EMAT, Pipe Coatings, Corrosion Control And CP Shielding

摘要

EMAT technology will enhance pipeline integrity programs by providing information that has not been attainable previously. This technology will improve the safety and performance of pipelines worldwide. The information obtained from EMAT and ILI gives risk managers direction on where to make repairs or replace pipe that have harmful corrosion or SCC. EMAT technology has brought the pipeline industry into the next phase of critical information that will not only help locate SCC, but more importantly, help companies find and correct CP shielding pipeline coatings before SCC or external corrosion become a problem. By specifying non-shielding to CP pipeline coatings on new projects (plant-applied and girth welds) and requiring the use of non-shielding to CP coating for repairs on existing pipelines with CP, the industry will be protecting its assets, surrounding communities and environment from corrosion and SCC. EMAT technology is a very logical way to provide the future with the safest possible pipeline system.
