Emerson introduces silencer to guard workers

Emerson has introduced the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour functions, which provides noise discount in compressible fluid service for improved employee security, with no impression on process circulate.

The modal attenuator from Emerson is a full-bore gadget providing 15-decibel sound suppression to reduce noise inside pipes produced by sources upstream, similar to management valves or other devices. It is put in downstream of these gadgets instead of a pipe spool piece, it generates no extra stress drop, and has no impression on course of circulate.
Until now, all solutions have generated important strain drop, reduced flow, and/or launched obstructions. This has led some users to put in acoustic insulation to pipe sections to scale back noise, but this could be pricey and cumbersome to install, and it does nothing to cut back inner piping noise. The modal attenuator addresses these and different issues with a drop-in solution, improving employee safety and regulatory compliance, whereas reducing the risk of damage to downstream equipment as a result of excessive noise ranges inside to piping.
Leading functions for the modal attenuator embody those the place upstream process flows are modified by management valves, strain reduction valves, pumps, compressors and different units that generate noise. Many of these gadgets must be put in in lengths of piping with no move 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 applications the place particulates are suspended in process flows, and/or the place pigging is required for cleaning and maintenance.
เกจวัดแรงดันไนโตรเจนราคา 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 rankings match the flange ranking sizes, and the utmost temperature is 700°F (371° C).
