Jacketed <br /> stet dr anenviroentalllsafe <br /> l Tanks <br /> udergstorage tank, Steel , <br /> were developed.They have the strength of steel with <br /> an air tight jacket which provides 3600 secondary <br /> containment and corrosion protection. Both the tank <br /> and the secondary containment jacket carry a U.L. <br /> listing. They are available nationwide in a variety of <br /> standard sizes, with accessories to accommodate -"" <br /> secondary containment of tank fittings, pumps and y =� <br /> associated piping. = - <br /> r Double Wall Design <br /> 2 A Jacketed Steel Tank consists of a secondary <br /> containment jacket, called the Tank Jacket'" which <br /> is applied to a steel underground storage tank at the <br /> factory. This application creates a unique double <br /> s wall tank,with a steel inner wall for structural strength <br /> and a semi-rigid outer wall which has excellent <br /> impact and puncture resistance. The Tank Jacket" <br /> is separated from the steel tank by a special grid to <br /> create the annular space. Each end of the tank has <br /> a monitoring column and access fitting for <br /> installation of a leak detection sensor. <br /> Primary Steel Tank !!I <br /> A U.L. 58, steel underground storage tank has <br /> always been considered the strongest and most <br /> chemically compatible tank you can buy. Fitted with <br /> a Tank Jacket'", it is completely isolated and pro- <br /> tected from corrosion causing chemicals, bacteria <br /> and electrical ground currents which may be n. <br /> present in the surrounding environment On the <br /> inside of the steel tank, striker plates are installed z <br /> under each opening to eliminate internal gauge- ` <br /> stick impact corrosion.We feel so strongly aboutthis <br /> corrosion protection system, we offer a 30 year <br /> warranty against failure, due to corrosion. <br /> Secondary Tank Jacket <br /> A product of years of development and testing, the <br /> Tank JacketT" has proven to be a safe and effective <br /> t 5 means of secondary containment and corrosion <br /> aY <br /> protection for steel tanks. It is made of a thick, 100 <br /> mil., high density polyethylene (HDPE), a dielectric, <br /> non-corrosive and chemically resistant material <br /> which has a proven history of stability in under- <br /> ground applications. It is compatible with petroleum <br /> fuels, methanol, ethanol, as well as many other <br /> chemicals. All Tank Jacket" seams are thermo <br /> welded to provide an air testable container around <br /> the entire steel tank. <br />
