Emerson introduces silencer to protect staff

Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour functions, which offers noise discount in compressible fluid service for improved worker security, with no impression on course of move.

The modal attenuator from Emerson is a full-bore device providing 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, similar to control valves or other devices. It is put in downstream of those gadgets in place of a pipe spool piece, it generates no additional pressure drop, and has no impression on course of circulate.
Until now, all solutions have generated vital stress drop, lowered circulate, and/or launched obstructions. This has led some customers to put in acoustic insulation to pipe sections to scale back noise, however this can be pricey and cumbersome to install, and it does nothing to cut back inside piping noise. The modal attenuator addresses these and other points with a drop-in resolution, bettering worker safety and regulatory compliance, whereas lowering the risk of injury to downstream equipment because of high noise ranges inside to piping.
Leading purposes for the modal attenuator embody these where upstream course of flows are modified by management valves, pressure aid valves, pumps, compressors and different gadgets that generate noise. Many of these units must be installed in lengths of piping with no move restrictions downstream, and the modal attenuator works properly in these applications as a result 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 purposes the place particulates are suspended in course of flows, and/or where pigging is required for cleaning and maintenance.
WhisperTube units are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class a hundred and fifty, 300 and 600. ร้านซ่อมเครื่องวัดความดันโลหิต match the flange ranking sizes, and the utmost temperature is 700°F (371° C).
