摘要:: 伊朗三聚氰胺化工装置由我国某化工部门设计.该装置建于伊朗首都德黑兰北部地区,该处土壤电阻率较小,约在4～12 Ω·m之间,对地下钢铁设施具有强烈的腐蚀性.因此必须进行防腐处理,并投入电化学阴极保护.介绍该工程中地下设施的外防腐涂层工艺和牺牲阳极法阴极保护的选材、安装方式及技术要求。
The cyanuric triamide chemical equipment built in the northern area of Teheran of Iran was designed by a chemical unit of our country. In that area, the soil possesses strong corrosiveness to underground steel facilities owing to rather low electrical resistance of soil. The anti-corrosion treatment must be taken. In this paper, the material selection, installation and technical requirement of the external anti-corrosion coating and the cathodic protection with sacrificial anode used in the underground steel facility are descried.
