14 Development of Portable Facing Machine Tool for Machining of Tube Sheet and Shell of a Heat Exchanger
Download citation file:
Usually in Shell and Tube heat exchangers, at the time of assembly of the Tube bundle assembly, the gasket seating face of the flanges and the gasket seating face of the Tube sheet might get distorted and damaged. Due to this distortion and damage there is a possibility of leakage during hydrotest of the equipment. To correct this distortion and damages, it is necessary to do machining in that area to attain a flat surface with required surface finish. But due to the weight and size of the assemblies it is difficult to move the equipment to the floor boring...
