Emerson introduces silencer to protect employees

Emerson has introduced the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour functions, which provides noise discount in compressible fluid service for improved employee safety, with no impression on course of move.

The modal attenuator from Emerson is a full-bore gadget providing 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, similar to control valves or other units. It is installed downstream of these gadgets in place of a pipe spool piece, it generates no extra strain drop, and has no influence on process move.
Until now, all solutions have generated important pressure drop, reduced flow, and/or introduced obstructions. This has led some customers to put in acoustic insulation to pipe sections to scale back noise, but this can be expensive and cumbersome to install, and it does nothing to reduce back inside piping noise. xp2i addresses these and different points with a drop-in answer, enhancing worker safety and regulatory compliance, while reducing the danger of damage to downstream gear as a end result of excessive noise levels inner to piping.
Leading purposes for the modal attenuator embody these where upstream process flows are changed by management valves, pressure aid valves, pumps, compressors and other units that generate noise. Many of these gadgets must be put in in lengths of piping with no flow restrictions downstream, and the modal attenuator works properly 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 can be used in functions the place particulates are suspended in process flows, and/or the place 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 scores of Class one hundred fifty, 300 and 600. Pressure scores match the flange ranking sizes, and the utmost temperature is 700°F (371° C).
