ABSTRACT:
This invention relates to a bore plug and to a bore plugging method, usually but not necessarily for tubes, and has particular (but not exclusive) application for the isolation of defective heat exchanger tubes. The bore plug comprises a sealing member and a holding member, the sealing member being adapted to span the bore, the sealing member having a longitudinal axis and an axial opening to receive the holding member, the holding member being insertable into the opening solely by axial movement. The method includes the steps of {i} pushing the sealing member axially into the bore, and {ii} pushing a holding member axially into the opening so as to urge part of the sealing member into sealing engagement with an inner surface of the bore.
