The invention relates to an insulation pipe system comprising insulated piping components, such as insulation pipes (1, 2), fire dampers, dampers, measurement connections and branch tubings, said pipe component comprising an inner pipe (3), an outer pipe (4) and a space between them for insulation material (5). In order that ventilation systems and the like complying with the fire-resistance grading and the provisions could be easily and rapidly accomplished and the amount of work to be done in situ could be minimized, both ends of the piping component are provided with an end flange (6) which substantially covers the space between the inner and outer pipe and which, by being connected to the inner pipe (3) and the outer pipe (4), centers the inner pipe with respect to the outer pipe, said end flange being connected indirectly through its outer circumference (7) to the outer pipe in such a manner that it is fixed to an insulation ring (8) provided in connection with a flange ring (9) on the circumference of the outer pipe so that the end flange is not in direct contact with the outer casing of the piping component. |
