Abstract
A method and apparatus for the repair of damaged tubes, such as heat exchanger tubes, comprising inserting a flow through plug into the damaged heat exchanger tube. The flow through plug is tapered and creates a press fit when inserted within the heat exchanger tube. The flow through plug has an aperture along its axis, thus allowing for flow lengthwise through the flow through plug.
