| Résumé : |
Over the past 40 decades, pipeline industries have evolved with new age of coating technologies which continuously provide better and better protection against corrosion. It has become standard industry practice to apply both internal and external coatings to the line pipes to overcome the problem associated with bare pipes i.e. rough internal surface of steel pipes and the build-up of deposits and formation of corrosion products with the service atmosphere. The concept of internal flow coating for transmission pipelines was first developed in the 1950s to counter the adverse effects on pipeline capacity, operation and pumping costs. This coating helps to increase the flow rate of transmission fluid because of reduction in friction and therefore increases the output. Similarly to protect the pipes externally, fusion bond-epoxy (FBE) coating systems were introduced in the 1960s which form a barrier between the metal surface of the pipe and the surrounding environment thus providing protection against corrosion. |
