As a kind of improvement of the utility model, the outer tube sleeve and the upper pipe end-cap, lower pipe end-cap pass through screw thread It links together.
As a kind of improvement of the utility model, the traveller is stretched out from the upper pipe end-cap, lower pipe end-cap, the traveller End is also connected with baffle.
As a kind of improvement of the utility model, circumferential direction of the traveller on the outside of inner tube is angularly uniformly arranged.
The beneficial effects of the utility model are:
1, the flexible coupling of a kind of Offshore Drilling Riser described in the utility model, will by the connector that can be slided relatively Marine riser links together, and the opposite sliding of the limitation inner tube of the traveller by being arranged with spring, thus between marine riser Vibration play buffer function.
2, baffle is set in the end of traveller, baffle main function is to prevent inner tube from completely falling off from outer tube outer tube.
