Project description

1. Introduction Industrial pipelines are widely used in petrochemical and power generation industries. During the long-term service, the gaseous or liquid substances transmitted by the pipelines usually erode the interior wall of the pipelines and result in the various defects such as cracks and corrosion pits. Moreover, long-term exposure to air usually results in external pipeline corrosion [1]. These defects endanger the operational safety of the pipelines. In order to avoid the occurrence of the accident, the pipelines should be tested regularly. As a non-contact efficient NDT method…
