高压贫胺液泵最小流量线副线的腐蚀

Corrosion of Minimum Flow By-pass Line for High-pressure Lean Amine Pump

经过检测分析认为加氢裂化装置高压贫胺液泵最小流量控制阀副线的腐蚀开裂原因是胺液和硫 化氢的应力腐蚀和湍流腐蚀,管线振动加剧了腐蚀。

The test and analysis conclude that the cracking failure of minimum flow by-pass line of high-pressure lean amine pump in the hydrocracker are caused by sulfur stress corrosion and turbulent flow corrosion, which are aggravated by pipeline vibration.
