摘要随着国内液化天然气(LNG)项目逐步进入运营期,接收站内LNG设备面临的腐蚀问题日益突出。本文针对LNG卸料臂的防腐蚀涂层选择工作,通过比较6种常用防腐蚀涂料的性能,并结合现场涂装试验,选择了一种既可以满足超低温(-162℃)至常温(60℃)冷热循环工况,又具有优异防腐蚀和耐紫外线性能的新型超低温防腐蚀涂层体系,并成功应用于LNG卸料臂表面涂装。新型超低温防腐蚀涂层体系的综合性能优于原日本设备厂家提供的涂层体系,具有较好的潜在应用价值。With the liquid nature gas （LNG） projects gradually going into the operating period, the LNG equipment in the receiving station is challenged increasingly by the corrosion problem. By comparing the performance of six kinds of anticorrosive coatings and combining with the field coating application test results, a new type of ultralow temperature corrosion re- sistant coating system which can tolerate temperature cycling from -162 ℃ to 60 ℃ was se- lected and successfully applied on the surface of LNG unloading arm＇s stainless pipe. The per- formance of the new ultralow temperature corrosion resistant coating system is better than the o- riginal coating system, and it is expected to have a good potential application value. 机构地区广东大鹏液化天然气有限公司 出处《涂料工业》 CAS CSCD 北大核心 2016年第4期58-60,65,共4页Paint & Coatings Industry 关键词超低温 防腐蚀涂料 LNG 卸料臂uhralow temperature anticorrosive coatings LNG unloading arm 分类号 TQ635.2 [化学工程—精细化工]
