The Snyder Industries 4400 Gallon XLPE Cone Bottom Tank is built for full-drain bulk chemical batching and metering. Molded in black crosslinked linear polyethylene (XLPE) with a 1.5 specific gravity rating, this cone bottom tank stands 200 inches tall on a 90 x 90 inch footprint and self-empties through its sloped bottom so you are not pumping against a flat floor or leaving a heel of product behind. The factory fitting package shown on the technical drawing on this page includes a flange, an 18" PE threaded/vented fitting, and a manway with 15" access for inspection, gauging, and instrument entry.
Will this tank handle your chemical and fittings?
XLPE is the more chemically resistant of the two polyethylene resins Snyder molds, and the 1.5 SG rating means the wall is engineered to hold contents up to 1.5 times the weight of water. The manway with 15" access gives you a real working port for level instruments, sampling, and inspection. Plan your top connections around the flange and the 18" PE threaded/vented fitting on the drawing; the vent is critical on a closed cone bottom tank because fast fill and draw can pull or push enough air to deform a poly wall if the tank cannot breathe. Match valve, bulkhead, and bottom-outlet hardware to the chemical, not just the tank, and confirm wetted fitting and gasket materials per the compatibility notes below.
How heavy does it get, and what does that mean for the pad?
Filled with water this tank weighs about 36,696 lb, and at its full 1.5 SG rating the contents can reach roughly 55,044 lb. That entire load rides on the 90 x 90 inch footprint and the cone, so the tank needs a matched steel stand or a fully engineered ring-and-cone support, never a bare flat slab. Size the stand and the pad to the rated design load of about 55,044 lb, not the 36,696 lb water weight, and run the numbers with our Tank Sizing Calculator and Tank Sizing Guide. For stand selection across brands, the Cone Bottom Tank Stand Compatibility Matrix walks through Norwesco, Snyder, and Enduraplas options.
Chemical compatibility
This is a black XLPE tank rated to 1.5 specific gravity. The chemicals below are within that SG rating for XLPE; always confirm against the OEM chemical-resistance chart, which is concentration- and temperature-specific, before placing anything in service. At 1.5 SG with EPDM gaskets and the noted wetted fitting materials, this tank suits acetic acid (60%, PP/PVC fittings, EPDM), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%), ferrous sulfate (20%, PVC, EPDM), magnesium chloride (30%, PVC, EPDM), sodium carbonate (30%, PVC, EPDM), urea solution (50%, PP/PVC, EPDM), and ozonated water (PVC fittings, EPDM, to a hard maximum of 10 PPM). One spec note for the diesel exhaust fluid crowd: DEF at 32.5% and the matching urea solution call for 316 stainless wetted fittings, not the PVC most of the other chemicals use, so spec your outlet, valve, and bulkhead hardware in 316SS before you plumb it.
Several chemicals are out of range for a 1.5 SG tank and need the heavier 1.9 SG XLPE construction instead: ethylene glycol, ferric chloride, ferric sulfate, hydrofluosilicic acid, polyaluminum chloride, potassium carbonate, potassium hydroxide, propylene glycol, and sodium thiosulfate. Those eight take EPDM gaskets with the single exception of hydrofluosilicic acid, which requires Viton, so do not default to EPDM on that service. If your chemical is on this list, do not order this 1.5 SG unit. For the full picture, work from our Chemical Compatibility Database and pair the right gauge with the level gauge selection guide; bulk poly chemical storage should also be labeled per the NFPA 704 and GHS signage standard.
The mistake to avoid
The single costliest error on a tank this size is matching the chemical to the SG rating but ignoring the resin and fitting-metal question on edge cases. Verify your chemical, its concentration, and its temperature against the OEM chart before service; a chemical that is fine at one concentration can exceed the 1.5 SG rating at another, which is exactly why ethylene glycol and ferric chloride sit on the higher-SG list above. Get the wetted fitting metal right too, since DEF and urea need 316 stainless rather than the PVC that handles most of the standard-list chemicals.
