Pipe connection for flue-gas pipes

A pipe connection for flue-gas pipes comprising:

• a first pipe having an end portion;
• a second pipe having a smooth end portion, said end portion of said first pipe overlapping said smooth end of said second pipe;
• a gap formed from the overlap of said first pipe and said second pipe, said gap including an annular region and extending in an axial direction;
• and
• an anorganic sealing mass filling said gap, partially in said axial direction and completely in said annular region;
• wherein said first pipe and said second pipe are fixed together by fixing means;
• and
• wherein said sealing mass is a chemically setting mineral sealing mass having a thermal expansion factor in the range of 3.3 to 12.times.10.sup.-6 K.sup.-1.

• a second pipe having a smooth end portion, said end portion of said first pipe overlapping said smooth end of said second pipe;
• a gap formed from the overlap of said first pipe and said second pipe, said gap including an annular region and extending in an axial direction;
• and
• an anorganic sealing mass filling said gap, partially in said axial direction and completely in said annular region;
• wherein said first pipe and said second pipe are fixed together by fixing means;
• and
• further comprising a device provided in said gap so as to form a cavity defined by the device, an inner surface of said first pipe and an outer surface of said second pipe, said device providing a surface whereby condensation drips into the interior of the pipe connection.
