摘要
针对油气田站内换热设备频繁发生的腐蚀失效问题,进行了案例调研分析。结果发现,腐蚀穿孔为换热设备主要的失效类型,其多发生在管束本体以及管束与管板连接的焊缝位置,服役介质多为含水油气与循环水。换热器的失效不仅与换热器的材料、服役介质有关,也与换热器的结构设计、焊接工艺及现场安装位置与生产管理制度有关。对此,分别从选材设计、结构优化、涂层保护及安装施工与管理优化等四个方面提出了针对性的防控措施,以保障油气生产系统的安全、稳定运行。
In view of frequent corrosion failure of heat exchange equipment in oil and gas field stations,a case study and analysis was carried out.It was found that corrosion perforation was the main failure type of the heat exchangers,which mostly occurred in tube bundle bodies and the weld positions between tube bundle and tube sheet.The service medium was mostly water-containing oil and gas and circulating water.The failure of heat exchangers were not only related to the material and service medium of heat exchangers,but also related to the structural design,welding process,on-site installation location and production management system of heat exchangers.Specific prevention and control measures were proposed from the four aspects of material selection design,structural optimization,coating protection,installation and construction,and management optimization to ensure the safe and stable operation of the oil and gas production system.
