The Snyder Industries 4100 Gallon XLPE Heavy Duty Cone Bottom Tank is a black crosslinked linear polyethylene (XLPE) tank built for heavy chemical duty, carrying a 1.9 specific gravity rating - high enough to hold dense liquids that thin-wall water tanks cannot. It holds 4,100 gallons, stands 197 inches tall, and sits on a 90 x 90 inch footprint. The full cone-bottom geometry drains completely, which matters for batching, dosing, and clean-out between chemistries.
Will it work for your application
The 1.9 SG rating is the number to plan around. Filled with plain water this cone bottom tank carries roughly 34,194 pounds; at its maximum rated contents it is built to handle about 64,969 pounds. Divide those out and the envelope confirms the rating - about 1.9 times the weight of water - so you can run liquids up to roughly 1.9x as dense as water without exceeding the wall and support design. A 50% ferric chloride load, near 1.5 SG, sits comfortably inside that envelope. One thing a careful engineer will catch: at 197 inches tall on a 90 x 90 inch footprint, this is a tall, narrow profile that has to sit elevated in a stand, so it is sensitive to off-center loading, wind, and seismic forces. Size and anchor the stand to the loaded 64,969 pounds, not just to bear the empty shell. Use the Tank Sizing Calculator and Tank Sizing Guide to check capacity and weight against your pad, and the Cone Bottom Tank Stand Compatibility Matrix to pair a Norwesco, Snyder, or Enduraplas stand.
Chemical compatibility
This is a crosslinked polyethylene (XLPE) tank rated to 1.9 specific gravity. XLPE resists stress cracking and aggressive oxidizers better than standard HDPE - the difference is covered in Snyder XLPE vs HDPE: When Crosslinking Matters. Always verify your specific chemical, concentration, and temperature against the Snyder OEM chemical-resistance chart before service, since compatibility is concentration- and temperature-specific. Confirmed-compatible chemistries for this resin and SG rating include acetic acid (60%), aluminum sulfate 50%, calcium chloride 40%, DEF 32.5% (diesel exhaust fluid), ethylene glycol 100%, ferric chloride 50%, ferric sulfate 60%, ferrous sulfate 20%, hydrofluosilicic acid 26%, magnesium chloride 30%, polyaluminum chloride, potassium carbonate 50%, potassium hydroxide (saturated), propylene glycol, sodium carbonate 30%, sodium thiosulfate 40%, urea solution 50%, and ozonated water up to 10 PPM.
Fitting and gasket pairing
The tank resin is only half the build - your fittings and gaskets have to match the chemistry too. Most of the chemistries above pair with PVC fittings on EPDM gaskets, but three call for deviations from that default, and these are where most chemical cone tanks are spec'd wrong:
- Hydrofluosilicic acid 26% - PP/PVC fitting with a Viton gasket, not EPDM.
- DEF 32.5% - 316 stainless steel fitting, not PVC, on an EPDM gasket.
- Propylene glycol - PP or 316SS fitting.
Acetic acid and urea solution also step up to PP/PVC fittings. The most common mistake is matching the resin to the chemical but leaving a default EPDM gasket where Viton is required, or a PVC fitting where stainless belongs - check each fitting and gasket against the Chemical Compatibility Database for your exact chemical and concentration. If you are spec'ing instrumentation, the level gauge selection guide for chemical service covers radar, ultrasonic, hydrostatic, and magnetostrictive options, and the Snyder Captor Plus 110% containment comparison covers secondary containment for SPCC duty.
