Steam safety valve outlet pipe
Thread Content
This question. See: https://wenku.baidu.com/view/12fd5653f01dc281e53af022.html In this article, the pressure in the outlet pipe of the steam safety valve is still 0.3 MPa gauge. That’s where the problem lies. Generally, export pipelines are classified as non-pressure pipelines. . . . Please, those who know something should talk.
It’s not a pressure pipeline – are you planning for a pressure lower than 0.1 MPag?

Let’s rephrase the question: I would like to know what the operating temperature and pressure, as well as the design temperature and pressure, are for the outlet pipeline of your steam safety valves Just use steam at a certain level.
The original link is no longer valid. I understand that the pressure at the outlet of the safety valve will be lower than the pressure at the inlet, but it usually doesn’t decrease by much. Considering the pressure loss in the drain pipe as well, the actual pressure loss is very small; therefore, the pipeline at the outlet of the safety valve should also be considered a pressure pipeline.
After all, the outlet pipeline of the safety valve is short; the outlet pipe of the safety valve is of the same grade as or slightly lower than the inlet pipe, so the cost is not high, and it’s safe；
The document cannot be opened. How long is the outlet pipe? Is it too long? After all, it leads to a discharge point
