Oil and natural gas are both corrosive, placing extremely high demands on the corrosion resistance of pipelines. The corrosion resistance of a pipeline directly affects its lifespan. So, how can we improve the corrosion resistance of pipelines?
External Anti-corrosion Coating
External anti-corrosion coating is applied to the outer surface of the pipeline, especially for underwater and underground pipelines, which are subject to corrosion not only from the medium but also from seawater and soil. Commonly used oil and gas pipes include 3LPE, 3LPP, FBE, and 2LPE.
Internal Anti-corrosion Coating
Internal anti-corrosion coating prevents corrosion from the transported medium. Using an internal anti-corrosion coating on oil and gas pipes not only provides corrosion protection but also smooths the inner wall, increasing flow velocity and thus improving transport efficiency. We can customize your internal coating according to the medium you are transporting.
Catholic Protection
Catholic protection is a chemical corrosion protection method. An electric current is applied to the outside of the pipeline, making the pipeline the cathode of a chemical circuit. The cathode itself inhibits the loss of electrons from the pipeline, forming a chemical corrosion protection technology.
