Polyethylene Cone Bottom Tanks

Avaliable in 30 and 45 degree slopes, sizes range from 15-11,500 gallons For fast and complete drainage of liquids and powders, Kefco's cone bottom bulk poly tanks are offered in a wide variety of sizes and diameters.  All designs are supported by heavy-duty steel stands, with up to 2" schedule 40 tubing construction.	Available with seismic zone 4 and UBC 110 mph wind restraint tie-down systems Most Kefco cone-bottoms incorporate molded-in tie-down lugs, which are designed to interface with a cable tie-down system.  Many poly tank designs have the ability to be modified for even more stringent specification standards when required.
Material options for a diverse range of application requirements Kefco has the ability to cater a poly tank's material construction to an application's specific requirements.  We offer the following resin options: High-density linear polyethylene (HDLPE)* in black & natural white color Cross-linked, high-density polyethylene (XLPE) in black & natural white color Opaque white -- "black-out" resin	Specific gravity rating's are based on the industry's most severe calculation  Kefco utilizes a 600 psi hoop stress measured from the top of the cone poly tanks dome to calculate our posted specific gravity for every vertical poly tank we manufacture.  As a result, Kefco's specific gravity ratings deliver a stronger poly tank with a higher safety factor.  Standard specific gravity choices are 1.5 and 1.9, other ratings are available upon request.  Specific gravity reflects material weight.  For example, 1.5 S.G.=12 lb/gallon, and 1.9 S.G.=15.2 lb/gallon.
* Complies with U.S. Food and Drug Administration Regulation 177.1520.	All poly materials are UV stabilized for long-terrm outdoor service.
