ABSTRACT:
The invention refers to a process and an arrangement to connect and seal tubes (2, 4) made of glass, metal or ceramic materials, that are joined to form flue-gas pipes. The sealing system according to the invention is distinguished by the fact that it can be used for exhaust gas pipes as well as for diminished cross-sections for chimneys, for example, since the sealing material is used in such a way that the overlapping pipes (2, 4) are connected in gas-tight manner even in the case of varying pressure conditions, and that the sealing material (8) is sufficiently resistant to acid, water and temperature to be used in the removal of hot, acid gases. In a preferred form of construction, the pipes (2, 4) are fixed together before applying the anorganic sealing material (8). The pipes are either fixed by punctually applied, quick-setting adhesive (6) or secured together by a pipe clamp (14) attached at the circumference of the pipes.
