腐蚀危险性的可靠评价和综合诊断对于管道的合理设计及安全运行具有重要意义。埋地管道高腐蚀危险区有微生物腐蚀及应力腐蚀断裂两种腐蚀形式。本文主要论述了对这两种腐蚀形式进行定性分析和定量评价的技术指标及腐蚀危险性的综合诊断方法。
The reliable evaluation and comprehensive diagnosis of corrosion risk are of great significance to the rational design and safe operation of the pipeline. Buried pipeline high corrosion risk zone microbial corrosion and stress corrosion cracking two forms of corrosion. This paper mainly discusses the qualitative analysis and quantitative evaluation of the two forms of corrosion technical indicators and the comprehensive diagnosis of corrosion risk.
