Under what circumstances do chemical process pipelines need to have their diameter changed? ?
Thread Content
I was looking at a set of drawings recently and noticed that many low-temperature pipes running from lower to higher levels have changed in diameter? I don’t know why the diameter needs to be changed? Please have a lively discussion and provide your responses! Thank you!
I’m sorry; this post was originally meant to be posted in the Industrial Pipes section, but there was a mistake! ~It doesn’t matter really; let’s discuss it together! Please ask the administrator not to delete this post!
The choice of variable diameter is generally determined by the manufacturing process; the pipeline is used to enable the medium to meet the specified pressure and flow requirements
It is done to meet the process requirements
Could the person upstairs explain it in more detail?
The variable diameter is set to meet the requirements of the process flow rate
At points where pipes branch off, the flow rate changes due to the splitting or mixing of fluids; therefore, the pipes often need to have their diameter adjusted in order to maintain an optimal flow velocity. For fluids such as flammable and explosive liquids, hydrogen, and other substances for which the flow velocity is important, it is also necessary to take into account the maximum allowable flow velocity. The flow rates of commonly used fluids can be found in various chemical engineering handbooks.
Pipelines simply use this method to bring the medium to the specified pressure.
