The 7400 Gallon Heavy Duty Cone Bottom Tank from Snyder Industries is a polyethylene cone bottom tank built for full-discharge bulk chemical service at scale. It stands approximately 160 inches (13-plus feet) tall on a 142-inch diameter footprint and carries a 1.9 specific gravity rating, which is the heavy-duty ceiling for this tank, with no higher-SG variant offered. That 1.9 rating is what lets it carry dense solutions where a standard 1.5 SG tank would be under-rated, and the cone geometry routes contents toward the outlet rather than letting them settle on a flat floor.
Will it work for your application?
At 7400 gallons, plain water (1.0 SG) fills this tank to roughly 61,716 pounds, and the 1.9 SG wall rating allows a maximum rated contents weight near 117,260 pounds. Run that math before you commit: for a 1.9 SG chemical, the liquid alone approaches that 117,260-pound ceiling at full volume, leaving little margin, so confirm your operating SG against the 1.9 rating rather than assuming you can always fill to the top. The cone bottom is why buyers pick this shape over a flat-bottom vertical, but "complete drain" is a function of correct outlet diameter and cone-angle selection, not the shape alone, which matters because several services below (ferric chloride, ferric sulfate, aluminum sulfate, polyaluminum chloride) carry solids that can bridge a small outlet. Size the outlet against your slurry behavior with our cone-bottom outlet sizing guide, and confirm capacity against your duty cycle with the Tank Sizing Calculator and Tank Sizing Guide. Dimensions and outlet detail are on the technical drawing on this page. Note that fitting configuration (outlet size, fill and vent ports, lid) is not published for this SKU, so confirm the exact port arrangement with us at 866-418-1777 before you order rather than assuming a stocked layout.
Chemical compatibility
This is a polyethylene tank rated at 1.9 specific gravity. The resin is recorded as HDLPE in our data but ends with a question mark, so confirm HDLPE versus XLPE with us before committing this tank to chemical service, since crosslinked and linear polyethylene differ in chemical and stress-crack performance. Compatibility below is drawn from our chemical compatibility data and is always concentration- and temperature-specific, so verify your exact conditions against the OEM chemical-resistance chart before ordering. Fitting and gasket materials are specified per chemical:
- 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
- Hydrochloric Acid (37%) — PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) — PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) — PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) — PVC fittings, Viton gaskets
- Magnesium Chloride (30%) — PVC fittings, EPDM gaskets
- Peracetic Acid (30%) — 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) — PVC fittings, Viton 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 Bisulfate — PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite — PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) — PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<16.5%) — PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) — PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) — CPVC fittings, Viton gaskets
- Urea Solution (50%) — PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate — PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) — PVC fittings, EPDM gaskets
The chemicals listed without a concentration — polyaluminum chloride, propylene glycol, sodium bisulfate, sodium bisulfite, and zinc orthophosphate — have no concentration ceiling on record here, so confirm your exact concentration against the database before service. Match fitting and gasket material to your chemical from the list above, and browse the full Chemical Compatibility Database for concentration and temperature detail.
The mistake to avoid
The expensive error on a tank this size is mismatching the gasket to the chemical. Strong oxidizers and acids here — sulfuric, phosphoric, hydrofluoric, hydrogen peroxide, sodium hypochlorite — call for Viton rather than EPDM, while peracetic acid needs Aflas. Installing EPDM where the chart specifies Viton or Aflas leads to gasket failure at the fittings, not a wall failure. Equally important: do not assume the resin. Because this tank's resin is recorded as HDLPE with an open question, verify HDLPE versus XLPE for your chemical before you order, and confirm the top fitting layout matches your vent, fill, and drain plan using our fitting placement strategy guide, set your level-sensing approach with our level gauge selection guide, and handle labeling with our label and signage compliance guide.
