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.

A clamping assembly for securing a flexible liner to a storage tank or the like, said assembly being disposed completely within said tank and comprising a plurality of separate liner retaining components; said components comprising upper and lower elastomeric members disposed parallel and opposite to each other, upper and lower rigid support members disposed parallel to and respectively above and below said elastomeric members, and fastening means for holding said assembly together, said liner located between said elastomeric members, said fastening means urging said rigid support members together to retain said liner between said elastomeric members, said lower elastomeric member being generally circular in shape and having a circular recess in the lower surface therof with said lower rigid suport member embedded in said recess, said lower elastomeric member having an outer portion with a taper in a downward and outward direction, said lower rigid support member providing maximum resistance to the bending of said lower elastomeric member at the point where said taper begins and a lesser resistance at the end of said taper, thereby preventing said liner from rupturing or breaking loose from said clamping assembly.
