Emerson introduces silencer to guard staff

เกจ์วัดแรงดันน้ำ has introduced the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour functions, which presents noise discount in compressible fluid service for improved employee security, with no influence on course of flow.

The modal attenuator from Emerson is a full-bore gadget providing 15-decibel sound suppression to reduce back noise inside pipes produced by sources upstream, corresponding to control valves or different devices. It is installed downstream of those gadgets rather than a pipe spool piece, it generates no further stress drop, and has no impact on course of flow.
Until now, all solutions have generated vital strain drop, lowered circulate, and/or launched obstructions. เกจวัดแรงดันสูง has led some customers to put in acoustic insulation to pipe sections to reduce back noise, however this can be expensive and cumbersome to put in, and it does nothing to scale back internal piping noise. The modal attenuator addresses these and other points with a drop-in resolution, bettering employee safety and regulatory compliance, whereas decreasing the chance of injury to downstream gear due to excessive noise levels inside to piping.
Leading applications for the modal attenuator embody these the place upstream process flows are changed by control valves, pressure relief valves, pumps, compressors and other units that generate noise. Many of those units should be installed in lengths of piping with no move restrictions downstream, and the modal attenuator works well in these functions because it introduces no such restrictions.
In addition, the modal attenuator doesn’t introduce an obstruction into the piping, so it may be utilized in purposes where 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 ratings of Class a hundred and fifty, 300 and 600. Pressure rankings match the flange score sizes, and the utmost temperature is 700°F (371° C).
