摘要： The present invention relates to a method for easily and repeatedly separating and connecting sections (6a, 6b) of a pipe (6) for a hot and highly pressurised liquid (D) such as a steam pipe. This method uses a dual-wall flanged joint (1) that comprises an outer flange (2) and an inner flange (2) defining a gap (4) in which a cooling fluid (K) flows. The device of the present invention is particularly suited for connecting sections of pipes in a steam turbine (23).
