炼油厂工艺管线腐蚀失效及选材

Corrosion Cracking of Regenerator and Safe Operation

炼油厂工艺管线中的介质多为易燃烃类 ,一旦管线腐蚀失效即可酿成火灾。文章介绍了 4个失效实例 (有的是因为错用材质 ,有的是误用焊料 )

Since the fluid in most of the refinery process pipelines is flammable hydrocarbons, the corrosion failure of the pipeline can easily cause fire emergency. 4 corrosion failure cases ( some were the results of inappropriate selection of materials and some were the outcome of misusing welding materials) were introduced and the principles of material selection for refinery operation were discussed.
