Abstract
An acoustically isolated structure for use on a high temperature pipe in a luid environment is disclosed. Thermal insulation is provided radially outward from and adjacent to the pipe, and a sleeve is located on the outer surface of the insulation preventing environmental fluid from damaging the thermal insulation. A spacer is joined to the sleeve to position an acoustical barrier away from the pipe. The spacer allows environmental fluid circulation between the sleeve and the acoustical barrier.
