对某厂服役了10年的4台石油液化气球罐定检中发现了严重的氢鼓泡现象,导致无法修复的材料劣化。氢腐蚀现象产生速度快、不可修复、危害极大。在编制长期在H2S介质环境中使用的容器的检验工艺中加强氢腐蚀缺陷的检测十分重要。
A serious bubbling of hydrogen was found in the inspection of four LPG domes, which served a plant for 10 years, resulting in irreparable material deterioration. Hydrogen corrosion phenomenon produces fast, can not be repaired, endangering great. It is important to enhance the detection of hydrogen corrosion defects in the inspection process for the preparation of long-term containers for use in H2S media environments.
