摘要:

通过研究石油化工行业中化工浓硫酸管道的防腐设计以及浓硫酸对碳钢管道材质腐蚀性能,在检测并收集相关数据对比后,对浓硫酸管道的腐蚀重点部位进行分析,并对比2条浓硫酸管道的腐蚀情况,分析不同条件,不同部位下浓硫酸对碳钢管道的腐蚀速率差异的原因,找到防腐重点的规律,以减少浓硫酸管道因腐蚀造成的泄漏等危害。

Abstract:

This paper mainly studies the anti-corrosion design of chemical concentrated sulfuric acid pipelines in the petrochemical industry and the corrosion performance of concentrated sulfuric acid on carbon steel pipeline materials, analyzes the key corrosion parts of the concentrated sulfuric acid pipelines based on the test and the collection of relevant data, and compares the corrosion of two concentrated sulfuric acid pipelines. The reasons for the difference in corrosion rates of carbon steel pipelines in different parts under different conditions are analyzed, and the key rules for anti-corrosion are found out to reduce the leakage caused by the corrosion of concentrated sulfuric acid pipelines.

Key words: concentrated sulfuric acid, piping, corrosion, detection
