Abstract
A sealing system, in particular for sealing multiple part exhaust-gas lines for an internal combustion engine, has at least a first flange part () and a second flange part () guiding a flow of heat (). The flange parts () delimit a receiving space () for at least one sealing element () between them and adjoin one another. Each flange part forms an outwardly projecting annular flange () facing away from the flow of heat (), and extending transversely with respect to the heat flow. Chambering of the receiving space () is formed for the sealing element () by an annular groove () open at the end face () of at least one flange part () and recessed axially into said end face (). At least one covering element () is arranged in the annular groove () and provides thermal shielding for the sealing element () at least on its side facing the end face () of the flange part ().
