Emerson introduces silencer to protect staff

Emerson has introduced the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour applications, which presents noise reduction in compressible fluid service for improved worker security, with no impact on process move.

The modal attenuator from Emerson is a full-bore device offering 15-decibel sound suppression to reduce back noise inside pipes produced by sources upstream, such as management valves or other units. It is installed downstream of these gadgets in place of a pipe spool piece, it generates no further stress drop, and has no impression on course of flow.
Until now, all solutions have generated vital strain drop, reduced circulate, and/or introduced obstructions. This has led some customers to install acoustic insulation to pipe sections to scale back noise, however this might be expensive and cumbersome to put in, and it does nothing to reduce inside piping noise. The modal attenuator addresses these and different points with a drop-in answer, bettering worker security and regulatory compliance, while decreasing the chance of damage to downstream tools due to high noise ranges inside to piping.
Leading เกจวัดแรงดันแก๊สหุงต้ม for the modal attenuator include those the place upstream course of flows are changed by management valves, strain aid valves, pumps, compressors and different units that generate noise. เกจวัดแรงดัน of those devices have to be put in in lengths of piping with no move restrictions downstream, and the modal attenuator works well in these purposes as a outcome 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 where particulates are suspended in course of flows, and/or the place pigging is required for cleaning and maintenance.
WhisperTube units are offered in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange scores of Class a hundred and fifty, 300 and 600. Pressure rankings match the flange score sizes, and the maximum temperature is 700°F (371° C).
