摘要
随着石油化工的发展,国内石油深度开采和中东石油输入的持续增加,原料中的硫元素含量逐渐增加,硫化氢对焊接接头的腐蚀会导致整个构件的失效,给生产安全带来极大威胁。国内外研究人员就硫化氢对高强度低合金(HSLA)钢焊接接头的应力腐蚀给予了很大关注。简要阐述了在湿硫化氢环境下,HSLA钢焊接接头在使用时发生应力腐蚀开裂的机理,讨论了影响焊接接头的应力腐蚀的因素,总结了探索应力腐蚀时的不同实验方法,并与碳钢的应力腐蚀进行了对比。
With the development of petrochemical industry, the deep exploitation of domestic petroleum and the continuous increase of oil input from the Middle East, the sulfur content in raw materials is gradually increased. The corrosion of hydrogen sulfide on welded joints can lead to the failure of the whole component, bringing great threat to production safety. Researchers at home and abroad have paid great attention to the stress corrosion of high-strength low-alloy(HSLA) steel welded joints caused by hydrogen sulfide. In this paper, the mechanism of stress corrosion cracking of HSLA steel welded joints in service in a wet hydrogen sulfide environment was briefly described, and the factors that influencing stress corrosion of welded joints were discussed. Furthermore, different experimental methods for exploring stress corrosion were summarized and the stress corrosion was compared with that of carbon steel.
