Emerson introduces silencer to guard staff

Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy gas or vapour applications, which provides noise reduction in compressible fluid service for improved employee safety, with no impact on process move.

The modal attenuator from Emerson is a full-bore device providing 15-decibel sound suppression to minimize back noise inside pipes produced by sources upstream, similar to control valves or other devices. It is put in downstream of those devices in place of a pipe spool piece, it generates no extra pressure drop, and has no impact on process circulate.
Until now, all options have generated important stress drop, lowered flow, and/or introduced obstructions. This has led some users to put in acoustic insulation to pipe sections to scale back noise, but this may be expensive and cumbersome to put in, and it does nothing to scale back inner piping noise. The modal attenuator addresses these and different issues with a drop-in answer, bettering worker safety and regulatory compliance, while reducing the danger of injury to downstream gear because of high noise ranges inside to piping.
Leading purposes for the modal attenuator embody these the place upstream course of flows are changed by control valves, pressure reduction valves, pumps, compressors and other gadgets that generate noise. Many of these units should be installed in lengths of piping with no flow 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 can be utilized in purposes where particulates are suspended in process flows, and/or the place pigging is required for cleansing and maintenance.
เกจวัดแรงดันอากาศ are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class 150, 300 and 600. Pressure rankings match the flange ranking sizes, and the utmost temperature is 700°F (371° C).
