摘要：PROBLEM TO BE SOLVED: To provide a pipe inside lining pig requiring less working processes for lining resulting in more efficient work, without giving damage to a lining agent after applied during collecting the pig. SOLUTION: The pipe inside lining pig comprises a large-diameter pipe pig 1 and a small-diameter pipe pig 2 arranged rearward in the moving direction and frontward in the moving direction, respectively, for applying the lining agent to the inner face of a pipe consisting of a large-diameter pipe A and a small-diameter pipe B. The large-diameter pipe pig 1 and the small-diameter pipe pig 2 are in a mutually integrated structure. At least the large-diameter pig 1 is formed with a hollow body of an elastically deformable soft material. COPYRIGHT: (C)2005,JPO&NCIPI
