CONE-BOTTOM TANK USES
Polyethylene cone-bottom tanks are primarily used for storage, where fast and complete drainage is important. With superior mechanical properties, high stiffness, excellent low temperature impact strength, and outstanding environmental stress crack resistance, they stand up well in tough environments.
Cone-bottom tanks have a high resistance to both physical and chemical attack, making them excellent containment vessels for a wide range of diverse contents, from aggressive corrosive chemicals to food products. They are often used to store a wide range of industrial chemicals, liquid fertilizers, liquid animal feeds, potable water, or liquid food products.
CONE-BOTTOM TANK CONSTRUCTION
The overall general toughness and excellent chemical resistance of polyethylene to a wide array of wet and dry industrial chemicals and food products makes it ideally suited for storage tanks. Dura-Cast cone-bottom tanks are made with FDA-compliant UV-stabilized polyethylene. They comply with U.S. Food & Drug Administration regulation 21CFR 177.1520 (1) 3.1 and 3.2 for storage of potable water, allowing it to be used as a containment article for food products or water.
Cone-bottom tanks can be used indoors or outdoors. Because the resin is UV-stabilized, it will not breakdown under harsh outdoor weather conditions or under prolonged exposure to fluorescent lights. The natural opaqueness of polyethylene permits easy viewing of content levels.
Because cone-bottom tanks are rotomolded, they are of single piece construction, seamless, have consistent tank wall thickness, and are stronger at wall joints and corners. Each cone bottom tank comes equipped with a manway fitting installed on top of the tank.
Cone-bottom tanks are available with Water (1.2 SPG), Standard (1.5 SPG), Heavy (1.9 SPG), and Super (2.5) duty ratings. Standard color is Natural White, but tanks can be ordered in green, gray, black, blue, or your choice of custom color.
Dura-Cast cone-bottom tanks are designed to withstand the tough 24/7 requirements required for today’s demanding use.
