This paper discusses gasket technology to address the increasing demands of providing effective sealing solutions for exhaust systems. Increasingly, effectively sealed joints are required in exhaust systems to meet environmental and emissions regulations. These applications are especially demanding for sealing. With low load joints, significant flange movement, and temperatures in excess of 850°C (1550°F), it is difficult for traditional gaskets to provide an effective seal, typically degrading or creeping at operating temperatures. Utilizing multi-layer steel gasket technology, this paper details a solution to these problems. Temperature stability and sealing data is presented demonstrating the superior performance of this material. Also presented is information from recent field experience.
