Manufacturing methods and tube support plate assembly equipment of steam generator

摘要

PROBLEM TO BE SOLVED: To place tube support plates at correct positions.;SOLUTION: This method of manufacturing a steam generator for which the tube support plates 6 having multiple heat-conducting tube insertion holes through which multiple heat-conducting tubes are inserted and supported, are arranged in a cylindrical body part 2, includes a step of arranging one of ends of linear members 20 with respect to multiple tube holes 4a in a tube plate 4 secured at one end of the horizontal body part 2, and arranging the other end of each of the linear members 20 at the other end of the body part 2, a step of positioning the linear members 20 with respect to centers of the tube holes 4a and centers of heat-conducting tubes inserted into the tube holes 4a, and a step of inserting each linear member 20 into a prescribed heat-conducting tube insertion hole of the tube support plate 6, and adjusting an attachment position of the tube support plate 6 to align each linear member 20 with the center position of each heat-conducting tube insertion hole.;COPYRIGHT: (C)2012,JPO&INPIT
