Abstract
PURPOSE: To prevent flange deformation due to leakage and corrosion, enabling to detect clearly the range of leakage.
CONSTITUTION: The groove 1 is located at outer side more than 2 bolt hole 2, the length is the same as pitch of hole 2 or slinghtly long, the groove 1 is connected to the pipe 4 through the hole 3 provide to the flange from every groove 1. The pipe 4 is connected to the header 5, the header 5 is connected to ground condenser line 8, a thermemeter 6 is installed the piping between the groove and header 5. By above construction, since the steam leaked from inner surface of the flange 7 is led to header 5 and line 8 through the hole 3 provided to flange 7 and pipe 4 from the groove 1, leakage from every portion is detected with temperature rise with thermemeter 6 provided to every piping 4. As the pressure in the groove 1 is the same as that in the line 8, if the leakage closes to the groove 1, it does pot leak to the outer portion.
