PURPOSE:To raise reliability for installing a sensor to a pipe wall by covering the sensor which is made to adhere tightly to the pipe wall, with a metallic band, and welding said band. CONSTITUTION:A sensor 2 is made to adhere tightly to a pipe 1 and placed. A metallic band 3 is wound to the pipe 1 so as to cover this sensor 2. Subsequently, each band 3 is welded and fixed at one end part. When the sensor 2 is installed in this way, the band 3 and the pipe 1 are not welded, therefore, even if there is a difference in the thermal expansion of the band 3 and the pipe 1, no crack is generated. Also, no welding failure of each bend 3 is generated. In this way, the reliability for installing the sensor to the pipe wall can be raised. |
