Method of repairing a tube using a flow through tube plug, methods of repairing and forming a laminated tubesheet, and apparatus having a flow through tube plug

摘要

A method and apparatus for the repair of damaged tubes (18), such as heat exchanger tubes, comprising inserting a flow through plug (28) into the damaged heat exchanger tube. The flow through plug (28) is tapered and creates a press fit when inserted within the heat exchanger tube (18). The flow through plug (28) has an aperture (34) along its axis, thus allowing for flow lengthwise through the flow through plug (28).
