Abstract

PURPOSE: To prevent the weld crack and to enable to weld whole materials, by forming weld joint part at the bottom reaming the hole in J type groove shape on the water room side of tube hole on the tube plate and welding the tip end of the tube and joint part after inserting the tube from the drum side.
CONSTITUTION: The J type groove-shaped hole 14 concentrically connecting with the tube hole 12 opening to the drum 11 side of the tube plate 10 and having weld joint part at the bottom opening to the water room 13 side. Next, the tube 15 is inserted from the drum 11 side and the insert ring 18 is attached on the weld joint part and the tube tip end 15A. Hereby, crevice corrosion is prevented and also, welding inspection is made easy by inserting the TIG welding torch 16 from the hole 14 and carrying out welding.
