DEVICE AND METHOD FOR SECURING CONDUIT INTERIOR WEAR SLEEVE

摘要

A device and method for securing a sleeve (for sacrificial wear and/or electrical isolation) inside a conduit. In one embodiment, the retention device sits adjacent one end of the sleeve and comprises a ring having a protuberance or lip extending parallel to and against the end of the sleeve, thus pressing the end of the sleeve against the inner surface of the conduit. This has the advantage, in situations where fluids are flowing through the conduit, of reducing the risk of fluids moving behind the sleeve and collapsing it inwardly.
