Calculation of orifice plates in steam vent lines
Thread Content
The discharge pressure of the safety valve on the main steam pipe is 0.64 MPaG, and the steam flow velocity in the pipeline leading out from the safety valve is 78 m/s. Is it necessary to install an orifice plate in this pipeline to reduce noise? Additionally, what is the calculation method for the noise-reducing orifice plates on vent pipelines?
It shouldn’t be for reducing noise; silencers are what are used to reduce noise. The orifice plates on the vent pipes in the piping system are likely there to reduce pressure
How can an orifice plate be installed on the outlet pipeline of a safety valve? This way, it cannot serve the purpose of pressure relief for safety.
@It’s high-end, stylish, and of top quality. Could the teacher give some guidance? Thank you!
I calculated the secondary steam orifice plate according to HG20570, but I feel there are some issues.

For steam venting, we don’t have any orifice plates; if any exist, they are silencers.
Follow what the experts upstairs said about using a silencer; I’ve never seen a perforated plate being used in this context
