The Snyder Industries 1550 Gallon HDPE Vertical Chemical Storage Tank is built for serious chemical duty: a 1.9 specific-gravity rating in high-density linear polyethylene, standing 124 inches tall on a 64 x 64 inch footprint. The 1.9 SG rating is the number that matters here. It means the tank wall is engineered to hold liquids substantially heavier than water, which is exactly what most concentrated chemical solutions are. This Snyder vertical storage tank holds 1550 gallons in a white shell, and it ships without pre-installed chemical fittings, so the connections you add are a deliberate part of your spec.
Will it work for your application
Size your fill against weight, not just gallons. At 1550 gallons of plain water this tank carries roughly 12,927 pounds; loaded to its full 1.9 SG rating the contents can reach about 24,561 pounds. Confirm your pad, slab, and any containment can carry that maximum before you order. The 64 x 64 inch footprint and 124-inch height should be checked against your door openings, ceiling clearance, and any roofed enclosure. For help matching gallons to your actual draw-down and refill cycle, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide. The technical drawing on this page gives you the dimensioned layout for planning fittings, anchoring, and access.
Chemical compatibility
This is an HDLPE (high-density linear polyethylene) tank with a 1.9 specific-gravity rating. The resin handles the tank shell only; because this tank ships bare, the fitting and gasket materials listed below are the parts you must source separately to complete a compatible system, and compatibility is always concentration- and temperature-specific. Verify every chemical against the manufacturer's chemical-resistance chart and our Chemical Compatibility Database at your exact concentration and operating temperature before committing.
Chemicals this tank is rated to store, with the fitting and gasket materials to pair with each:
- Acetic Acid 60% — PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate 50% — PVC fittings, EPDM gaskets
- Calcium Chloride 40% — PVC fittings, EPDM gaskets
- DEF (diesel exhaust fluid) 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
Watch the rows that break the default PVC-plus-EPDM pattern. DEF and peracetic acid call for 316SS fittings and sulfuric acid 98% needs CPVC, not PVC; peracetic acid is also the only chemical here that requires an Aflas gasket. On the gasket side, the strong oxidizers and acids — sulfuric acid, hydrochloric acid, hydrogen peroxide, phosphoric acid, and sodium hypochlorite — call for Viton rather than EPDM. Putting the wrong elastomer on an oxidizer is the single most common chemical-tank mistake, so match the gasket to the chemical, not just the fitting.
Avoid the specific-gravity mistake
The mistake that bites buyers on a tank like this is matching gallons but ignoring specific gravity. A 1.9 SG rating is your ceiling, not a suggestion: if your liquid's specific gravity exceeds 1.9, you need a higher-rated tank, full stop — and 1.9 already sits near the top of the standard chemical-tank SG ladder, so call us at 866-418-1777 to spec the right shell rather than overfilling this one. Equally, confirm the resin is right for your service rather than assuming, and spec your level instrumentation deliberately for corrosive vapor spaces. Our guide on tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options, and if secondary containment is in play, compare your options with our Snyder Captor Plus 110% containment vs UL-142 SPCC breakdown.
This Snyder vertical storage tank ships LTL freight from the nearest of our three plants — Lincoln, NE; Marked Tree, AR; or Philippi, WV — and the live quote pulls from whichever of those is closest to you, so you only pay for the lane you actually use.
