Threaded connection for branching a sensor to a double-walled pipe

摘要

The present invention refers to a threaded connection (1) for double-walled pipes, comprising an outer pipe (3), an inner pipe (2) comprising an outward projection (4) having a threaded conical end (5), a component connector (8) having a threaded conical end (7) threaded with the outward projection (4) threaded conical end (5) to provide a first threaded connection, the connector (8) having an annular groove (9) and a sealing ring (10). The threaded connection (1) additionally comprises an intermediate piece (11) with an inner threaded surface (13) threaded with an outward projection (4) outer threaded surface (14) to provide a second threaded connection configured to turn in opposite direction with respect to the first threaded connection, the intermediate piece (11) also having a pressing surface (16) that presses the sealing ring (10) against the connector (8), and a sliding joint (12) engaged with an outer pipe (3) outward projection (20).
