Unlike existing slip connectors, the internal slip connector does not rely on grub screws to transmit torque from the tool string through to the coiled tubing. A unique nonrotational slip arrangement provides high bidirectional torque resistance. The slip is positively engaged into the bottom sub via drive teeth, therefore transmitting any rotational torque from the tool string directly to the pipe.
The basic installation to the coiled tubing does not require any specialized tooling or makeup torque. The connector is simply fitted to the pipe and an overpull taken to test and set the connector.
The internal slip connector also has only four main components and includes an enclosed locknut feature to prevent the connector from being jarred free from the pipe.
Both internal and external versions of the slip connector feature an interchangeable service connection sub, allowing the operator to easily change from one thread connection to another.
When ordering an internal slip connector, please specify size, coiled tubing size, coiled tubing wall thickness, and thread connection.
- High tensile strength
- Internal pressure seal
