Abstract
The insulated pipe arrangement comprises at least two pipe bodies, each of which has a flexible inner fluid-guiding pipe, which is enclosed by an insulating layer made of elastomeric or thermoplastic foam, a protective film made of a thermoplastic, elastomer, or duromer of high-density being arranged around the insulating layer. The pipe bodies are bonded on opposing peripheral parts of their protective film by a layer of an adhesive which allows detachment of the adhesive bond without the protective film being damaged and which produces a renewed adhesive bond after detachment of the adhesive bond when the peripheral parts of the previous adhesive bond are brought into contact again.
