Emerson introduces silencer to guard workers

Emerson has introduced the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour applications, which presents noise reduction in compressible fluid service for improved employee security, with no impression on course of flow.

The modal attenuator from Emerson is a full-bore device providing 15-decibel sound suppression to reduce noise inside pipes produced by sources upstream, such as management valves or other devices. It is installed downstream of those units instead of a pipe spool piece, it generates no additional strain drop, and has no impression on process circulate.
Until now, all options have generated vital stress drop, reduced flow, and/or launched obstructions. This has led some customers to put in acoustic insulation to pipe sections to cut back noise, however this can be pricey and cumbersome to put in, and it does nothing to reduce back inside piping noise. เกจ์วัดแรงดัน addresses these and other issues with a drop-in solution, improving worker security and regulatory compliance, while lowering the risk of damage to downstream tools because of excessive noise ranges internal to piping.
Leading functions for the modal attenuator include those the place upstream course of flows are changed by control valves, pressure relief valves, pumps, compressors and other devices that generate noise. Many of those gadgets must be put in in lengths of piping with no flow restrictions downstream, and the modal attenuator works nicely in these purposes 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 functions the place particulates are suspended in course of flows, and/or the place pigging is required for cleansing and upkeep.
WhisperTube devices are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class a hundred and fifty, 300 and 600. Pressure scores match the flange score sizes, and the maximum temperature is 700°F (371° C).
