Abstract
A method and apparatus of separating a vessel which is partly welded to a tubesheet of a tube bundle, includes removing the weld seam and reducing the wall thickness of the vessel until only approximately 1/8' of wall thickness remains and thereafter parting the vessel from the tubesheet by extruding the remaining wall thickness using a wheel cutter. The wheel cutter itself comprises a uniform thickness disk having a frusto-conical, cylindrical and subsequent conical portion on its outer periphery, the conical portion tapering to a greater extent that the frusto-conical portion.
