DISPOSITIF ET PROCEDE D'ECHANTILLONNAGE DE TUBES POUR UN DIAGNOSTIC DE DEFAUTS ET DE PROPRIETES PHYSIQUES DE CES TUBES ET DE LEUR ENVIRONNEMENT.

摘要

A robotic sampling device (32) for cutting part of a tube wall (12) for sampling, containing a cutting head (36), a retrieval assembly (38) and a drive mechanism (40), is used to cut a window or hole (60) in the tube wall (12) and retrieve the tube wall sample (56), where the sample can be mounted onto a separate tube for testing the physical properties of the cut wall portion, and where a video probe (62) and the like can be passed through the window (60) to monitor conditions near the support plates (14) and tube sheets (16).
