石化企业工艺法兰设备防腐蚀材料讨论
|
摘要
为了提高石化企业工艺法兰设备的防腐效果,结合大多数石化企业场所处工业腐蚀大气环境,分析了法兰腐蚀机理,并重点讨论了石化企业法兰设备包覆防腐工艺。通过选用蜡磁防腐材料与粘弹体防腐材料两种防腐性能优异的包覆防腐材料在部分石化企业实际应用,并逐步改进其包覆防腐工艺,经过几年的实际应用,两种防腐材料用于法兰防腐时均有较好实际应用效果,所以:蜡磁防腐材料与粘弹体防腐材料通过对其包覆防腐工艺改进均可在工艺法兰上应用,且针对部分滨临海边,长期受海洋高湿、高盐大气侵蚀的石化企业,防腐效果依然非常优异。
In order to improve the anti-corrosion effect of the process flange in petrochemical enterprises, combined with the high humidity and high salt sea environment in most petrochemical enterprises, and analysis of the flange equipment corrosion mechanism, and mainly discussed flange anti-corrosion maintenance methods in petrochemical enterprises. By choosing a wax tape anticorrosion material and the viscoelastic anticorrosive material with good anticorrosion performance in the practical application in some petrochemical enterprises, and gradually improve its coating anticorrosion technology, after several years of practical application, two kinds of anticorrosion materials used for flange when all have good application effect, so: through the coating anticorrosive process improvement of the wax tape anticorrosion material and viscoelastic anticorrosive material, both can be applied in petrochemical enterprises on the flange with aiming at part lies at the seaside, and the some petrochemical enterprises has long been eroded by the ocean's high humidity and high salt atmosphere, the anti-corrosion effect is of the wax tape anticorrosion material and viscoelastic anticorrosive material still very outstanding.
