近年来,我国从国外引进了一批石油化工装置。有些设备、材料在装运前,虽采取了一定的防锈保养措施,但在开箱检验后到安装使用尚有一段存放期。如果在存放期间没有采取有效的防护措施,设备、材料仍会遭受腐蚀,影响使用。设备、材料存放中常用的防护措施有:用包装、密封的方法与外界隔离;使用干燥剂;充氮保护,防锈油脂和其它涂料的应用;气相缓蚀剂的应用等。
In recent years, China imported a number of petrochemical plants from abroad. Some equipment, materials, prior to shipment, although some rust preventive maintenance measures, but after opening the test to install and use there is still a period of storage. If there is no effective protective measures taken during storage, the equipment and materials will still be corroded and affected. Equipment, storage of materials commonly used protective measures are: packaging, sealed with the outside world; the use of desiccant; nitrogen protection, anti-rust grease and other coatings applications; gas phase corrosion inhibitor applications.
