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。
PetroChina Jinxi Petrochemical Company distillation unit refining Liaohe low sulfur high naphthenic acid crude oil equipment, pipelines and valves have a strong corrosive effect. In the 230 ~ 400 ℃, Shenyang Valve Research Institute developed SF-5T as the sealing surface of the valve material has good erosion resistance, oxidation resistance and thermal stability of the organization. Tests and field operation results show that SF-5T surfacing alloy material with reliable performance, processing Liaohe crude oil acid value higher naphthenic acid corrosion valve ideal sealing material.
