A axially split casing with flange connection of two casing halves, wherein the casing upper part (1) is bolted to the casing lower part (2) with split line bolts (5) on the circumference of the axial split line flange (3). An axially divided casing extension (9), which is surrounded by a coaxially arranged axially unsplit ring (11) on the outer circumference, is arranged at one or both end faces (4) of the casing upper part (1) and the casing lower part (2) in the area of the casing axis (8). Wedge-shaped tensioning elements (14), which are tensioned by means of tension bolts (15) between surfaces (13) arranged in the ring (11) and countersurfaces (12) of the collar (10) of the casing extension (9), may be additionally arranged between surfaces (12, 13) arranged in the ring (11) and the collar (10) of the casing extension (9).

Combined connection for axially split casings

The present invention pertains to a tubular heat exchanger for operation at high gas temperature and high pressures with heat exchanger tubes, which are coiled on the greater section of their linear extension. Further, the tube bottoms have tie rods, which brace the tube bottoms. The tie rods (3) of a graduated circle (1a, 1b) are connected at several points in the longitudinal direction by rings (5) into a cage. The tie rods (3) are flattened (3a) in the area of the rings (5). The tubes arranged on the adjacent graduated circle are connected to one another in the coiled area (2a) by means of angular plates (4) in pairs in the area of the rings (5). The connection to the angular plates (4) is such that, the tube form a hollow-cylinder-shaped tube cage. At least three guiding plates (6, 6a) are arranged in each area of uncoiled tubes (2b).
