A new nano-composite coating is developed by using the blending method for use inside the pipe of natural gas. The "systematic effect" and the "cascading effect" produced by the hybrid composition of nanoparticles and the matrix are used to achieve optimization for the complex coating on functions such as anti-corrosion and drag reduction. The difficult-to-coordinate bottleneck problem which is an "internal and external trouble" existing inside the pipe will be solved at the same time. The optimized composite coating, on one hand, can exert a "super bonding force" with the wall of the pipe which is not easy to peel; on the other hand, the coating can show a "super alienation" behavior to the medium which is not easy to scale. An acceleration simulation method has been used to evaluate the performance indicators of anti-corrosion and drag reduction through experiments. The results of experiments show that the composite coating added with nano-additives shows a decline of surface roughness and visible latent function of drag reduction. The results of the experiments also show that the corrosion rate has declined by an average of more than one time.
