<p>A pipe (11) for conveying liquid and/or gas comprises a liquid-tight and/or gastight inner plastic layer (2), and an outer plastic layer (3) which surrounds the inner layer. The outer plastic layer is foamed in such a way that it can be deformed plastically under the influence of a local load. The foamed outer plastic layer allows plastic deformation to take place under a local load which is lower than the local load which leads to plastic deformation in the inner plastic layer.</p> |
