摘要:
A flange (33) which can be connected to a length of pipe which is to be renewed (1a) and which comprises a series of separable disc-shaped elements individually constituted by a plurality of parts. Sealing-tight gaskets are interposed with a clamping effect between two element parts and between two adjacent disc-shaped elements. By way of a terminal flange element (33e) it is possible also to place at the end of the flange a monitoring device or a counter-flange (77) for guiding a casing pipe (35). The flange may be dismantled when casing is completed.
