合成氨厂热交换器腐蚀与对策一般中型合成氨厂热交换器很容易被腐蚀,普通碳钢制造的设备一般使用寿命不足一年,有时甚至三个月左右便发生列管腐蚀、穿孔泄漏的现象。腐蚀部位一般均在半水煤气进口端约1m长的列管上。产生腐蚀破坏的原因主要有:1.当半水煤气经饱和热水塔增湿后再
Ammonia Plant Heat Exchanger Corrosion and Countermeasures General medium-sized ammonia plant heat exchangers can easily be corroded. Ordinary carbon steel equipment generally has a service life of less than one year, sometimes even three months or so will occur tube corrosion, perforation leakage phenomenon. Corrosion sites are generally about semi-water gas inlet about 1m long tube. The main causes of corrosion damage are: 1. When the semi-water gas through the saturated hot water tower after humidification
