废硫酸再生装置的管道材料设计
|
摘要
介绍了废硫酸再生装置管道耐硫酸腐蚀性能的影响因素及管道材料的设计原则。影响管道耐硫酸腐蚀性能的因素包括温度、流速、浓度、杂质等。废酸再生装置常用的管道材料包括金属管道、非金属衬里管道、玻璃钢管道。详细描述了不同材料对不同浓度硫酸的耐蚀表现,供设计人员在项目设计过程中根据实际情况参考使用。
The influence factors of sulphuric acid corrosion resistance and the design principles of pipeline materials for the waste sulphuric acid regenerating plant are introduced. There are some factors that affect the sulphuric acid corrosion resistance,including temperature,flow rate,concentration,impurities and so on. Common pipeline material such as metallic pipe,lined steel pipe,FRP are used in the waste sulphuric acid regenerating plant. The corrosion resistance of different materials to different concentrations of sulphuric acid is described in detail,so that the designers can use as a reference base on the concrete conditions.
