ABSTRACT:
A method and apparatus is provided for removing the severed end-portions of boiler tubes installed and retained in a boiler header without consequential boiler header metal damage and in a manner whereby a compression gap of uniform width is machined throughout the length and thickness of each retained boiler tube end-portion selected for removal, the machined boiler tube end-portion is subsequently compressed to significantly close the machined compression gap and reduce the tube end cross-sectional circumference, and the compressed tube end is withdrawn longitudinally from engagement with the boiler header tube-mounting bore.
