Abstract: A lamp assembly comprising one or more lamp clusters. Each lamp cluster comprises one or more electrodeless UV lamps which are excited by microwaves emitted from a microwave generator. The microwave generator and power supply are enclosed within a housing that is integral with the lamp clusters. The lamp clusters are wholly surrounded by a waveguide. The waveguide, comprising a flange and a distal end cap connected by a mesh, forms an enclosure. The waveguide is essentially UV transparent to allow UV light to pass through but effectively opaque to microwaves in order to substantially contain the microwaves within the waveguide enclosure.

Abstract: A system is disclosed to use a rotary milling head to break or cut the bond of a heat transfer fin base to a boiler tube, thereby removing the heat transfer fins from the boiler tube to facilitate the more efficient repair of the boiler tube.

Abstract: A system is disclosed to use a first rotary milling head to break or cut the bond of a heat transfer fin base to a boiler tube, thereby removing the heat transfer fins from the boiler tube, and a second rotary milling head to bevel the exposed end of the boiler tube, thereby facilitating the more efficient repair of the boiler tube.

Abstract: An end prep tool is mounted in substantial alignment with a theoretical center of a pipe and used to prepare an end of a pipe, for example, by boring and/or cutting the end of the pipe. A tool centering and mounting system comprises a clamp cage and a tool mounting member having an inner cylindrical surface. A centering tool is mounted to the tool mounting member and used to adjust the tool mounting member until substantially aligned with the theoretical center of the pipe. The end prep tool comprises a tool feed assembly that moves a cutting tool radially with respect to the axis of rotation and axially according to a predefined cutting profile.
