The Snyder Industries 1250 Gallon XLPE Heavy Duty Cone Bottom Tank (SKU 8310000N48) is a bare cone bottom shell built for full-drain chemical service. It molds from crosslinked linear polyethylene (XLPE) rated to a 1.9 specific gravity, the top of Snyder's heavy-duty range, so it carries dense process chemistry that would exceed a standard 1.5-rated tank. The black body measures 95 inches in diameter and 70 inches tall, sits on a 95.0 x 95.0 inch footprint, and gravity-drains to the cone apex for complete evacuation and easy cleanout between batches.
Will it work for your chemical?
Capacity is 1250 gallons. Filled with plain water at SG 1.0 the contents weigh 10,425 lb; at the full 1.9 SG rating the tank is engineered to hold up to 19,808 lb of contents - roughly 27% more weight than a 1250-gallon 1.5-rated tank would carry. That headroom is exactly what dense salt and coagulant solutions need: 50% ferric chloride, 50% aluminum sulfate, 40% calcium chloride and saturated potassium hydroxide all run heavy, and the 1.9 rating gives comfortable margin for them. Confirm your operating chemical's specific gravity before you commit, and size your stand and slab to the 19,808 lb figure when you run dense chemistry. To match this tank to a real fill volume and chemical weight, run the Tank Sizing Calculator and review the Tank Sizing Guide. Note the 70-inch dimension is the tank body alone; on a cone stand the installed height is taller, so check door, gate and ceiling clearance for the 95-inch diameter before delivery, and match a stand rated for the cone apex load - see the Cone Bottom Tank Stand Compatibility Matrix before you order legs or a saddle.
Chemical compatibility
The tank shell is XLPE rated to 1.9 SG. XLPE resists environmental stress cracking better than standard HDPE, which is why Snyder uses it for aggressive duty; read Snyder XLPE vs HDPE: When Crosslinking Matters for where the resin difference actually counts. This tank ships with no pre-installed fittings, so wetted-parts selection is your spec decision - which is precisely why the matrix below matters. Compatibility is for the XLPE shell paired with the listed fitting and gasket materials, drawn from the OEM chemical-resistance chart, which is concentration and temperature specific. Verify your exact concentration and service temperature against that chart, and confirm fitting and gasket material at the hardware, not the shell.
- 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
Watch the exceptions: hydrofluosilicic acid pairs with Viton rather than the EPDM used elsewhere, and DEF and propylene glycol lean on stainless or PP wetted parts. Ozonated water is an oxidizer, so 10 PPM is the listed ceiling - do not assume open-ended ozone service. Match the fitting and gasket material to the chemical you are running, and cross-check the full Chemical Compatibility Database for any chemical not listed here.

Mistake to avoid
The most common error on a tank like this is trusting the wrong fitting hardware. The 1.9 SG XLPE shell handles the chemistry, but a mismatched gasket at the bulkhead or outlet is where failures start - run an EPDM gasket where the chart calls for Viton (as with hydrofluosilicic acid) and the seal degrades. Pick fitting and gasket material by chemical, monitor level with the right instrument for your service, and review Tank Level Gauge Selection for Chemical Service before you spec a gauge.
