เกวัดแรงดัน has introduced the Fisher WhisperTube Modal Attenuator for noisy gas or vapour functions, which offers noise reduction in compressible fluid service for improved employee safety, with no impression on process move.

The modal attenuator from Emerson is a full-bore device providing 15-decibel sound suppression to reduce noise inside pipes produced by sources upstream, corresponding to control valves or other devices. It is put in downstream of those units rather than a pipe spool piece, it generates no extra strain drop, and has no influence on course of move.
Until now, all solutions have generated important stress drop, reduced move, and/or introduced obstructions. This has led some customers to put in acoustic insulation to pipe sections to scale back noise, however this may be pricey and cumbersome to install, and it does nothing to scale back inner piping noise. ราคาเพรสเชอร์เกจ addresses these and other points with a drop-in answer, bettering employee security and regulatory compliance, whereas reducing the chance of injury to downstream tools as a end result of high noise ranges inner to piping.
Leading applications for the modal attenuator embody these the place upstream process flows are changed by management valves, strain reduction valves, pumps, compressors and different devices that generate noise. Many of these units must be put in in lengths of piping with no move restrictions downstream, and the modal attenuator works well in these applications because it introduces no such restrictions.
In addition, the modal attenuator does not introduce an obstruction into the piping, so it might be used in applications the place particulates are suspended in process flows, and/or the place pigging is required for cleansing and maintenance.
WhisperTube gadgets are offered in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange scores of Class one hundred fifty, 300 and 600. Pressure rankings match the flange rating sizes, and the utmost temperature is 700°F (371° C).
