PROBLEM TO BE SOLVED: To prevent the electrification in a pipe by electrically conducting a part consisting of a conductive plastic resin in the longitudinal direction of the pipe. SOLUTION: The half of the section of the pipe is formed of the conductive plastic resin 1 and the remaining half is formed of the transparent plastic resin 2. These parts are so formed as to have the same section in the longitudinal direction. The conductive plastic resin 1 is otherwise disposed at two points of the pipe section and the rest is formed of the transparent plastic resin 2 so that the same section is attained in the longitudinal direction. The most parts are otherwise formed of the conductive plastic resin 1 and are provided with window-like parts consisting of the transparent plastic resin 2 at specified internals. Part of the section is otherwise provided with the part 1 consisting of the conductive plastic resin continuous in the longitudinal direction and the rest is formed of the transparent plastic resin 2. A conductor, such as bare copper wire, is wound around the part of the conductive plastic resin at the terminal or suitable point of the pipe and is grounded. |
