ABSTRACT:
This invention is directed to a composite pipe comprising three layers adjacent to one another. It consists of a thin-walled metallic inner liner, a thermally insulating ceramic material layer, and an outer casing of a non-metallic material. The composite pipe is useful in automotive applications such as exhaust gas systems to reduce the thermal energy transfer from the exhaust pipe along the length of the pipe, reduce sound transmission, hinder corrosion and reduce weight.
