Why does the pipe downstream of the throttle orifice plate need to be enlarged?
Thread Content
I would like to ask the experts: I’ve seen many adsorption dryers, such as compression heat adsorption dryers, in which there is a section with a changed diameter right after the throttle orifice plate, before it connects to the main pipeline. For example, for a throttle orifice plate of DN40 size, there is a fitting with dimensions DN80*DN40 after it, or it directly connects to a DN80 pipeline before joining the main pipeline. Why does the pipeline need to have an enlarged diameter after the throttle orifice plate? What will be the consequences of not expanding it to connect directly to the main pipe?
Since the orifice plate was ordered incorrectly and I don’t want to return it, I’ll just make do with it
Not really; I’ve seen many desiccators connected in this way. I just don’t know why to do this
The diameter expansion here mainly serves to reduce speed and expand pressure (stabilize pressure)~~
