摘要
中国石油天然气股份有限公司锦西石化分公司蒸馏装置炼制辽河低硫高环烷酸原油对设备、管线及阀门有较强的腐蚀作用。在230～400℃下,沈阳阀门研究所研制的以SF-5T作密封面材料的阀门具有良好的抗冲蚀性、抗氧化性以及热态组织稳定性。试验及现场运行结果证明,SF-5T堆焊合金材料使用性能可靠,是加工酸值较高的辽河原油装置抗环烷酸腐蚀阀门的理想密封材料。
Liaohe low sulfur and high naphthenic acid crude is processed in the distillation unitin Jinxi Petrochemical Company, which seriously corroded the eqiuipment, pipes and valves. The valveswith SF-5T alloy as sealing material developed by Shenyang Valve Research Institute possesses the per-formance of anti-impingement attack, anti-oxidation property and good thermal stability at a temperaturerange of 230℃ to 400℃. The laboratory test and the site running showed that the SF-5T overlay wel-ding alloy material has reliable service performance, which is. an ideal valve sealing material for resistingnaphthenic acid corrosion in processing high-acidity Liaohe crude.
