A joint comprising a main seal (9), a secondary seal (15) and an external pressure test port (19) providing access to a cavity (17) between the main seal (9) and the secondary seal (15) wherein the integrity of the main seal (9) can be tested in its in-service direction by applying pressure to the cavity (17) via the pressure test port (19) such that the cavity is pressurised and the main seal (9) is tested. Following testing of the main seal (9), the secondary seal (15) may become redundant during normal use of the joint. In some embodiments, however, the integrity of the main seal (9) can be retested at any time due to the reusability of the secondary seal (15).
La présente invention concerne un raccord comportant un joint d'étanchéité principal (9) et un joint d'étanchéité auxiliaire (15) ainsi qu'un orifice extérieur de test de pression (19) donnant accès à une cavité (17) entre le joint d'étanchéité principal (9) et le joint d'étanchéité auxiliaire (15), ce qui permet de tester l'intégrité du joint d'étanchéité principal dans son sens de service en appliquant une certaine pression dans la cavité (17) par l'intermédiaire de l'orifice de test de pression (19) de sorte que la cavité sous pression permet de tester le joint d'étanchéité principal (9). Après le test du joint d'étanchéité principal (9), le joint d'étanchéité secondaire (15) assure une redondance pendant l'utilisation normale du raccord. Toutefois, selon certains modes de réalisation, on peut à tout moment retester le joint d'étanchéité principal (9) car le joint d'étanchéité auxiliaire (15) est réutilisable.
