摘要
为提高碳钢冷换设备的耐蚀性能,保证设备长周期安全运行,需施加各种表面防腐蚀保护技术,其中主要有涂料涂层保护、金属渗层保护和化学镀镍磷合金镀层保护3种。北京东方亿鹏传热技术有限责任公司的创新工艺是在同一台换热器上,可以施加两种表面保护技术,以满足不同介质的防腐蚀要求。
In order to increase the property of corrosion resistance for carbon steel cooler and heat transfer exchanger, and ensure the long period operation of equipment, various surface corrosion protective technology should be provided. Among them three main kinds was paint coating protection, metallic infiltration layer protection and chemical nickel phosphor plating alloy layer protection. The new process of Beijing Dongfang Yipeng heat transfer company Ltd. was that two kinds of surface protective technology could be made on one and the same heat exchanger to satisfy the requirement of corrosion protection for different medium.
