Corrosion and Protection of Heat Exchanger in Petrochemical Units

In petrochemical production process,heat exchangers always lead to corrosion leakage,even to unit shutdown,which affects long period running of the units and causes severe financial loss.It is necessary to strengthen anti-corrosion job of heat exchangers to ensure long period production of the units.Corrosion status of heat exchangers in petrochemical units was introduced,and anti-corrosion technologies and application instances were summed up.Suggestion and expectation were pointed out.
