NOVELTY - The utility model claims a new one based on a kind of novel oil and graphite, including inside pipe and outside pipe, the inner is hollow structure used for transporting oil, outside of inner tube is outer pipe, the outside pipe surface coating with one layer graphene, the graphene layer thickness is 10 to 100 (mu) m, inside pipe and outside pipe provided with insulating layer between, the utility model of new oil from inside to outside in turn by butyl rubber layer, an inner insulating layer, outer pipe, multiple layer graphene structure composed of, at the same time with corrosion resistance, reducing noise, effect of heat preservation, reducing external environment for pipeline in influence of petroleum, the graphene layer has good heat stability and the chemistry stability, strong corrosion resistance, can prevent the safety leakage is suitable for wide range.
