腐蚀裂纹(CIC)已被确定为在运行管道中的混合缺陷,其中裂纹或裂纹群与大量腐蚀同时发生。最重要的是要开发一个可靠的和一致的方法来评估剩余强度的CIC缺陷,以确定适当的行动,在修复或删除。一项初步调查突出表明,需要改进评价方法。需要更详细的研究和完整的实验数据来验证新方法,并了解现有方法对此类缺陷的适用性。
英文摘要
Crack in Corrosion (CIC) has been identified in operating pipelines as a hybrid defect where a crack or crack colony occurs coincidentally with a significant amount of corrosion. It is of utmost importance to develop a reliable and consistent means of evaluating the remaining strength of CIC defects to determine the appropriate action in terms of repair or removal. A preliminary investigation has highlighted the need for improved evaluation methods. More detailed studies and complete experimental data are required to validate new methods and understand the applicability of existing methods to this type of defect.
