摘要
文中针对HDPE装置的不锈钢管线发生腐蚀的原因进行分析,对腐蚀部位液体进行分析,确定Cl-腐蚀,同时由于HDPE装置工艺特点,腐蚀还造成干燥机加热蒸汽管泄漏、水冷器泄漏等问题,为此提出防止Cl-腐蚀的防范措施,包括设计上选用更加耐腐蚀的金属材料、生产重加强泄漏管理、使用无机防腐涂料等,经实际应用效果好,保证HDPE装置稳定生产。
This paper analyzed the causes of corrosion in stainless steel pipeline of HDPE plant,checked the liquid at the corrosion site and finally determined it was Cl-corrosion which also caused the problems such as leakage of heating steam pipe of dryer and leakage of water cooler due to the technological characteristics.Therefore,preventive measures to prevent Cl-corrosion were proposed,such as,the use of more corrosion-resistant metal materials in the design,enhancement of leakage management,the use of inorganic anti-corrosion coatings,etc.,which got the good effect on application,to ensure the stable production of HDPE plant.
