DEVICE AND METHOD FOR RETAINING PROBE EXTERIOR WEAR SLEEVE

摘要

A device and method for retaining a sacrificial wear sleeve on the exterior of an in-pipe device such as an electronics package or probe. In one embodiment, the retention mechanism 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 external surface of the device. This has the advantage, in situations where fluids are flowing through the pipe and around the device, of reducing the risk of fluids moving beneath the sleeve and damaging it and/or the underlying device external surface. In another embodiment, the retention mechanism is of unitary construction with the device itself and comprises a protuberance or lip extending parallel to and against the end of the sleeve, thus pressing the end of the sleeve against the external surface of the device.
