Sealing flange, in particular for lining the insides of pipelines

摘要

The sealed connector (14) comprises an external tubular body (20) to which is connected annular sealing joints (32a-32d) coaxial with the body axis (22). These joints surround a pipe when it is introduced inside the connector through the joints. An annular part (40) located inside and connected to the tubular body guides and centralises the pipe in the tubular body. There are two annular parts fixed inside the external body towards each of its ends. These annular parts have truncated conical surface (42) located in opposite directions. The external tubular body is terminated from the side by an external collar (26) supported against the piping. A plug (62) hermetically seals the end of the tubular body, to increase the sealing of the system.
