摘要
某工程运行4年多,检查发现热水管道腐蚀、结垢情况严重。经定性分析,认为管材和热交换器自身材质、两种材质的管道连接处理、管道焊接处引起缝隙腐蚀、水中溶解氧等几方面是造成管道腐蚀、结垢的主要原因。针对上述原因,采取更换管材、更换热交换器、增设全程水处理器的处理方法,解决管道腐蚀和结垢问题,改造后运行一年多时间,情况良好。
A project had rosed and scaled seriously. runned for more than 4 years, inspection found that hot water pipelines were cor Through qualitative analysis ,the major causes of pipeline corrosion and scaling the materials of pipeline and heat exchanger, two kinds of connection processing, the crevice corrosion of pipeline welding, dissolved oxygen and other aspects. For the above reasons, processing method of solving the problem of pipeline corrosion and scaling is replacing pipeline and heat exchanger and adding the water pro cessor. It is running fine more than one year with these renovation.
