Abstract

PURPOSE: To prevent corrosion and to prolong a life, by forming concavely curved groove on the water room side fringe of tube hole on the tube plate and carrying out welding along the concavely curved part of the groove after inserting the tube projecting a little from the inmost part of the groove.
CONSTITUTION: Larger and deeper concavely curved (J type etc.) groove 13 is formed on the hole fringe of the water room 12 side of the tube hole 11 on the tube plate 10. Next, the tube 14 is inserted in the hole 11 so as the tip end 14A to be rpojected a little from the inmost part 13A of the groove. For example, projecting length is desirable to be about 1/2l1 of the distance between the tube plate face 10A of the water room 12 side and the part 13A. After that, corrosion is prevented and life of instrument is prolonged by welding the end 14A and the groove 13 along curved surface of the groove at the bead forming condition not projecting from the face 10A.
