换热器无论是在工业和民用的换热应用是十分广泛的,其重要性也是显而宜见的,换热设备利用率的高低直接影响到工业生产效率以及成本的费用问题。据有效数据显示,换热器在化工建设中约占投资的20%,因此,换热器的利用率及寿命是值得研究的重要问题。由换热器的损坏原因来看,腐蚀是一个十分重要的原因,而且换热器的腐蚀是大量的普遍存在的,能够
The heat exchangers are widely used in both industrial and civil heat exchange applications. The importance of the heat exchangers is also obvious. The utilization rate of the heat exchangers directly affects the industrial production efficiency and the cost of the heat exchangers. According to the available data, heat exchangers account for about 20% of the investment in chemical construction. Therefore, the utilization rate and life expectancy of heat exchangers are important issues to be studied. Corrosion is a very important reason for the damage of the heat exchanger, and the corrosion of the heat exchanger is ubiquitous and capable of
