Replaceable Tank Lining

Abstract

Replaceable tank (RT) for installing in metallic storage tanks for fluids consists of a tank body and one or more orificial members. The RT conforms with inner walls of the storage tank and is made of flexible materials, such as rubber or PVC that are impermeable to the fluids stored. Orificial members having a tubular neck and conforming with the lumen of the orifices of the storage tank are typically made of the same material as the RT. Magnets, attached to, or embedded in, the walls of the RT are attracted to the walls of the metallic storage tank. A method for manufacturing, packaging and for in situ installing an RT is provided.

1 . A replaceable tank (RT) for installing in a metallic storage tank for fluids, comprising:
 a tank body made of a flexible material impermeable to said fluids;   at least one orificial member attachable to a hole in said tank body, and   at least one magnet attached to said tank body for attracting to said metallic storage tank.   
     
     
         2 . A RT for installing in a storage tank for fluids as in  claims 1 , wherein one end of a tubular neck of said at least one orificial member has an external ridge. 
     
     
         3 . A RT for installing in a metallic storage tank for fluids as in  claim 1 , wherein said at least one orificial member is attached to said tank body. 
     
     
         4 . A RT for installing in a metallic storage tank for fluids as in  claim 1 , wherein one end of a tubular neck of said at least one orificial member has a flange. 
     
     
         5 . A RT for installing in a metallic storage tank for fluids as in  claim 1 , wherein said at least one orificial member is rigid. 
     
     
         6 . A method for preventing leakage from metal storage tanks comprising providing an internal lining to said storage tank by magnetically attaching a replaceable tank (RT) conforming to the internal contours of the metal tank. 
     
     
         7 . A method for preventing leakage from metal storage tanks as in  claim 6 , wherein at least one orificial member is further attached to said RT. 
     
     
         8 . A method for preventing leakage from metal storage tanks as in  claim 6 , further comprising
 folding said RT prior to shipping to the place of installation, and   packaging said folded RT in a package insertable into said storage tank through an orifice of said storage tank.   
     
     
         9 . A method for preventing leakage from metal storage tanks as in  claim 6 , wherein gas pressurizing is used for providing said lining,
