External Slip Type Connector with External Test Port


External Slip Type Connector with External Test Port

The WellEnTech External Slip Type connector with external test port provides a connection at the end of a string of coiled tubing. The robust construction is furnished with standard O-rings, has a large through bore and is easy to attach and remove from the coiled tubing. Available for all sizes of coiled tubing, including taper strings, and can be supplied with any type of threaded connection, shackle hole or winch wire configuration. The external pressure test port provides a means of pressure testing the connector without having to test the entire coiled tubing string. The test port is isolated from the tubing and annulus by two o-rings either side for added peace of mind.

The External Slip Type connector is fitted to dressed coiled tubing. The coiled tubing end should be smoothed off and polished with emery cloth. The bottom sub of the connector is rotated in order to compress the slip into the coiled tubing, a pull test* will confirm engagement and a final make-up of the bottom sub will ensure the connector has a firm hold of the tubing. There are two o-rings, either side of the pressure test port, one primary and the other back up, giving peace of mind for high pressure applications. The connector, when fitted to the coiled tubing, can then be pressure tested using the external test port prior to running in hole.

* Compatible Pull test subs are also available from WellEnTech
