石油液化气钢瓶腐蚀穿孔失效分析
Failure analysis of pitting corrosion on liquefied petroleum gas cylinders
【摘要】 某些经定期检验后的石油液化气钢瓶在使用中发生了穿孔泄漏,其原因是液化气中的含硫杂质附着于钢瓶中,在水和氧的作用下,使钢瓶发生了阻塞电池腐蚀。
【Abstract】 The pitting happens during their normal use on some liquefied petroleum gas cylinders after the periodical check. This is caused by sulfur compound accumulated in the cylinder on which is acted by oxygen and water and occluded cell corrosion happens.
