  • the outer shell 3 consists of a first half-shell 14 and a second half-shell 15, the edges thereof at seams 18, 19, 20 and 21 abut each other and welded together. This extends the first seam 18 between the input flanges 10 and 11, the second seam 19 between the input flanges 11 and 12, the third seam 20 follows at a radial distance the contour of the connecting piece 8 between the input flange 12 and the output flange 5 and the fourth seam 21 extends at a radial distance of the inner tube 2 from the input flange 10 to the output flange 5. As can be seen from Fig.
  • a box shape of the outer shell results 3, in which the distance of the outer shell to the inner tube 2 in the area between the seams 18, 19 and the inner tube 2 is substantially larger than that Distance of the seams 20, 21 to the inner tube 2.
  • the inner tube 2 forming pieces 6, 7, 8 are in the openings the input flanges 10, 11, 12 and the output flange 5 recorded.
  • the edges of the outer shell 3 can be welded into the openings of the flanges or immediately in front of the entrance flanges welded to the inner tube. To this The result is a closed space 4 for air gap insulation.
  • Fig. 2 shows a section along the line II-II in Fig. 1, wherein for reasons of clarity the representation of the input flange and in this introduced end of the elbow was omitted. From Fig. 2 it can be seen that the first half-shell 14 and the second half-shell 15 bent outward Edges 22, 22 'and 23, 23', in which the Half shells 14 and 15 mirror-symmetrically to each other lie. The edges 22, 23 and 22 ', 23' are interconnected welded and due to the shape of the edges are the Seams 18, 21 formed as flanged seams. Likewise the seams of the outer shell, not shown in Fig. 2 3 the shape of flanged seams on.
