDM) is supported as well - ask us for the reference when you call. The most common mistake on a chemical haul tank is matching the resin correctly but pairing the wrong gasket: use Viton where the chart calls for it on oxidizers like sodium hypochlorite and hydrogen peroxide, and Aflas for peracetic acid - an EPDM gasket in those services fails fast. If your contents exceed a 1.9 SG, call 866-418-1777 before ordering. See the full chemical compatibility reference for any chemical not listed here.
Freight
This is an LTL freight item, quoted live to your ZIP. It ships from the nearest of Norwesco's plants - Fairfield, TX; St. Bonifacius, MN; or Washington Court House, OH - and on a 51,500 lb max-load tank, plant proximity is the single biggest variable in your freight cost. Run your ZIP through the Freight Cost Estimator before you compare prices anywhere, because the same tank can land very differently depending on which plant is closest. For build and classification context on Norwesco horizontal and leg tanks, the guide on Norwesco applicator and leg tanks for fertilizer and the overview of 49 CFR agricultural-exemption and DOT classification are worth reading; if you are blending fertilizer in this tank, the deep dive on fertilizer-blend tank stratification covers the mixing and field-verification steps that catch a stratified load before it runs off-spec.
