Environment-Assisted Corrosion Cracking in Carbon Steels Utilizing Advanced Ultrasonic Techniques

摘要

Integrity inspection and reliability prediction of critical oil and gas assets are a high priority for oil and gas operators. Of the possible degradation problems affecting oil and gas operating facilities, corrosion, hydrogen and stress-related corrosion and cracking in steels are among the most serious. As a result of the severity of these inspection challenges and the major failures they can cause, there has long been motivation to develop advanced NDT techniques for related defect and crack detection. This paper will cover the latest understanding of damage mechanisms leading to environment corrosion cracking in Carbon Steels and will follow descriptions of advanced nondestructive testing techniques used to detect these damage.
