<p>The invention relates to a pipe joint, apparatus for sealing and testing a pipe joint, a pipe comprising first and second pipe sections joined together by means of such a pipe joint, and to a method of sealing a joint between two pipe sections and testing the joint. In one embodiment, a pipe joint (26) between first and second pipe sections (22, 24) is disclosed which comprises a female component (28) and at least one male component (30), the first and second pipe sections joined together by locating said male component within the female component. A first seal (32) is provided on one of said male component and the female component and a second seal (34) on one of said male component and the female component. The first and second seals are arranged to provide an interference fit with the other one of said male component and the female component, and are axially spaced apart so that an annular area (38) is defined between the first and second seals, a wall of said male component and a wall of the female component. The joint further comprises an arrangement (40) for communicating with the annular area, so that pressure can be applied to fluid contained within the annular area and the pressure of the fluid in the annular area measured, whereby any reduction in the fluid pressure can be detected, which reduction would be indicative of a leak path existing past at least one of the seals.</p> |
