THE INFLUENCE OF SOME CORROSIVE ENVIRONMENTS ON THE WORKING EQUIPMENT OF THE HEAT EXCHANGERS

Abstract

The degradation of the structures made by steel or other metallic materials is more intense if on those structures a corrosive environment acts simultaneously with the variable mechanical stresses This process is called fatigue in corrosive environment or corrosion fatigue and has different causes and effects compared to the degradation due to the single action either of the mechanical stress, or only due to the corrosive environment. The process of degragation by a combined effect of the mechanical stresses together with a corrosive environment is intensified when the metallic structure is in contact with liquide corrosive agents., as it usually happens in cas of the equipment of the energetic industry.
