复合管在硫酸铵生产中的应用研究

Application and research on composite pipe in ammonium sulfate production

介绍了硫酸铵母液对316L不锈钢管道的腐蚀情况和腐蚀原因,分析了内衬玻璃钢管、钢骨架聚乙烯塑料复合管、钢衬聚乙烯管道的特点以及在硫酸铵生产中的使用情况。经对比,钢骨架聚乙烯塑料复合管是理想材料。

This paper introduces the corrosion and reasons for the corrosion of 316L stainless condition caused by ammonium sulfate mother liquor steel pipe, analyzes the features of glass lined pipe, steel framed polyethylene plastic pipe and polyethylene lined steel pipe, and service condition in the production of ammonium sulfate. Steel framed polyethylene plastic pipe is the ideal material according to the comparison.
