CONNECTING DEVICE FOR HORIZONTAL CONNECTION Russian patent published in 2015 - IPC F16L1/26 E21B43/13 

FIELD: construction.

SUBSTANCE: invention relates to the devices for joining and connecting the first and second pipelines, containing the ends (E1, E2) of the first and second pipes at the sea bottom in the place of connection. Connecting device (10) comprises the first connecting part (1), holding the end (E1) of the first pipeline; the second submersible connecting part (2), holding the end (E2) of the second pipeline and connector (3), disposed between the connecting parts (1, 2) for the final connection of ends (E1; E2) of pipes inter se. The guiding device (5) cooperates with the guiding structure (4) during lowering of the second connecting part (2) to the first connecting part (1) and rotates the second connecting part (2) for preliminary alignment of the end (E2) of the second pipeline towards the end (E1) of the first pipeline, so that the first and second pipelines are brought to the alignment with each other at the sea bottom. Auxiliary inclined structure (6) with stop surfaces and guide means cooperates with the second connecting part (2) and facilitates the precise alignment of the ends (E1, E2) of pipes.

EFFECT: improvement of joining and connection.
