The Snyder Industries 3000 Gallon XLPE Heavy Duty Cone Bottom Tank is built for full-drain chemical batching where you cannot leave sediment or product sitting in the bottom of the vessel. Molded in crosslinked linear polyethylene (XLPE) in natural white, it carries a 1.9 specific gravity rating and holds 3,000 gallons. The cone geometry stands 120 inches tall on a 95 x 95 inch footprint, so plan your stand pad, clearance, and overhead access before it arrives. The technical drawing on this page shows fitting placement and dimensional detail.
Will it handle your contents?
The 1.9 SG rating is the number that matters for a chem-service cone bottom, and it is the heaviest-duty rating in this cone-bottom class - there is no higher-density step-up to size to, so this body is the top of the range. Full of water this tank weighs about 25,020 lb, and at its maximum rated content density it carries roughly 47,538 lb of contents - confirm your stand, anchoring, and cone-support structure are sized for that load, not just the water figure. The crosslinked resin gives this vessel a tougher chemical and impact tolerance than standard HDPE; if you are weighing the two for an aggressive chemistry, read Snyder XLPE vs HDPE: when crosslinking matters. The drawing shows three connection points to plan your plumbing around: a flange for the process connection, an 18-inch PE threaded/vented fitting for fill and vent, and a manway with 15-inch access as the only service opening. A cone bottom must be supported in a matching stand - see the cone bottom tank stand compatibility matrix and the 3000 gallon cone bottom buyer's guide, then size your draw-down with the Tank Sizing Calculator and Tank Sizing Guide.
Chemical compatibility
This is an XLPE tank rated to 1.9 specific gravity, which makes it a fit for many dense and aggressive solutions. Compatibility is always concentration- and temperature-specific, so verify your exact chemistry against the OEM chemical-resistance chart before service. Build your fitting and gasket package to match the chemical, not the tank wall - the default package here is a PVC fitting with an EPDM gasket, but several chemistries break that default. Verified-compatible chemistries on this XLPE / 1.9 SG body include:
- 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 (verified compatible; no dedicated page yet)

The mistake to avoid
The single most common error on a cone-bottom chem tank is matching the fitting and gasket to the tank wall instead of to the chemical. The XLPE shell tolerates a wide range of chemistries, but a PVC nipple or the wrong elastomer gasket can fail long before the tank does. The default package here is PVC fitting plus EPDM gasket - watch the three exceptions in the list above: hydrofluosilicic acid needs a Viton gasket, DEF needs 316 stainless fittings, and propylene glycol needs PP or 316 stainless (acetic acid and urea also run PP/PVC rather than plain PVC). Confirm your resin assumption too: this is crosslinked (XLPE), which is not field-weldable or repairable the way some HDPE vessels are, so design your plumbing as bolt-on and serviced through the 15-inch manway access. Every fitting and gasket in your package has to land on the three drawing connections - the flange, the 18-inch threaded/vented fitting, and the manway.
