1, installation process
Pressure vessel corrosion and its manufacturing and installation process also has a great relationship, especially the residual stress caused by cold working is an important cause of stress corrosion rupture, in the case of cold working moulding must be used to pay attention to the elimination of stress heat treatment or shot blasting in order to eliminate the cold working residual stress. If the stress corrosion situation is particularly serious, the overall stress relief heat treatment or effective local heat treatment operation is essential.
2、Alloying
The base metal is added to the relevant alloy composition, the use of alloy corrosion resistance to enhance the overall corrosion resistance of the pressure vessel.
