The sliding joint is arranged relative to the sensitive assembly so that a radial movement of the sliding joint is restricted and an axial movement of the sliding joint is permitted.
One end of the sliding joint is in communication with the sensitive assembly of the downhole tool and the other end of the sliding joint is in communication with another component of the downhole tool.
When in use, the sliding joint isolates the sensitive assembly from an axial load, thermal stress, or both axial load and thermal stress.
A slip joint driveline (10) adapted for mounting between two universal joints (12, 14) is provided.
A slip joint (35) reduces vertical mechanical shock transmitted through the tubing string (46) to the pump (34) on firing: centralisers (56, 58) minimize whiplash vibration, and lateral shock absorber (60) absorbs radial shock.
One (11c) of the radial direction portions supports the to-be-detected portion (12a) at the to-be-sealed fluid side, and the other radial direction portion (11a) is slidingly sealed by seal lips (14a, 14b, 14c).
The present application is directed to a fluid line assembly comprising a first fluid conveying conduit (12), a second fluid conveying conduit (14), and a slip joint (22).
