Japanese Patent JP2006519369
Kind Code:
A
Abstract:
The present invention relates to a method and an apparatus for determining the life span for secure use of a pipeline comprising the steps of a) defining an area for surface corrosion analysis on the pipeline, b) providing a corrosion scanning system for scanning the defined area on the pipeline, c) localizing and measuring the corrosion on the surface of the defined area by means of the corrosion scanning system, d) determining the remaining wall-thickness of the pipeline at the defined area by means of the corrosion scanning system, and e) processing the surface condition data related to corrosion at the defined area obtained in steps c) and d) to determine the life span for secure use of the pipeline. In another aspect the present invention relates to a corrosion scanning system for performing for performing the method according to the invention. In another aspect the invention relates to a prediction system for predicting the secure life span of a pipeline.
