A pipe for an air-supply system of a burner system comprising:
- at least one of an inner pipe and an inner surface, the at least one of the inner pipe and the inner surface including at least one swelling element for changing an innermost diameter or an inner innermost cross-sectional surface of the pipe, the at least one swelling element having a volume that changes as a function of temperature and is being expandable radially inward to change the innermost diameter or the inner innermost cross-sectional surface of the pipe.
A pipe for an air-supply system of a burner system comprising:
- at least one of an inner pipe and an inner surface, the at one of the inner pipe and the inner surface including at least one element for changing an innermost diameter or an inner innermost cross-sectional surface of the pipe, the at least one element being configured to be expandable in response to a temperature increase to close and seal the pipe and prevent a return flow.
