what is wet corrosion in oil and gas industry?

wet corrosion There are many ways to classify corrosion. However, in general, corrosion is divided into 3 major groups namely Wet corrosion, Dry corrosion, and biological corrosion. Wet corrosion, as the name implies, occurs only in the presence of an aqueous solution or an electrolyte. Dry corrosion or dry corrosion occurs when there is no fluid present or temperature above the dew point of the environment. Biological corrosion or biological corrosion is a specific type of wet corrosion that occurs in the presence of living organisms. sometimes wet corrosion is named as aqueous corrosion. Wet corrosion is an electrochemical process,[…]

what is Stress corrosion cracking ?

Stress Corrosion cracking (SCC) this phenomenon can be defined as material cracking due to the combined effect of static stress and corrosion. The stress involved can be residual stress and actual stress from an external load. The corrosion that occurs is generally very localized. Localized corrosion on the surface of the material usually acts as a stress raiser or stress concentrator. This corrosive cracking can be either transgranular or intergranular cracking depending on the type of alloy, metallurgical and environmental conditions. there are 3 main causes that determine the occurrence of Stress Corrosion Cracking are: Tensile stress. This tensile stress[…]
