Discussed on the Atmospheric Corrosion and Protection of Pressure Devices

The sulfur content of crude oil processing common and serious corrosion of the low-temperature corrosion of naphtha site,wet hydrogen sulfide corrosion,high temperature sulfur corrosion of a variety of corrosion types,the formation of corrosive medium,corrosion,corrosion mechanism,as well as to take the process anti-corrosion measures and materials were discussed.At the same time,sulfuric acid dew point corrosion,and even many sulfuric acid stress corrosion cracking of two particular types of corrosion,but also from the corrosion mechanism and anti-corrosion measures were introduced.
