1)  organic sulfide corrosion
有机硫化物腐蚀
2)  sulfide stress corrosion
硫化物应力腐蚀
1.

针对天然气输送过程中管道设备可能出现的失效形式,并结合“西气东输”工程实际,从介质环境、材料使用、应力特征等几方面入手,分析了天然气输送过程中的硫化物应力腐蚀问题,并提出相应的预防措施。
3)  sulphide corrosion
硫化腐蚀
1.
The results showed that the tubes had suffered the high temperature oxidative and sulphide corrosion for the operation temperature being higher than the suitable, though reheating tubes were made by Cr5Mo steel which has good anticorrosion and mechanism performance.
应用扫描电子显微镜、能谱分析以及X射线衍射仪对焦化加热炉炉管的高温腐蚀形貌,腐蚀物成分以及物相进行了分析,结果表明,尽管加热炉管用材是抗腐蚀性能和高温机械性能均良好的Cr5Mo钢,但由于炉膛操作温度过高,且燃料中含硫,炉管不但发生高温氧化腐蚀,还发生硫化腐蚀,使破坏加速,最终导致炉管失效。
4)  sulfur corrosion

5)  sulfue corrosion product
硫腐蚀产物
6)  SSCC
硫化物应力腐蚀开裂
1.
Constant load tensile test was adopted to study the influence of welding material match and alloy element content on SSCC(sulfide stress corrosion cracking) of domestic pipeline steels.

补充资料:有机硫化物腐蚀
分子式:
CAS号:

性质:高温腐蚀的一种类型。主要发生在原油蒸馏和裂解装置中。原油或其他物质中含有的有机硫化物,如硫醇、硫醚、噻吩、多硫化物等,在高温下分解形成硫化氢,腐蚀碳钢和低合金钢制设备管道、管件等。温度在400~450℃之间时腐蚀最为严重,提高钢中的含铬量可显著改善其抗有机硫化物腐蚀的能力。
