Abstract

The invention provides an inspection assembly for insertion inspection of an elongate tubular member. The inspection assembly includes a probe head with a sensor. The assembly also includes a flexible shaft connected to the probe head and transmitting a motive force to the probe head to move the probe head within the elongate tubular member. The probe head includes at least one characteristic to minimize resistance against movement of the probe head along a torturous path within the tubular member.

Description

technical field [0001] The present invention relates to internal inspection probes for inspecting tubular components such as those found in nuclear steam generators. Background technique [0002] The use of inspection / detection devices such as eddy current sensors is known. For example, such devices may be used with nuclear power generator tubular components having meandering bends (eg, u-bends). However, it is possible to know that the device has become stuck, or otherwise unable to travel along the tubular member, making further inspection impossible. Therefore, improvements are required to avoid such problems. Contents of the invention [0003] The following overview presents a brief overview in order to provide a basic understanding of some aspects of the systems and / or methods described herein. This summary is not an extensive overview of the systems and / or methods described herein. It is not intended to identify key / critical elements or to delineate the scope of ...
