Abstract:To this day there is still ongoing controversy about whether to expand first or weld first the tube to tube-sheet joint in heat exchangers. This paper presents a detailed analysis of the advantages. defects and application of the two manufacturing methods, puts forward the main princple in deciding its sequence, and some valuable conclusions are drawn from that.
Keywords:Heat exchanger  Tube to tube-sheet  Expanding  Welding  Expanding and welding joint
