    摘要: In a method for heat treatment of an existing pipe constituting a piping system, for converting the residual stress at a welded metallic portion and a welding heat influenced portion of the inside surface of the pipe, into a compressive stress and thereby generate the compressive stress in the inside surface of the existing pipe, a coolant is retained in the pipe; an arbitrary portion of the outside surface of the pipe is heated; thereby a temperature distribution little in temperature difference is produced in the wall surface of the pipe at the heated portion; and then the coolant is allowed to flow. By converting the residual stress at the welded metallic portion and the welding heat influenced portion of the inside surface of the pipe, into the compressive stress, stress corrosion cracking generated from the welded metallic portion and the welding heat influenced portion can be suppressed.

    摘要: There is provided an apparatus for picking up a defective portion replica that can pick up a replica with high accuracy and positively even from a surface of a structure in the water. Within a container part provided at a leading end of a replica pickup part is displaced a deformable member, such as a porous expansion member, which is excellent in adhesion with a replica and which deforms when a replica material is poured into a gap between a surface of a structure and the deformable member. The replica material from the replica material supply nozzle is poured into the gap between the surface of a structure and the porous expansion member and the replica is recovered by making use of adhesion with the porous expansion member.
