The 2600 Gallon 45 Degree Plastic Cone Bottom Tank from Snyder Industries is built for full-drain chemical and process service where every drop needs to evacuate through the cone. Molded in white polyethylene and rated to 1.5 specific gravity, this cone tank stands 139 in tall on a 90 x 90 in footprint and holds 2,600 gallons. The 45-degree cone is the steepest of the common cone angles, so settling solids, slurries, and viscous batches slide to the outlet instead of bridging - the reason a cone bottom tank is specified for mixing, dosing, and sludge-prone duty.
Will it work for your application?
Confirm two numbers before you commit. First, weight: filled with plain water this Snyder cone bottom tank carries 21,684 lb, and at its full 1.5 SG rating the contents can reach 32,526 lb. A 45-degree cone bottom tank must sit in a matching steel or poly support stand that carries that load through the cone - it cannot sit flat on the ground, and the stand is a separately specified item that is not included in this listing. Size your stand and pad for the loaded weight, not the empty shell. Second, specific gravity: the 1.5 rating is the heaviest fluid this wall thickness is engineered to hold. Run the check yourself - divide your chemical's specific gravity by nothing and simply compare: if your fluid's SG exceeds 1.5, this wall is over its rating regardless of fill level. Use the Tank Sizing Calculator and Tank Sizing Guide to check working volume and headspace against your batch. For cone-angle selection across the line, the Norwesco Cone Bottom Tank Buyer's Guide walks through 15-degree vs 30-degree vs 45-degree tradeoffs, and our 300 gallon and 310 gallon 30-degree cone-with-stand guides show how the stand-and-cone system goes together at smaller volumes.
Fittings and ports
The factory fitting and outlet configuration is not specified in our listing data. Confirm the outlet size, bulkhead, and any side ports by phone before ordering, because cone-bottom plumbing must match your stand and discharge valve. This matters doubly in chemical service: the per-chemical fitting and gasket spec in the table below is what you must order on the bulkhead and discharge, so verify the as-shipped fitting and gasket material against your chemical's row before putting the tank into service.
Chemical compatibility
This is an HDLPE tank rated to 1.5 specific gravity. The resin code ends in a question mark in our data, so confirm HDLPE versus XLPE with us before putting any chemical into service - the two cross-link differently and that changes what they tolerate. The chemicals below are compatible with a 1.5 SG polyethylene tank at the listed concentrations, per OEM chemical-resistance data, which is concentration- and temperature-specific - always match your exact strength and operating temperature to the chart:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
DEF at 32.5% is listed as compatible with 316 stainless fittings and EPDM gaskets, making this tank a sound choice for diesel exhaust fluid storage. Note the fitting and gasket material called out for each chemical - the right tank wall with the wrong elastomer is still a leak.
Chemicals that need a higher-SG tank
Several common process chemicals are too dense or aggressive for the 1.5 SG wall and require a 1.9 specific-gravity tank instead. Use the same self-check: if your chemical's SG runs above 1.5, do not order this 1.5 SG tank - the same 2600-gallon 45-degree cone is offered in a 1.9 SG build, and you can call 866-418-1777 to spec it. The chemicals that call for the heavier wall are 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, and Zinc Orthophosphate. Note that sodium hypochlorite, sulfuric, hydrochloric, hydrofluoric, hydrofluosilicic, phosphoric, and hydrogen peroxide call for Viton seals and peracetic acid for Aflas rather than EPDM. Check the full Chemical Compatibility Database before specifying.
Freight and ordering
This large cone bottom tank ships LTL freight on a flatbed, quoted live to your ZIP. It ships from the Snyder Industries plant in Lincoln, Nebraska, so freight cost depends on distance to your site, and remember the support stand is a separate item to spec for the loaded weight before you buy. Use the Freight Cost Estimator for a freight estimate, and see the technical drawing on this page for the cone, outlet, and fitting layout. For questions on cone angle, stand sizing, fittings, or chemical fit for this 1.5 SG tank, call 866-418-1777 and we will confirm before you buy.
