The device detects a chemical environment in the pipeline that is likely to cause corrosion of the pipeline, and comprises sensors 6 mounted on a mobile carrier 5 moveable within the pipeline. The sensors may be electrochemical and the carrier may be a pipeline pig. The sensors are mounted in cavities disposed at the peripheral wall of the carrier, which also contains either a recording device 7 or a device for transmitting data to a location outside the pipeline, so that measurements can be made at locations along the pipeline. The measurements may be of water in oil, and an assessment of the possibility of corrosion can be made. The pig can be propelled by flow of fluid in the pipe, by remote control, or by the application of an external force. |
