<p><P>PROBLEM TO BE SOLVED: To provide a flange joint leakage-preventive device surely preventing leakage in a flange joint. <P>SOLUTION: The flange joint leakage-preventive device includes: an elastic leakage preventive member 5 arranged in an abutting position to be abutted along flanges 3'; elastic members 6 arranged along outer peripheries of the flanges 3' in such a manner of fastening the leakage preventive member 5 from both sides thereof in the pipe axial direction; and an attachment member having a recession 7c' composed of an inner bottom surface 7a' opposed to the outer peripheral surfaces 3a' of the flanges 3' and inner wall surfaces 7b' opposed on both sides of the inner bottom surface 7a in the pipe axial direction, and storing the leakage preventive member 5 and the elastic members 6 in the recession 7c', and attached to the flanges 3'. The movement of the leakage preventive member 5 in the pipe axial direction is regulated by the elastic members 6 in the recession 7c' where the leakage preventive member 5 is stored together with the elastic members 6, and the abutting position is maintained. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
