The Snyder Industries 5500 Gallon Heavy Duty Cone Bottom Tank is built for the toughest concentrated-chemistry duty in industrial water treatment and process service. Molded in black Crosslinked Linear Polyethylene (XLPE) and rated to 1.9 specific gravity, this cone bottom tank stands 241 inches tall on a 90 x 90 inch footprint, holding 5,500 gallons that drains completely through its angled bottom. If you have been searching for a Snyder XLPE cone tank that can carry heavy, aggressive solutions and self-empty without a sump, this is the size class that does it.
Will it work for your application?
The XLPE wall and 1.9 SG rating are the two numbers that matter here. Crosslinked polyethylene resists stress cracking and chemical attack better than standard HDPE, which is why this tank is specified for concentrated acids and salts rather than plain water storage. At full water capacity the tank carries roughly 45,870 pounds; loaded to its maximum rated 1.9 SG contents it carries up to 87,153 pounds, so the stand, ring wall, or concrete pad beneath it must be engineered for that load. Cone bottom tanks need full elevated support around the cone, never a flat slab. The 90 x 90 inch footprint and 241-inch height mean this is almost always an outdoor or tall-bay installation, so verify overhead clearance, fill access at the top, and door or bay height for a 241-inch tank before delivery. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm volume and weight against your structure, review the Cone Bottom Tank Stand Compatibility Matrix before ordering a stand, and see the 5500 Gallon Cone Bottom Tank Buyer's Guide for a walkthrough of this size class.
Chemical compatibility
This is an XLPE cone bottom tank rated to 1.9 specific gravity, which is what allows it to hold the heavy, concentrated solutions below. Standard HDPE rotomolded tanks are typically rated near 1.5 SG, so the 1.9 rating is itself corroborating evidence of the crosslinked resin; because XLPE can still be confused with HDPE in catalog data, confirm the resin is XLPE before committing the tank to chemical service. The following chemicals are compatible with the XLPE wall when paired with the fitting and gasket materials shown; always match concentration and temperature to the OEM chemical-resistance chart for this resin before finalizing.
- 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
- Ethylene Glycol (100%) — PVC fittings, EPDM gaskets
- Ferric Chloride (50%) — PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) — PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) — PVC fittings, EPDM gaskets
- Hydrofluosilicic Acid (26%) — PP/PVC fittings, Viton gaskets
- Magnesium Chloride (30%) — PVC fittings, EPDM gaskets
- Polyaluminum Chloride — PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) — PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) — PVC fittings, EPDM gaskets
- Propylene Glycol — PP/316SS fittings, EPDM gaskets
- Sodium Carbonate (30%) — PVC fittings, EPDM gaskets
- Sodium Thiosulfate (40%) — PVC fittings, EPDM gaskets
- Urea Solution (50%) — PP/PVC fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) — PVC fittings, EPDM gaskets
The most common mistake on a chemical cone tank is getting the elastomer wrong, so match every wetted material to your chemistry: EPDM gaskets cover the salts, glycols, and carbonates above, hydrofluosilicic acid requires Viton, and DEF and propylene glycol call for 316 stainless fittings. Fittings and gaskets are not included with the tank and must be specified separately per chemistry. The 1.9 SG rating is the ceiling for this size and family, so it covers every solution listed; if your actual chemistry exceeds 1.9 SG or runs hot, call us to confirm rather than assume a heavier-rated tank exists. Compare your duty cycle in our Chemical Compatibility Database, and if you are weighing crosslinked versus standard polyethylene, read Snyder XLPE vs HDPE: When Crosslinking Matters.

Freight and ordering
This tank ships LTL from Snyder's Lincoln, NE plant, freight quoted live to your ZIP. At 241 inches tall and well over a ton empty, it moves as a single oversized piece, so accurate delivery details matter. Get a real number with our Freight Cost Estimator, or call 866-418-1777 to lock in your configuration, confirm the exact cone angle and fittings for your chemistry, and arrange delivery. See the technical drawing on this page for dimensional detail before you finalize your stand or pad.
