Fusion-Bonded Epoxys Effects On Cathodic Disbondment
Selecting suitable coating for buried pipelines is one of the most important parts of protecting external surfaces and reducing the corrosion rate. Controlling corrosion through cathodic protection and specific coating reduces the cathodic current; however, this creates an alkaline environment in the interface of the coating that covers the cathode surface, which can lead to disbondment. Disbondment of polyethylene-coated buried pipelines is one of the major problems faced by operators. In such cases, there is a risk of stress corrosion cracking (SCC). Suitable coatings and cathodic protection control corrosion of pipelines can increase the effectiveness of protection when used
