Abstract
A connection assembly for joining two parts having confronting ends with a joint therebetween, particularly ceramic pipes, includes a dimensionally stable coupling member surrounding the joint and at least one of the two confronting ends of the two parts to be joined. The coupling member is dimensioned to define a space with the at least one part end. This space is filled with a ceramic fiber mat material containing a swelling agent capable of volume expansion when subjected to a temperature above a given minimum temperature. As a result, upon being subjected to an operating temperature above such given temperature, the swelling agent swells the ceramic fiber mat material, such that the mat material is compressed between the coupling member and the at least one part end surrounded thereby, thereby connecting the two parts.
