Comparison of pipeline coating systems

Pipelines are the energy highways of the world. They are the most important medium for the transportation of oil, gas, petrochemicals and water. It is important that pipelines perform safely throughout their entire Engineered Design Life. This is achieved most effectively by the combination of cathodic protection and protective coatings in order to avoid high maintenance costs and potential environmental damage arising from leakage due to corrosion breakdown. Good ageing resistance, high mechanical properties to avoid any damages during transportation and pipe laying, as well as resistance to corrosive soils, chemicals and micro-organisms are essential performance requirements that Epoxy powders must meet.
