Abstract
The connector comprises a male flange 15 and a female flange 14 allowing to assemble a main tube and auxiliary line tubes 11. A locking collar 17 and a locking ring 40 assemble the male flange and the female flange. Locking collar 17 is mounted mobile in rotation on the outer surface of the male flange while cooperating with the outer surfaces of the male and female flanges. Locking ring 40 is mounted mobile in rotation on the male element of the connector while cooperating with the inner surface of the female connector.
Claims18
A connector for assembling two riser pipe sections for offshore well drilling operations, comprising a first main tube element having as an extension a male connector element provided with a male flange pierced by at least one orifice wherein a first auxiliary tube element is secured, and a second main tube element having as an extension a female connector element provided with a female flange pierced by at least one other orifice wherein a second auxiliary tube element is secured, the male connector element fitting into the female connector element so as to connect the two main tube elements and the two auxiliary tube elements, characterized in that the connector comprises a locking collar and a locking ring, the locking collar being mounted mobile in rotation on an outer surface of the male flange, the locking collar cooperating with the outer surface of the male flange and an outer surface of the female flange for assembling the male flange and the female flange, the locking ring being mounted mobile in rotation on the male connector element, the locking ring cooperating with an inner surface of the female connector for assembling the male connector and the female connector.
A connector for assembling two riser pipe sections for offshore well drilling operations, comprising:
- a first main tube element having as an extension a male connector element provided with a male flange pierced by at least one orifice wherein a first auxiliary tube element is secured,
- a second main tube element having as an extension a female connector element provided with a female flange pierced by at least one other orifice wherein a second auxiliary tube element is secured, the male connector element being configured to fit into the female connector element so as to connect the two main tube elements and the two auxiliary tube elements,
- a locking collar and a locking ring, the locking collar being movably mounted around an outer surface of the male flange, the locking collar being configured for mobile rotation around the outer surface of the male flange, the locking collar being configured to assemble the male flange and the female flange by cooperating with the outer surface of the male flange and an outer surface of the female flange, the locking ring being movably mounted around the male connector element, the locking ring being configured for mobile rotation around the male connector element, the locking ring being configured to assemble the male connector and the female connector by cooperating with an inner surface of the female connector.
