Abstract: The developing actualities and technological level of coating material used in internal coating for gas transmission pipelines at home and abroad are described. In the paper, the features and performance indexes of bi-component liquid epoxy coating material and FEE to be widely used in long distance gas transmission pipelines at home and abroad are emphatically introduced. The authors consider that the foreign experiences in studying, producing and applying coating materials in gas transmission pipelines can be used for reference for several gas transmission pipelines to be put into construction in China, especially in drag reduction of gas pipeline with the coating materials.
