Component replacement for creating a thermally isolated. Pipeline.

The object of the innovation is a set of components for the creation of a heat-insulated pipeline, consisting of two or more metal pipes, in particular steel pipes, which are welded together at the assembly point, each of which has a synthetic foam insulating layer and a r

outer plastic protective tube are sheathed in such a way that all pipe ends to be welded are exposed.

During the actual pipeline by welding de: individual steel pipes or the like. at their connection points, can be properly sealed in a simple V / eise,
