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 worker safety, with no impression on course of circulate.

The modal attenuator from Emerson is a full-bore gadget offering 15-decibel sound suppression to reduce noise inside pipes produced by sources upstream, similar to control valves or other devices. It is put in downstream of those devices in place of a pipe spool piece, it generates no additional strain drop, and has no impact on process circulate.
Until now, all options have generated important stress drop, reduced flow, and/or launched obstructions. This has led some users to install acoustic insulation to pipe sections to scale back noise, however this might be expensive and cumbersome to put in, and it does nothing to reduce back inner piping noise. The modal attenuator addresses these and different issues with a drop-in resolution, enhancing employee security and regulatory compliance, whereas lowering the risk of injury to downstream equipment due to excessive noise ranges inside to piping.
Leading purposes for the modal attenuator embrace these where upstream process flows are changed by management valves, strain relief valves, pumps, compressors and different units that generate noise. เกจวัดแรงดันน้ำดิจิตอล of these devices must be installed in lengths of piping with no move restrictions downstream, and the modal attenuator works nicely 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 might be used in purposes where particulates are suspended in process flows, and/or where pigging is required for cleaning and upkeep.
WhisperTube units 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 score sizes, and the utmost temperature is 700°F (371° C).
