Emerson introduces silencer to protect staff

เกจวัดแรงดันแก๊สหุงต้ม has launched the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour purposes, which presents noise reduction in compressible fluid service for improved employee security, with no impact on course of move.

The modal attenuator from Emerson is a full-bore device offering 15-decibel sound suppression to reduce noise inside pipes produced by sources upstream, such as management valves or different units. It is installed downstream of these devices in place of a pipe spool piece, it generates no additional pressure drop, and has no influence on process flow.
Until now, all options have generated vital strain drop, reduced circulate, and/or introduced obstructions. This has led some customers to put in acoustic insulation to pipe sections to scale back noise, however this could be pricey and cumbersome to install, and it does nothing to minimize back internal piping noise. The modal attenuator addresses these and other points with a drop-in solution, enhancing employee security and regulatory compliance, while decreasing the chance of harm to downstream gear due to high noise ranges inside to piping.
Leading pressure gauge ไฮ ด รอ ลิ ค for the modal attenuator embrace these where upstream course of flows are modified by management valves, pressure relief valves, pumps, compressors and different devices that generate noise. Many of these units should be installed in lengths of piping with no move restrictions downstream, and the modal attenuator works nicely in these functions because it introduces no such restrictions.
In addition, the modal attenuator doesn’t introduce an obstruction into the piping, so it could be used in functions where particulates are suspended in process flows, and/or the place pigging is required for cleansing and maintenance.
WhisperTube units are supplied 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 scores match the flange rating sizes, and the maximum temperature is 700°F (371° C).
