▎ 摘　　要

NOVELTY - Preparing pipeline joint with a loaded graphene film, comprises preparing a graphene film-metal foil composite material using CVD (Chemical Vapor Deposition) method; and using graphene film transfer method to transfer and adhere the graphene film from the graphene film-metal foil composite material onto the surface of the metal pipeline joint. USE - Preparation method of pipeline joint of load graphene used in flaring process of flared type interface of aircraft hydraulic and fuel system. Can also be used in processing and manufacturing process. ADVANTAGE - The method is capable of repairing the occurrence of the pipeline joint of the atom-level gap, and improves the sealing property of the load graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a pipeline joint of load graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the graphene film adhered to the flared pipeline joint (Drawing includes non-English language text).
