| 摘要: |
| 在开发含H2S油气田中常接触含H2S介质。由于H2S存在,当采用碳钢时除考虑化学失重腐蚀外,压力容器和压力管道受压元件还存在硫化物应力腐蚀开裂(SSC)和氢致开裂(HIC),如处理不当,将会使压力容器和管道突然破裂,危及安全。本文从试验和工程实践中提出了硫化物应力腐蚀开裂(SSC)和氢致开裂(HIC)评定、鉴定、评审和具体作法。 |

| Abstract: |
| H2S is usually encountered in development of oil and gas fields.If carbon steel is used for pressure parts of pressure vessels and pipelines,existence of H2S will not only result in chemical weightlessness corrosion on such parts,but also result in sulfide stress cracking(SSC) and hydrogen-induced cracking(HIC),which will lead to sudden breaking of pressure vessels and pipelines and endanger safety.The specific methods of the assessment,identification and review on SSC and HIC and their detailed practices are put forward in this paper according to test data and engineering practices. |
