2. Description of the Related Art Conventionally, this kind of pipe joint repairing method considers a measure for preventing fluid leakage in the pipe from the flange joint portion in a large range, and extends to a part of the pipe before and after the flange joint portion in the longitudinal direction of the fluid conduit. A joint cover was provided to carry out the method. As an example thereof, the joint section cover is divided into two as the joint section cover at a surface including the axis of the fluid conduit, and in a state where each of the divided surfaces and the cover is assembled, a sealing treatment is applied to a surface in contact with the fluid conduit. A part of the fluid conduit to which the flange is attached and the flange joint part are provided in a wrapped form, and the joint part covers are connected to each other by bolts,
There was a pipe joint repair method to prevent fluid leakage.
