At least one of which continuous fiber prepreg tape intermediate layer it is provided with between external tube layer；Described continuous fiber prepreg tape intermediate layer by hoop and
The longitudinally staggered multilamellar continuous fiber prepreg tape being wrapped in polyethylene double-resisting in tube layer is formed by laser action welding.
Preferably, the epoxy drag reduction undercoating that described plastic composite pipe inner surface is arranged it is additionally included in.
Preferably, the described internally coated thickness of epoxy drag reduction is 0.1-0.2mm.
Preferably, described epoxy powder anti-corrosion layer is mixed by epoxy powder and adhesive, and respectively with described plastics
Multiple tube and described flexible polyurea outer jacket bonding are arranged.
Preferably, in described polyethylene double-resisting, the thickness of tube layer and described polyethylene double-resisting external tube layer is 1-2mm.
The beneficial effects of the utility model are: the internal layer of the plastic composite pipe of described nonmetal compound flexible petroleum pipeline
Use epoxy drag reduction undercoating, and the epoxy powder anti-corrosion layer that sets gradually of described plastic composite pipe outer surface and flexible polyurea
Outer jacket, the most described nonmetal compound flexible petroleum pipeline has excellent resistance to impact, water proofing property and has relatively low defeated
Oil resistance.
