Abstract

A double-wall pipe for a transportation means which includes an outer pipe and an inner pipe extending therein. The outer pipe has two pipe segments which are formed like half-shells and are joined together to form the outer pipe along the longitudinal edges thereof. In this way, it is possible to make both the outer pipe and the inner pipe of metal, such that the wall thickness of the inner pipe can be relatively small.
