Method and device for centering and temporary fixation of tube parts (1, 5) in relation to each other's interior surfaces, comprising a first tool (9) which is centered relative to a tube part interior surface (2, 6) by centering means (13), which are radially adjustable. The centering means (13) of the first tool (9) are insertable in the tube part (1, 5). Characterizing is that a second tool (10) is centered relative to the first tool (9), by guiding means (15) which cooperates for centering of the tools (9, 10) relative to each other. Further, the second tool comprises fixing means (17) to fix the exterior surface (3, 7) of the tube part (1, 5) to the second tool (10), and at least one third guide (18) which centers two such second tools (10) relative to each other in their mounted position on respective tube part end (4, 8) and at least one coupling member (19) to connect the two second tools (10). |
