ABSTRACT:
To seal a pipe mortar, a sealing element (3, 6) is inserted between the pipe (1) and the base (2), with the element elastically balancing out the axial relative movements between the pipe (1) and the base (2). The sealing element (3) is preferably prestressed, with the gas pressure supporting the sealing effect. The sealing element (3, 6) can be a U-shaped or L-shaped steel ring. In the U-shaped sealing element (3), the legs (3.1) are axially prestressed to the extent that the sealing ring (3) and the pipe (1) or the base (2) are pressed together to produce an adequate seal. In the L-shaped sealing element (6), the inside leg (6.1) produces the gas-tight connection when the pipe (1) and the base (2) are screwed together. A sealing lips (6.2) of the sealing ring (6) elastically absorbs changes in length between the pipe and the base that occur during firing.
