PROBLEM TO BE SOLVED: To enable sampling of clads sticking to the inner face of a pipe easily, safely and reliably by equipping an inserting tip of a rod body which is inserted into and removed from a guide pipe, so that it can rotate freely with a sampling brush and a rotary handle for rotating the rod body. SOLUTION: In a clad sampler, a rod body 2 is placed in a guide pipe 1, both ends of which are open, so that the rod body 2 can be freely inserted and removed. An approximately cylindrical sampling brush 3 is mounted at one end on the inserting side of the rod body 2 and a hook-shaped rotary handle 4 is integrally installed at the other end. A flange 5 is integrally formed at an end on the side of the handle 4 and is installed on a flange on the side of a branch pipe of piping with a bolt and the like, so that the end of the pipe 1 can face the inner face of the piping. In the rod body 2, a bearing 6 is installed on an opening on the side of the handle 4 of the pipe 1 in such a manner that it can be mounted and removed freely, which makes it possible to locate the rod body 2 at an end of the pipe 1 so that it can rotate freely. |
