Abstract
Method at joining of insulated pipes (1), which comprise an outer casing (2), and inner pipe (3) and a heat insulating material (4) placed between the outer casing (2) and the inner pipe (3). The end section (5) of the inner pipe projects a certain length in the end regions of the pipes (1) intended for the joining outside the end surface (11) of the heat insulating material and the end surface (12) of the outer casing. On one of the two pipes (1) to be joined a tubular mantle (6) surrounding the outer casing (2) has been applied, the length of said mantle being greater than the total projecting length of the inner pipes (3). In this phase the mantle (6) is moved along one pipe (1) so that the joining area is entirely uncovered. The projecting inner pipes (3) are then connected with each other. The next step is that the inner pipes (3) now joined are heated to working temperature after which two pipe sectors (20, 21) are placed in the joining area after applying an adhesive expanding at curing. The pipe sectors (20, 21) are preferably prefabricated and made of a heat insulating material. The best joining result is obtained if all the outer surfaces of the pipe sectors (20, 21) make contact with said adhesive. Moreover, adhesive is applied to the outer surfaces of the outer casings (2) in a region adjacent their end surfaces (12), after which the tubular mantle (6) is moved along the pipe (1) so that the mantle will enclose the pipe sectors (20, 21) and make contact with the outer casing (2) on both sides of said pipe sectors. The invention also relates to the device at the joining of said insulated pipes.
