摘要
对煤气化装置耐硫变换工艺管道焊缝开裂的原因进行全面分析,根据失效分析的结论和建议,借鉴同类装置的经验对管道材料进行更换,消除了管道焊缝频繁开裂的安全隐患。
According to result from failure analysis and experience of similar plants,multi-analysis was made for cracking on the weld joints of pipes which served in the sulfur tolerant shift unit of Coal-Gasification Plant of Hubei Fertilizer Company of China Petroleum Chemical Corporation.The material of those pipes is changed and potential risk of safety is eliminated.
