Emerson introduces silencer to guard staff

Emerson has introduced the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour functions, which presents noise reduction in compressible fluid service for improved employee safety, with no impact on course of move.

The modal attenuator from Emerson is a full-bore device offering 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, similar to management valves or other devices. pressure gauge 10 bar is installed downstream of these gadgets instead of a pipe spool piece, it generates no further pressure drop, and has no impression on process move.
Until now, all options have generated important pressure drop, decreased flow, and/or introduced obstructions. pressure gauge octa has led some users to put in acoustic insulation to pipe sections to reduce back noise, but this might be pricey and cumbersome to put in, and it does nothing to scale back inside piping noise. The modal attenuator addresses these and other issues with a drop-in resolution, enhancing worker safety and regulatory compliance, while reducing the risk of harm to downstream tools due to high noise levels inside to piping.
Leading purposes for the modal attenuator include these the place upstream course of flows are changed by management valves, strain reduction valves, pumps, compressors and different gadgets that generate noise. Many of those units have to be installed in lengths of piping with no move restrictions downstream, and the modal attenuator works nicely in these functions as a result of it introduces no such restrictions.
In addition, the modal attenuator doesn’t introduce an obstruction into the piping, so it could be used in purposes the place particulates are suspended in process flows, and/or the place pigging is required for cleansing and upkeep.
WhisperTube gadgets are supplied in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange scores of Class one hundred fifty, 300 and 600. Pressure scores match the flange rating sizes, and the utmost temperature is 700°F (371° C).
