The Snyder Industries 10500 Gallon HDPE Vertical Chemical Storage Tank in white is a Lincoln, Nebraska-built bulk storage vessel molded from high density linear polyethylene and rated to a 1.4 specific gravity. It stands 169 inches tall on a 142 x 142 inch square footprint, holding 10,500 gallons. For anyone sourcing a vertical storage tank, hdpe chemical tank, or large Snyder storage tank for a bulk chemical program, that 1.4 SG rating is the number that decides whether it fits your chemistry.
Will it work for your application?
Confirm two things before you commit: weight on the pad and the specific gravity of what you are storing. Filled with water (SG 1.0), this vertical storage tank carries roughly 87,570 pounds of contents; at its maximum rated contents the tank is engineered to hold up to 122,598 pounds, which corresponds to a fluid at the 1.4 SG ceiling. That entire 122,598-pound load concentrates on a single 142 x 142 inch base, so your foundation and ring-wall have to be designed for that bearing pressure across that exact footprint. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your volume and contained weight line up with this vessel before ordering. Dimensions and fitting locations are shown on the technical drawing on this page.
Chemical compatibility
This is an HDLPE tank rated to 1.4 specific gravity. At that rating it suits lighter chemistries, and you should match fitting and gasket material to the chemical. Two chemistries in our chart fall inside its 1.4 SG range:
| Chemical | Concentration | Fitting | Gasket |
|---|---|---|---|
| Diesel exhaust fluid (DEF) | 32.5% | 316SS | EPDM |
| Urea solution | 50% | PP/PVC | EPDM |
Verify every selection against the OEM chemical-resistance chart for your exact concentration and temperature before you specify.
Many heavier and more aggressive chemistries exceed a 1.4 SG tank and need a higher specific-gravity vessel. If you are storing any of these, plan on a different tank tier rather than this one.
Require a 1.5 SG tank: acetic acid (PP/PVC, EPDM), aluminum sulfate (PVC, EPDM), calcium chloride (PVC, EPDM), ferrous sulfate (PVC, EPDM), magnesium chloride (PVC, EPDM), sodium carbonate (PVC, EPDM), and ozonated water (PVC, EPDM).
Require a 1.9 SG tank: ethylene glycol (PVC, EPDM), ferric chloride (PVC, EPDM), ferric sulfate (PVC, EPDM), hydrochloric acid (PVC, Viton), hydrofluoric acid (PP/PVC, Viton), hydrofluosilicic acid (PP/PVC, Viton), hydrogen peroxide (PVC, Viton), peracetic acid (316SS, Aflas), phosphoric acid (PVC, Viton), polyaluminum chloride (PVC, EPDM), potassium carbonate (PVC, EPDM), potassium hydroxide (PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium hypochlorite (PVC, Viton), sodium thiosulfate (PVC, EPDM), sulfuric acid (CPVC, Viton), and zinc orthophosphate (PP/316SS, EPDM).
The SG requirement is concentration- and temperature-dependent, so cross-check your chemistry against the OEM chemical-resistance chart and the Chemical Compatibility Database before you specify.
The mistake to avoid
The expensive error on a tank this size is buying the 1.4 SG version for a chemistry that needs more. Sodium hypochlorite, sulfuric acid and ferric chloride belong in a 1.5 or 1.9 SG tank with the correct fitting and gasket package, not this one. The second is gauging and labeling: size your level instrumentation and your hazard signage to the chemical, not the tank. Our guides on level gauge selection for chemical service, tank label and signage compliance, and chemical sampling protocol walk through getting those right, and the Snyder Captor containment comparison covers secondary containment options.
