Patent ID: 7699355

Claim:
Variable-angle tubular connection comprising: a first tubular section ( 4 ) which defines a first central axis (X-X) and which comprises a flange ring ( 10 ) oblique to the first central axis (X-X), a second tubular section ( 6 ) which defines a second central axis (Y-Y) and which comprises an end flange ( 12 ) oblique to the second central axis (Y-Y), the flange ring ( 10 ) and the end flange ( 12 ) forming an axis of rotation (Z-Z), and also clamping means ( 8 ) of the flange ring against the end flange ( 12 ) which are suitable for allowing a relative rotation of the flange ring ( 10 ) and the end flange ( 12 ) of 360° about the axis of rotation (Z-Z), characterised in that at least one of the tubular sections ( 4 , 6 ) comprises a free end ( 44 , 46 ) equipped with at least a first series of pins ( 48 ) projecting radially outwards in relation to the central axis of this tubular section, said tubular section ( 4 , 6 ) comprising a removable flange ( 52 ) which is equipped with a passage recess ( 54 ) for each of the pins ( 48 ) of the first series of pins and which is designed for assembly of the connection ( 2 ) with an adjacent tubing element ( 58 , 62 ) by a mechanical-type junction or by a flange junction, and in that said removable flange ( 52 ) can pivot within an angular range delimited by two first successive pins ( 48 ), wherein the passage recesses ( 54 ) are open radially inwards relative to an axis (A-A) of rotation of the flange ( 52 ), the passage recesses ( 54 ) being adapted to be traversed by the first series of pins ( 48 ).
