The Snyder Industries 1500 Gallon Vertical Chemical Storage Tank is a 1.9 specific-gravity polyethylene vessel in white, built for aggressive liquids that would degrade a standard 1.0 SG water tank. The 1.9 SG rating is the spec that matters here: Snyder warrants the wall thickness for dense contents, and the tank carries a maximum rated contents weight of 23,769 lb. Plain water fills it to about 12,510 lb, so the gap between those two numbers is your real headroom for dense acids and metal-salt solutions. That is the reason to pay for a 1.9 SG vertical storage tank over a lighter 1.5 SG tank: at 98% sulfuric (SG near 1.84), 50% ferric chloride, or concentrated phosphoric, the 1.9 rating lets you run full without derating fill height. Confirm height, diameter, and fitting locations against the technical drawing on this page before you size a pad or order bulkhead penetrations.
Will it work for your application?
This is a white vertical storage tank, the workhorse HDPE-family format for indoor and outdoor chemical bulk storage where you need volume in a tight floor footprint. Because it is molded in white rather than translucent natural, you lose the sidewall sight-line, so plan for a level gauge from the start; our guide to tank level gauge selection for chemical service walks through radar, ultrasonic, hydrostatic, and magnetostrictive options for opaque tanks. Run your contents weight through the Tank Sizing Calculator and review the Tank Sizing Guide if you are deciding between this 1500-gallon vertical and an adjacent size. Two detailed buyer's guides cover the 1500-gallon vertical format in depth, including the 93 x 60 configuration and the 64 x 116 configuration. If your install requires secondary containment, the Captor Plus 110% containment comparison explains how Snyder's integral containment compares to UL-142 steel under SPCC rules.
Sizing the pad
At full 1.9 SG service the loaded tank approaches its 23,769 lb max-rated contents weight, against roughly 12,510 lb for plain water. Whoever pours your slab needs to engineer for that distributed load across the tank base, not the water figure. If your actual chemical runs below 1.9 SG, you can derate fill height accordingly, but design the pad to the rated maximum. The Tank Sizing Calculator will give you the loaded weight for your specific chemical so you size the foundation once, correctly.
Chemical compatibility
This tank carries a 1.9 specific-gravity rating. The resin designation in our data is unconfirmed, so confirm the resin type (linear HDLPE versus crosslinked XLPE) with Snyder before committing to chemical service - crosslinked resin resists stress-cracking from certain oxidizers that linear polyethylene does not. The tank wall is compatible across the entire list below; the failure point is almost always the fitting and gasket, so match both to the chemical, not just the wall. The following chemicals are listed compatible at the noted concentration, with the recommended fitting and gasket material from the chemical-resistance chart (always verify against the concentration- and temperature-specific chart for your exact service):
- 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 (under 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
Two patterns prevent most field failures. First, the oxidizers - sodium hypochlorite, hydrogen peroxide, hydrochloric and the fluoride acids - require Viton, while the salts and bases run fine on EPDM; the common mistake is reusing an EPDM gasket from a salt service on an oxidizer line, where it will swell and leak. Second, 98% sulfuric acid is the one chemical here that calls for CPVC fittings, not PVC - do not default to PVC bulkheads on concentrated sulfuric just because everything else on the list uses PVC, because PVC is not rated at that concentration. Browse the full Chemical Compatibility Database to confirm your chemical, concentration, and temperature before ordering fittings.
Freight
This tank ships LTL freight, quoted live to your ZIP from the nearest Snyder plant - Lincoln, NE or Philippi, WV. Because it is a tall, full-pallet vertical, freight is real money, so quote it before you commit: use the Freight Cost Estimator for a rate to your delivery address, or call us at 866-418-1777 and we will route it from the closest plant to hold your cost down. The listed price is for the tank only and does not include freight.
