摘要： A tool for intervention on the wall of a fluid pipe, comprising a duct segment through which the fluid is intended to flow when the tool is in the pipe, and at least first and second modules for creating seals between the wall of the pipe and the duct segment, to isolate the fluid circulating in an outer part of a section of the pipe, between the first and second seal creation modules.
The tool includes motorized rollers for moving the tool in the pipe and a module for determining the location of the tool in the pipe.
