摘要:

以某电厂埋地供水管道为例,通过管道整体运行情况调研和局部重点腐蚀及泄漏部位定点开挖检测相结合,利用水质检测、土壤检测、腐蚀形貌观察、腐蚀缺陷测量、管壁厚度测量、腐蚀电位测量和超声导波测量等方法,综合评估了该供水管道的腐蚀现状,并对该埋地管道提出了针对性的修复方案。

Abstract:

Took a power plant’s buried water supply pipeline as example, by study on overall operation condition, corrosive and leakage area excavation, water quality monitoring, soil test, corrosion measurement, pipe thickness measurement, corrosion potential test and other methods, the corrosion condition of water supply pipe was evaluated. Repairing plan for the buried pipe was indicated.
