Abstract
This paper is an update on more recent work on the effectiveness of lining steel pipes and tubes with various polymer and ceramic materials to reduce impact noise emission. A paper was presented on this at the 1994 AAS conference in Canberra and described the effects of internal nylon lining of steel tubes used in steel plant run-out table. Data was also presented at the conference of the effects using ceramic material as a filler to dampen noise emission. Recent work has focused on external polyurethane lining and internal plastic foam lining on similar pipes and tubes. The tubes are commonly used as conveyor rollers in steel and industrial production plants. The reduction in sound levels for each different application system will be presented.
