Corrosion

Corrosion in piping systems caused by thermodynamic and electrochemical processes - corrosion problems and methods of protection and prevention.

Corrosion Type	Cause	Prevention Method	Protection Level
General Corrosion	Thermodynamic oxidation	Coatings and inhibitors	High
Pitting	Electrochemical attack	Stainless steel or alloys	Medium
Galvanic Corrosion	Dissimilar metals contact	Isolate metals or use sacrificial anodes	Medium
Stress Corrosion Cracking	Stress + corrosive environment	Stress relief and material selection	High
Erosion Corrosion	Fluid flow and chemical attack	Reduce flow velocity and use resistant materials	Low
