Threaded connection comprising at least one threaded element with an end lip for a metal tube

A ready-to-use threaded tubular connection comprising:

• a female threaded portion at an end of a first tubular component and a male threaded portion at an end of a second tubular component,
• the female threaded portion comprising a female thread, at least one female sealing surface on its inner peripheral surface, and at least one female axial abutment surface,
• the male threaded portion comprising a male thread, at least one male sealing surface on its outer peripheral surface, at least one male axial abutment surface, and a lip provided between the male thread and an axial abutment surface located at a free end of the threaded portion which is distant from the thread, the male sealing surface being located on the lip close to the thread,
• the male thread being made up into the female thread such that the male axial abutment surface and the female axial abutment surface be in contact with the female axial abutment surface,
• the male sealing surface being in interference contact with the corresponding female sealing surface,
• a distal portion of the lip between the male sealing surface and the male axial abutment surface being radially distant from a corresponding surface of the other threaded portion,
• wherein at least one leak channel is provided in one of the male or female threaded portions to place the chamber formed between the distal portion of the lip and the corresponding surface of the other threaded portion, in communication with the interior of the connection.
