Abstract
PURPOSE: To simply, effectively prevent the interstitial corrosion between the heating tube and the tube and the tube plate, by covering the outer surface of the heating tube with the material of carbon steel group, etc.
CONSTITUTION: Such materials 5a, 5b, with the superior interstitial corrosion property, as the carbon steel group, or the ferrite stainless steel, etc., are metallurgically welded so as to cover the outer surface of the heating tubes 1a, 1b, for use of various heat exchangers. This covering is installed at least in the fitting part between the heating tube and the tube plate. According to this method, any gap can not be formed between the outer surface of the barefaced heating tubes 1a, 1b, and the wall of the tube hole in the tube plate, so that the damage of the barefaced heating tubes 1a, 1b, depending on the iterstitial corrosion, can be prevented
