<P>PROBLEM TO BE SOLVED: To provide a tool for installing a heat transfer tube vibration isolation fitting capable of easily and relatively precisely performing temporarily positioning of a vibration isolation fitting. <P>SOLUTION: A plurality of U-shape heat transfer tubes which are inserted through holes of a tube plate and horizontally arranged are stacked. This tool 10 for installing a heat transfer tube vibration isolation fitting is used when arranging a V-shape vibration isolation fitting between circular arc parts of the heat transfer tubes arranged protruding from the tube plate so that both ends thereof are arranged at a preset position outside from the heat transfer tube that is located at the outermost circumference out of the heat transfer tubes arranged in the same plane. This tool includes a pair of main arms 11 of a length larger than a radius of the circular arc part of the heat transfer tube that is located at the outermost circumference, a connection part 12 rotatably connecting respective front ends of the pair of main arms 11, and an opening angle adjusting means 13 for adjusting an opening angle θ of the pair of main arms formed by opening rear edge sides of the pair of main arms 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
