Emerson introduces silencer to guard staff

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

The modal attenuator from Emerson is a full-bore gadget offering 15-decibel sound suppression to reduce noise inside pipes produced by sources upstream, such as control valves or other devices. It is put in downstream of these devices in place of a pipe spool piece, it generates no additional pressure drop, and has no impact on course of circulate.
Until now, all solutions have generated significant stress drop, decreased circulate, and/or launched obstructions. เกจวัดแรงดันน้ำมันเครื่อง has led some customers to put in acoustic insulation to pipe sections to cut back noise, however this could be costly and cumbersome to install, and it does nothing to scale back inner piping noise. The modal attenuator addresses these and different points with a drop-in answer, improving worker safety and regulatory compliance, while decreasing the chance of injury to downstream equipment due to high noise levels inner to piping.
Leading purposes for the modal attenuator include these the place upstream process flows are modified by control valves, pressure relief valves, pumps, compressors and different gadgets that generate noise. Many of these devices should be put in in lengths of piping with no move restrictions downstream, and the modal attenuator works well in these purposes as a result of it introduces no such restrictions.
In addition, the modal attenuator does not introduce an obstruction into the piping, so it might be utilized in applications the place particulates are suspended in process flows, and/or where pigging is required for cleaning and upkeep.
WhisperTube gadgets are offered in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange scores of Class one hundred fifty, 300 and 600. Pressure ratings match the flange score sizes, and the utmost temperature is 700°F (371° C).
