The device has an inner tube (1) and an outer tube (2), where the tubes are coaxial and are provided with the same length. A connection (3) is provided with a tubular body (4) that is arranged to tightly surround a portion of a pipe (T) and receive a set of ends (1.1, 2.1) of the tubes. Another connection (12) tightly surrounds the portion of the pipe and cooperates with another set of ends (1.2, 2.2) of the tubes. One of the connections is provided with a drain pipe (8) or a feed pipe (10) of a set of circulation conduits (101, 102) for a coolant i.e. cooled water. An independent claim is also included for a method for installation of a device for circulating a coolant around a pipe for transporting fluid. |
