Conductor and Casing Connectors
Liberty’s RunSafe [RS] conductor and casing connectors are weld-on type connector to API 5L line pipe. Depending on the application, the connector can be driven or run as casing connector.
The connectors combines features of the main stream connections such as weld-on and flush ID/OD connections, thus quick make-up by multi-start threads, and semi flush in the OD / ID sizes. The latter allow using one type connector for exploration (free standing) as well as platform applications. The dimensions are such that the connector fits thru the platform guide funnels but still allows make-up with standard elevators. The full pipe body weight can be set on the connection without a requirement for compensators e.d. The ¾ turn make-up only requires manual (belt) tongs.
The thread form eliminates overtorque and for the driveable connectors, a simple but effective anti-rotation device is used to maintain the connection during driving of the conductor.
