However, it is recommended that the layer (2) which becomes the outer layer should be thicker than in the structure of the main invention. According to a second variant, the coating does not comprise the layer of primer (1), the layer of binder necessarily contains the polymer L2 and the surface is necessarily the outer surface of tubes. According to a third variant, the coating does not comprise the layer (2) and the layer (1) comprises a mixture of epoxy primer and polymer L2. The invention relates more particularly to the coating of the outer surface of tubes. These tubes are useful for the development of offshore hot oil wells, since it is necessary for the tubes which transport the hot oil to withstand corrosion by seawater.
