Emerson introduces silencer to protect workers

Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour functions, which provides noise reduction in compressible fluid service for improved employee safety, with no influence on course of flow.

The modal attenuator from Emerson is a full-bore system offering 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, corresponding to management valves or other gadgets. It is put in downstream of these gadgets rather than a pipe spool piece, it generates no extra strain drop, and has no influence on process move.
Until now, all options have generated significant strain drop, lowered move, and/or launched obstructions. This has led some customers to install acoustic insulation to pipe sections to cut back noise, but this might be expensive and cumbersome to put in, and it does nothing to reduce inner piping noise. The modal attenuator addresses these and different issues with a drop-in answer, improving worker security and regulatory compliance, whereas lowering the chance of damage to downstream gear because of excessive noise levels inside to piping.
Leading purposes for the modal attenuator embody these where upstream process flows are changed by management valves, strain reduction valves, pumps, compressors and other units that generate noise. Many of those devices must be put in in lengths of piping with no circulate restrictions downstream, and the modal attenuator works properly in these functions because it introduces no such restrictions.
In addition, the modal attenuator doesn’t introduce an obstruction into the piping, so it can be utilized in functions the place particulates are suspended in process flows, and/or where pigging is required for cleaning and maintenance.
WhisperTube gadgets are supplied in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class one hundred fifty, 300 and 600. เกจวัดแรงดันsumo match the flange score sizes, and the maximum temperature is 700°F (371° C).
