石油化工装置配管的腐蚀及防腐对策研究

摘要

配管是石油化工行业中必不可少的设备之一，在长时间运行的过程中常因受管道内部流体的性质、温度、压力、流速及滞留时间等因素的影响而发生腐蚀，甚至导致泄漏而引发事故。本文对石油化工装置配管的腐蚀原因进行了分析，并且研究了相应的防腐措施。%Piping in petrochemical industry was one of the essential equipment, which was often corroded because of the pipeline internal fluid properties, temperature, pressure, flow, residence time and other factors in the long time run- ning process, and even lead to accident caused by leakage. The reasons of petrochemical piping corrosion were analyzed and the corresponding measures of corrosion prevention were proposed.
