| 摘 要： | 模拟高酸性气田集输系统条件，通过电化学腐蚀失重、氢致开裂和硫化物应力开裂试验对L360管道焊缝进行了耐蚀性研究。结果表明，添加缓蚀剂前后焊缝的腐蚀速率分别为0．437mm／a和0．102mm／a，腐蚀产物包括FeC03，FeS，FeO（OH）和FeO，焊缝没有出现氢致开裂和硫化物应力开裂，但发现少许氢鼓泡。

| Abstract: | Under the conditions of simulated gas-gathering line system of high sour gas well,the anti-corrosion of L360 pipe welds was studied through the electrochemical test,hydrogen induced corrosion(HIC) test and sulfide stress cracking(SSC) test.The results indicated the that corrosion rates before and after corrosion inhibitor addition were 0.437mm/a and 0.102mm/a respectively, and the corrosion products were FeCO_3,FeS,FeO(OH)and FeO.No HIC and SSC cracks were found in the pipe welds,but some hydrogen blisterin... |
