Oil conveying pipe with composite section

A composite section oil pipeline comprises a pipeline body, and the pipeline body comprises a stainless steel layer, a low-carbon steel layer, an ultra-high performance concrete (UHPC) layer and a fiber reinforced composite (FRP) layer from outside to inside. The stainless steel layer and the low-carbon steel layer are combined into a whole through extrusion, so that the strength, plasticity and toughness are enhanced; the ultra-high performance concrete (UHPC) layer is arranged between the low-carbon steel layer and the fiber reinforced composite (FRP) layer, so that the wear resistance and explosion resistance of the pipeline are remarkably improved; the fiber reinforced composite (FRP) layer arranged on the inner side of the pipeline is light and hard, smooth in surface, non-conducting, high in mechanical strength and resistant to corrosion, the problem that petroleum corrodes the pipeline is solved, and running resistance is small. The utility model has the advantages of simple structure, high strength, c
