The modal attenuator from Emerson is a full-bore system offering 15-decibel sound suppression to reduce back noise inside pipes produced by sources upstream, such as management valves or other gadgets. It is installed downstream of these gadgets in place of a pipe spool piece, it generates no extra strain drop, and has no impression on process flow.
Until now, all solutions have generated vital pressure drop, reduced flow, and/or introduced obstructions. This has led some customers to install acoustic insulation to pipe sections to reduce noise, but this can be costly 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 solution, improving employee security and regulatory compliance, while reducing the risk of injury to downstream equipment because of high noise ranges internal to piping.
Leading purposes for the modal attenuator include those where upstream course of flows are changed by control valves, stress aid valves, pumps, compressors and other units that generate noise. Many of these devices must be put in in lengths of piping with no move restrictions downstream, and the modal attenuator works nicely in these applications as a end result of it introduces no such restrictions.
In addition, the modal attenuator doesn’t introduce an obstruction into the piping, so it can be used in functions where particulates are suspended in process flows, and/or the place pigging is required for cleansing and upkeep.
WhisperTube gadgets are supplied in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class a hundred and fifty, 300 and 600. เกจวัดแรงดัน10bar match the flange score sizes, and the utmost temperature is 700°F (371° C).
