General corrosion:

General corrosion including water and steel commonly results from chemical action where the steel surface oxidizes, building iron oxide (rust).  Several of the systems and elements within the plant are made from iron.

A few standard methods related along with material selection which protect against common corrosion involve:

1. The use of corrosion-resistant materials like as stainless nickel and steel, chromium, and molybdenum alloys. (Remember that the corrosion is electrochemical through nature and the corrosion resistance of the stainless steels results from surface oxide films which interfere along with the electrochemical procedure.)

2.  The use of protective coatings like as epoxies and paints.

3. The application of nonmetallic and metallic coatings or linings to the surface that protects against corrosion, other than permits the material to retain its structural strength (for instance, a carbon steel pressure vessel along with stainless steel cladding as a liner).
