设备保温层下的腐蚀与防治

Corrosion and Prevention of Equipment Under Thermal Insulation

由于原油成分复杂,性质不稳定,因而对设备的腐蚀也比较严重,原油设备的腐蚀问题引起广泛的关注。尤其是在节能降耗、保护环境的大前提下,各类炼油化工企业开始采用大量的保温材料,一种由保温材料带来的保温层下腐蚀,正在引起越来越多的关注和研究,主要就保温层下的腐蚀机理、预防机制、保温材料的正确选择等方面进行探讨。

Due to the complex composition and unstable properties of crude oil,the corrosion of equipment is also serious.The corrosion of crude oil equipment has attracted widespread attention.In particular,under the premise of energy conservation,consumption reduction and environmental protection,various types of oil refining and chemical companies have begun to use a large number of thermal insulation materials,and a type of insulation corrosion caused by thermal insulation materials is causing more and more attention and research.This article discusses the corrosion mechanism,prevention mechanism,and the correct selection of insulation materials under the insulation layer.
