Pipeline Condition Detecting Apparatus And Method

摘要

This invention relates to an apparatus and method for detecting the condition of a pipeline wall and analysis and estimate of the life of the pipeline by using an apparatus mounted externally of the pipeline and provided to be moved about and/or along at least a portion of the same. The apparatus includes at least one sensor array which includes a plurality of sensors axially offset to provide data for analysis and identification of pipeline defects.

主权项

1. Apparatus for the analysis of the condition of at least part of a pipeline wall, said apparatus mountable on the external surface of the pipeline, said apparatus comprising:
a body, means for inducing a magnetic flux into, and at least partially through, the wall of the pipeline adjacent the location of the apparatus and processing means for providing data relating to the magnetic flux and said processing mean includes at least one sensor array including three sensors configured in a tri-axial sensor array to detect variation in magnetic flux in at least three axes with regard to the wall of the pipeline in order to provide data representative of the condition of the wall of the pipeline.
