1100 Gallon 45 Degree Plastic Cone Bottom Tank with Painted Steel Stand

The Enduraplas 1100 Gallon 45 Degree Plastic Cone Bottom Tank pairs a molded polyethylene cone-bottom vessel with a painted steel stand, built for batch mixing and full-drain dispensing where the contents have to empty completely through the cone instead of settling on a flat floor. It holds 1,100 gallons, stands 90 inches tall on a 72 x 72 inch footprint, and carries a single top 16-inch manway for filling, mixing access, and inspection.

Will it work for your application?

The steep 45-degree cone is the reason to choose this tank over a flat-bottom vessel: solids and slurries slide toward the outlet under their own weight, so a batch drains clean instead of leaving residue you have to rinse out. Fully loaded with water the tank carries roughly 9,174 pounds, and because that mass sits 90 inches up on a 72 x 72 inch footprint, this is a tall, top-heavy vessel when full. Confirm your pad is level and rated for the live load plus the weight of your product, and confirm anchoring for outdoor or wind-exposed sites - a cone bottom tank drives its entire load through the stand legs, not across a broad base. If you are still sizing the job, run your batch numbers through the Tank Sizing Calculator and the Tank Sizing Guide so the 1,100-gallon working volume leaves adequate freeboard.

Chemical service - confirm resin and specific gravity first

This listing does not carry a confirmed resin grade or specific-gravity rating, and that is the single most important thing to verify before you put any chemical in this tank. Before ordering for chemical duty, confirm with us whether the vessel is standard HDLPE or cross-linked (XLPE) polyethylene and get the specific-gravity rating in writing, then check your chemical, its concentration, and its temperature against the manufacturer's chemical-resistance chart - a chart reading is concentration- and temperature-specific, not a single yes/no. A tank that handles water at 1.0 specific gravity is not automatically rated for a heavier or more aggressive solution. Cross-reference your chemical in our Chemical Compatibility Database, and match the fitting and gasket materials at the 16-inch manway and any outlet to that same service. Skipping this step is the common, expensive mistake on cone bottom chemical tanks: the stand and cone geometry are right for the job, but resin and gasket selection are what keep it in service.

Fittings and stand

The published drawing data confirms the 16-inch manway on top; see the technical drawing on this page for its placement. The cone outlet size and thread are not part of that published data, so confirm the outlet dimension with us before you order valves, camlocks, or bulkhead fittings. This unit ships with a painted steel stand - if you are weighing a steel frame against a polyethylene stand for your site, our cone bottom tank stand selection decision tree walks through indoor-versus-outdoor exposure, corrosive splash, and load rating. If you want to see how these cone-bottom-with-stand packages come together at other angles and volumes, the 300 gallon 30-degree cone bottom buyer's guide covers the same tank-plus-stand pattern shoppers compare.
