<p>The invention provides a novel joint for pipes used in very low temperature service. The pipe joint comprises a tubular sealing cylinder extending into both pipe ends to be joined and being an interference fit at the distal portions with the inside of the pipe ends. The tubular sealing cylinder is flexible at its ends and is pressed radially outward, in use, by the pressure of fluid within the pipe ends thus effecting a seal.</p> |
