    Patent number: 6533034
    Abstract: A centralizer for engagement with a pipe exterior surface to be positioned downhole in a wellbore. The centralizer includes a collar which can be fastened with set screws or other connector to the pipe exterior surface. A body is engaged with said collar for containing axial movement of the body within a selected portion of the pipe exterior surface while facilitating rotational movement of the body relative to the pipe exterior surface. The engagement between the collar and the body permits rigid attachment of the collar to the pipe while permitting the centralizer to free-float relative to the pipe.
