The inner layer is the layer in contact with the fluid being transferred. According to one embodiment of the invention, the inner layer (4) contains an electrically conducting material, producing a surface resistivity of less than 106Ω. According to another embodiment of the invention, the inner layer (4) contains essentially no electrically conducting material and the tube includes a layer (4a) that adheres to the layer (4), this layer is made of polyamide and contains an electrically conducting material producing a surface resistivity of less than 106Ω This layer (4a) becomes the inner layer. These tubes may have an outside diameter of 6 to 110 mm and a thickness of around 0.5 to 5 mm.

    摘要： The present invention relates to a multilayer tube comprising, in its radial direction from the outside inwards: an outer layer formed from a polyamide, a layer formed from a copolyamide, a layer formed from an EVOH, a layer formed from a copolyamide, an inner layer formed from a polyamide, the layers being successive and adhering to one another in their respective contact region. Advantageously, the inner layer is formed by a compound based on a polyamide and electrically conducting carbon black, producing a surface resistivity of less than 106 Ω/?. The outside diameter of these tubes may range from 6 to 110 mm and the wall thickness may be from 0.5 to 5 mm. Advantageously, the petrol tube according to the invention has an outside diameter ranging from 6 to 12 mm and a total wall thickness of 0.36 mm to 1.95 mm, namely: a thickness of 50 to 700 μm for the polyamide outer layer, a thickness of 10 to 150 μm for the copolyamide layers, a thickness of 10 to 200 μm for the EVOH layer, a thickness of 100 to 500 μm for the polyamide inner layer possibly filled with electrically conducting carbon black. The tube of the present invention has a very low permeability to petrol, particularly to hydrocarbons and their additives, and in particular to alcohols, such as methanol and ethanol, or to ethers, such as MTBE or ETBE. These tubes also have good resistance to engine lubrication oils and fuels.
