石墨衬里防腐设备的设计与施工

Design and Construction of Graphite Lining Corrosion Resistant Equipment

从防腐材料的选择、结构设计、衬里施工注意事项等方面 ,对含有氟化氢、稀氢氟酸等强腐蚀性介质的金属设备的防腐作了介绍。从实际使用的效果来看 ,对此类介质采用双层石墨板衬里、钢壳与石墨板之间设置天然硬质橡胶隔离层这一防腐方法是成功的。

This paper introduces the corrosion resistance of metal equipment containing strong corrosive medium such as hydrogen fluoride, hydrofluoric acid etc. from the view of corrosion resistant materials selection, structure design, precautions for lining construction etc. Based on the practical effect, the corrosion resistant method using double layer graphite lining and natural hard rubber layer in between steel shell and graphite plate is a successful method.
