Abstract
Sound absorptive fiberglass pads within a silencer device for a centrifugal compressor are precompressed while installing the device in a containing frame mounted in the discharge pipe by a process including the steps of establishing the transverse dimension of the frame as a function of the transverse thickness of the device, precompressing one end of the device to a thickness which allows its insertion into the frame, and then forcing the entire device into the cavity in a wedgelike manner to thereby precompress the entire device, to thereby precompress the absorptive pad to a desired degree for purposes of erosion prevention.
