NOVELTY - The utility model claims a new buried oil and gas pipeline joint, comprising two butted pipeline, the outer wall of the two abutting pipe ends are respectively equipped with graphene anti-corrosion primer layer, covered by the graphene anti-corrosion primer layer with anti-corrosion adhesive tape 3G, the outer surface of said 3G anti-corrosion adhesive tape is set with graphene light-curing protective layer. The utility model adopts anticorrosive primer is combined with the light curing layer to manufacture a repairing, which greatly improves the service life of the pipeline, can protect the pipeline for 30 years, is increased by 5 times. it avoids the environment pollution caused by the pipeline leakage.
