6000 Gallon 30 Degree HDPE Cone Bottom Tank in White

The 6000 Gallon 30 Degree HDPE Cone Bottom Tank from Snyder Industries is a White, high-density linear polyethylene (HDLPE) vessel built for full-drain chemical service, carrying a 1.9 specific gravity rating that puts it firmly in the heavy-liquid class.Standing 136 inches tall on a 142 x 142 inch footprint, this 30-degree cone tank empties completely through its sloped bottom, which is why processors choose a cone over a flat-bottom or vertical tank for slurries, precipitating solutions, and any liquid you need to evacuate without manual cleanout.It ships from Snyder's Lincoln, Nebraska plant.

Will it work for your application

The 1.9 SG rating is the number that matters here: it tells you the tank wall and support are engineered to hold liquids up to 1.9 times the density of water.Filled with water this tank carries roughly 50,040 lbs, and at its maximum rated content density it is built for up to 95,076 lbs of contents.That headroom is what lets it safely handle dense chemicals like concentrated sulfuric or phosphoric acid where a standard 1.9 SG tank would be under-rated.At 1.9 SG this is already the highest-density rating in Snyder's standard cone line, so there is no heavier-rated cone to step up to - if your liquid exceeds 1.9 SG, this family is not the answer.Factory fittings, shown on the technical drawing on this page, include a flange, a 12" x 13" fitting, an 18" PE threaded/vented fitting, and a manway with 15" access.The 18" vented fitting is the working vent that lets the tank breathe during a 50,040 lb fill or drain and must stay clear; the 15" manway is your entry for the full-drain cone cleanout that justifies buying a cone over a flat-bottom in the first place.Confirm your fill, vent, and outlet plumbing against those locations before you order.Because the 30-degree cone on a 142-inch tank adds real discharge depth below the cylinder, your required stand height is driven by the cone depth - read the discharge centerline height off the drawing and use the Tank Sizing Calculator and the Tank Sizing Guide to confirm capacity and pad geometry for your site.

Chemical compatibility

This is a linear HDPE (HDLPE) tank rated to 1.9 specific gravity - it is not crosslinked (XLPE), and linear PE is the resin behind every per-chemical fitting and gasket recommendation below.Always match the fitting and gasket to the chemical, not just the tank.Per the Snyder chemical-resistance chart - which is concentration- and temperature-specific - this tank handles a broad range of water-treatment and industrial chemicals.The fitting and gasket choice falls into clear tiers: EPDM gaskets cover most salts, glycols, and DEF; Viton is required for the strong oxidizers and concentrated acids; and Aflas is required for peracetic acid only.Stainless (316SS) or CPVC fittings are called out for DEF, peracetic acid, and sulfuric acid.

Viton-gasket chemicals include Sulfuric Acid at 98% (CPVC fittings), Hydrochloric Acid at 37% (PVC), Phosphoric Acid at 85% (PVC), Hydrofluoric Acid at 48% (PP/PVC), Hydrofluosilicic Acid at 26% (PP/PVC), Sodium Hypochlorite below 16.5% (PVC), and Hydrogen Peroxide at 50% (PVC).EPDM-gasket chemicals include Ferric Chloride at 50% (PVC), Aluminum Sulfate at 50% (PVC), Potassium Hydroxide saturated (PVC), Calcium Chloride at 40% (PVC), DEF at 32.5% (316SS fittings), Acetic Acid at 60% (PP/PVC), Ethylene Glycol at 100% (PVC), Ferric Sulfate at 60% (PVC), Ferrous Sulfate at 20% (PVC), Magnesium Chloride at 30% (PVC), Polyaluminum Chloride (PVC), Potassium Carbonate at 50% (PVC), Propylene Glycol (PP/316SS), Sodium Bisulfate (PVC/PP), Sodium Bisulfite (PVC/PP), Sodium Carbonate at 30% (PVC), Sodium Thiosulfate at 40% (PVC), Urea Solution at 50% (PP/PVC), Zinc Orthophosphate (PP/316SS), and Ozonated Water up to 10 PPM (PVC).The lone Aflas case is Peracetic Acid at 30% (316SS fittings).The mistake to avoid is defaulting EPDM everywhere - reach for Viton on the oxidizers and Aflas on peracetic acid.Verify every chemical, concentration, and temperature against the OEM chart and our Chemical Compatibility Database before committing.
