ABSTRACT:
The present invention relates to a clamping assembly for securing a flexible liner to the inside of a rigid storage tank and to a method therefor. The clamping assembly is adapted to receive a flexible liner between an elastomeric base support and an elastomeric clamp plate, and fastening means are adapted to apply pressure to the system, retaining the flexible liner between the elastomeric base plate and the elastomeric clamp plate. The assembly further comprises at least one filling pipe and/or venting pipe which passes through a mounting plate which is adapted to be attached to the outside of the storage tank. In the method of the invention, a small hole is cut in the top of the liner, through which a rigid base plate and the elastomeric base support are inserted. The pipe is attached to the rigid base plate, and the elastomeric clamp plate and a rigid clamp plate are placed over the pipe on the outside of the liner. A mounting plate having an opening therein for passage of the pipe therethrough is placed over the pipe and is attached to the pipe. The mounting plate is then attached to the outside of the storage tank.
