1600 Gallon 30 Degree HDLPE Cone Bottom Tank with Black Poly Stand and No Fitting

The Norwesco 1600 Gallon 30 Degree Cone Bottom Tank (SKU 40814) is a closed-top HDLPE cone-bottom vessel that drains completely through its 30-degree cone, built for batching, mixing, and full-discharge chemical service. It seats on a black poly stand, carries a 1.9 specific gravity rating, and ships with no fitting installed so you spec the outlet and bulkhead to match your chemical. Empty weight is 524 lb; the tank stands 96" tall on an 89" diameter footprint with a 16" lid for filling and access. Maximum contents temperature is rated to 120 F / 48 C.

Will it hold what you're running?

The 1.9 SG rating is the number that matters. It means the tank wall is engineered to carry a liquid up to 1.9 times the weight of water. Filled with water this cone bottom carries 13,344 lb; at its full 1.9 SG rating the contents can weigh up to 25,354 lb. Confirm your fluid's specific gravity before you buy - if your chemical is denser than 1.9 SG, this tank is not rated for it. Use the Tank Sizing Calculator and Tank Sizing Guide to match capacity and weight to your process, and see the technical drawing on this page for the cone angle and stand geometry. With 25,354 lb of possible contents sitting high on an 89" footprint, set the poly stand on a level, load-rated concrete pad and anchor per your site - a loaded cone-on-stand is top-heavy by design.

Chemical compatibility

This is an HDLPE tank rated to 1.9 SG, referenced against the Snyder Industries OEM chemical resistance chart. The resin is listed as HDLPE with a query flag, and the color is unspecified - confirm HDLPE vs XLPE and the tank color with us before you commit it to chemical service, because the two resins behave differently against some oxidizers and color affects UV and FDA status. The listed "FDA Approved" certification is resin- and color-specific, so verify it against the confirmed resin for your application. Compatibility is always concentration- and temperature-specific: verify your exact chemical, concentration, temperature, and the fitting and gasket materials before ordering.

Chemicals this tank's SG rating supports (per the OEM chart) include ethylene glycol (100%, PVC/EPDM), ferric chloride (50%, PVC/EPDM), hydrochloric acid (37%, PVC/Viton), hydrofluoric acid (48%, PP or PVC/Viton), hydrogen peroxide (50%, PVC/Viton), phosphoric acid (85%, PVC/Viton), sodium hypochlorite (under 16.5%, PVC/Viton), sulfuric acid (98%, CPVC/Viton), peracetic acid (30%, 316SS/Aflas), potassium hydroxide (saturated, PVC/EPDM), and sodium thiosulfate (40%, PVC/EPDM). Lower-SG chemicals such as DEF (32.5%) and urea solution (50%) are within range but call for 316 stainless fittings with EPDM gaskets - not PVC - and acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), and sodium carbonate (30%) are also compatible. Match the fitting material - PVC, CPVC, PP, or 316SS - and gasket - EPDM, Viton, or Aflas - to your chemical, and check the full Chemical Compatibility Database. Note the gasket call: chlorine and strong oxidizers want Viton, not EPDM.

The mistake to avoid

Because this tank ships with no fitting, the error we see most is ordering the outlet hardware in the wrong material. A PVC bulkhead on 98% sulfuric, high-concentration hypochlorite, or DEF service will fail even though the HDLPE tank itself is compatible - the chart above lists CPVC, Viton, and 316SS for exactly those cases. Spec the fitting and gasket to the chemical, not to the tank. Second: size a vent through the 16" lid to your fill and discharge rate - critical for fast full-cone drain and for off-gassing services like hydrogen peroxide and sodium hypochlorite.
