Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour applications, which presents noise reduction in compressible fluid service for improved employee safety, with no impression on course of circulate.

The modal attenuator from Emerson is a full-bore system providing 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, such as management valves or different units. It is installed downstream of these gadgets in place of a pipe spool piece, it generates no further pressure drop, and has no impact on process circulate.
Until now, all options have generated significant pressure drop, reduced circulate, and/or introduced obstructions. This has led some customers to install acoustic insulation to pipe sections to scale back noise, but this can be costly and cumbersome to install, and it does nothing to scale back internal piping noise. ที่วัดแรงดันน้ำ addresses these and other issues with a drop-in resolution, bettering worker safety and regulatory compliance, while reducing the risk of damage to downstream tools as a end result of excessive noise levels internal to piping.
Leading applications for the modal attenuator embody those the place upstream process flows are changed by control valves, pressure reduction valves, pumps, compressors and other 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 nicely 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 could be used in purposes the place particulates are suspended in process flows, and/or the place pigging is required for cleaning and maintenance.
WhisperTube gadgets are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange ratings of Class a hundred and fifty, 300 and 600. Pressure scores match the flange ranking sizes, and the utmost temperature is 700°F (371° C).
