Emerson introduces silencer to protect staff

Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour purposes, which presents noise reduction in compressible fluid service for improved worker security, with no impact on process flow.

The modal attenuator from Emerson is a full-bore gadget providing 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, similar to management valves or other gadgets. It is put in downstream of these gadgets instead of a pipe spool piece, it generates no extra stress drop, and has no impression on process circulate.
Until now, all options have generated vital pressure drop, decreased move, and/or launched obstructions. This has led some users to install acoustic insulation to pipe sections to reduce noise, however this can be expensive and cumbersome to put in, and it does nothing to scale back inside piping noise. The modal attenuator addresses these and different points with a drop-in resolution, bettering worker security and regulatory compliance, whereas lowering the chance of harm to downstream gear due to high noise ranges inner to piping.
Leading purposes for the modal attenuator embrace those the place upstream process flows are modified by control valves, stress reduction valves, pumps, compressors and different gadgets that generate noise. Many of those units should be put in in lengths of piping with no circulate restrictions downstream, and the modal attenuator works properly in these purposes as a outcome of it introduces no such restrictions.
In addition, the modal attenuator doesn’t introduce an obstruction into the piping, so it may be used in applications where particulates are suspended in process flows, and/or where pigging is required for cleansing and maintenance.
WhisperTube devices are supplied in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange scores of Class 150, 300 and 600. Pressure ratings match the flange rating sizes, and the maximum temperature is 700°F (371° C).
