    摘要： The invention discloses an NDT device for pipeline, belonging to the field of NDT, including a mobile carrier, which moves with fluid in pipeline or is moved by an actuator; a probe testing assembly, which includes a testing component installed on the mobile carrier and having a testing element in which testing probe is encapsulated; a data processing unit, a first signal conditioning unit and a second signal conditioning unit, wherein the testing probe includes an excitation coil, a receiving coil and a passive resonance coil between the excitation coil and the receiving coil. For the invention, no more magnetizing treatment device is needed for testing, so that the system volume is greatly reduced, thereby reducing the requirement of the testing system of the invention on the internal cleanliness of a pipeline, improving flexibility of equipment in the pipeline of the testing system, and greatly reducing the system cost.

    摘要： A re-settable pipeline gauging tool (10) of this disclosure includes a cylindrical tool body (11) that includes a deformable portion (13) with a plurality of sensors (25) located near or on an external circumferential surface (12) of the deformable portion. A sealed unit (60) contains a corresponding signal source (25). Pipeline gauging relies upon the compressibility and elasticity inherent in the deformable portion as it encounters anomalies in pipeline geometry and moves between a first size and a second size, the signal strength of the source detected by the sensors changing as a result. The sensors may be arrayed in a circumferential band (47) about the deformable portion or along its length. In some embodiments, the sensors and source are magnetic or acoustic (e.g., transceivers or radar integrated chips). In other embodiments, the sensors and source are light or fiber optic.

    摘要： There is presented a cable management apparatus for deployment within a pipe, where the pipe houses at least a portion of an umbilical cable. The cable management apparatus comprises a first engagement portion for engaging with an interior surface of the pipe, a second engagement portion for engaging with the umbilical cable, a first end and a second end. The cable management apparatus is configured such that, in use, the umbilical cable extends outwardly and away along the pipe, in substantially opposite directions from the first and second ends. The cable management apparatus is further configured to assist the moving of the umbilical cable along a lengthwise portion of the pipe using at least the first engagement portion and/or the second engagement portion.

    摘要： A sewer inspection or maintenance system is provided, at least comprising a carrier system, a satellite system which is movable relative to the carrier system, and a guide device coupled to the carrier system, along which the satellite system can be guided during a movement relative to the carrier system. The guide device can be extended or unfolded or rolled out from a stowed position into at least one position of use, so that the effective length of the guide device can be increased.
