Embodiment Construction

[0031] In the first embodiment according to FIG. 1 , the initially uncoated outer surface of the double-walled steel pipe 1 has been coated with an aluminum layer 2 . In this case, the aluminum layer 2 is expediently coated according to a hot-dipping process. Directly on the aluminum layer 2 is arranged an aluminum oxide layer 3 which forms the outer surface of the vehicle conduit.

[0032] in accordance with figure 2 In the second embodiment, a nickel layer 4 is firstly plated on the outer surface of the double-walled steel pipe 1 . The aluminum layer 2 is arranged on the nickel layer 4 , wherein the aluminum layer 2 is expediently likewise applied using a hot-dipping process. The aluminum oxide layer 3 is in contact with the aluminum layer 2 on the outside, and the aluminum oxide layer 3 is in accordance with figure 2 In the embodiment of the same, the outer surface of the automobile pipeline is formed. in manufacturing based on figure 2 For the double-walled steel pipe...

Abstract

Motor vehicle pipeline comprising a metal tube with an aluminum layer is applied to the outer surface of the metal tube. An aluminum oxide layer is provided on the outer surface of the aluminum layer. The aluminum oxide layer forms the outer layer of the motor vehicle pipeline.

Description

technical field [0001] The invention relates to a vehicle pipeline having a metal tube, wherein the outer surface of the metal tube is coated with an aluminum layer. The invention also relates to a method for producing such a vehicle line. Hereinafter, the automotive pipeline is also referred to simply as the pipeline. Background technique [0002] Automotive lines of the above-mentioned type are basically known in practice. Such known automotive conduits usually have at least one plastic layer arranged on an aluminum layer, which usually forms the outer layer of the automotive conduit and also serves for corrosion protection and abrasive wear protection of the conduit. It is known from practice that many automotive lines have to be produced relatively expensively. Contents of the invention [0003] The technical problem underlying the present invention is to provide a motor vehicle line of the type mentioned at the outset, which can be produced relatively simply and in...
