Emerson introduces silencer to guard workers

เกจวัดแรงดันน้ำประปาราคา has launched the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour functions, which presents noise reduction in compressible fluid service for improved worker safety, with no influence on course of circulate.

The modal attenuator from Emerson is a full-bore device providing 15-decibel sound suppression to reduce back noise inside pipes produced by sources upstream, corresponding to management valves or other units. It is installed downstream of those gadgets instead of a pipe spool piece, it generates no further pressure drop, and has no influence on course of move.
Until now, all options have generated significant strain drop, lowered move, and/or launched obstructions. This has led some users to install acoustic insulation to pipe sections to reduce noise, however this can be pricey and cumbersome to put in, and it does nothing to reduce internal piping noise. The modal attenuator addresses these and different points with a drop-in solution, enhancing employee safety and regulatory compliance, while lowering the danger of injury to downstream gear as a outcome of high noise ranges inner to piping.
Leading applications for the modal attenuator embrace these where upstream process flows are modified by management valves, pressure relief valves, pumps, compressors and different gadgets that generate noise. Many of those devices should be installed in lengths of piping with no circulate restrictions downstream, and the modal attenuator works well in these applications as a outcome 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 applications where particulates are suspended in process flows, and/or where pigging is required for cleansing and upkeep.
WhisperTube gadgets are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class one hundred fifty, 300 and 600. Pressure scores match the flange ranking sizes, and the maximum temperature is 700°F (371° C).
