Questions regarding pipeline naming
Thread Content
I have a question for everyone. As shown in the diagram, is the end point of tube number 2 tube number 1 or the reactor? In principle, shouldn’t each tube have only one identifier? If the end point of tube number 2 is R-101, then wouldn’t the orange line represent two different tube identifiers? Do P and C represent two different substances that do not react with each other?
The destination is number 1. Remember to take a proper photo next time
According to the description in the diagram, the end point of Tube No. 2 should be Reactor R-101. In the process of industrial production, due to the complexity of pipeline networks, in order to manage and maintain them more effectively, each pipeline is usually numbered, with the number marked at both ends of the pipeline. However, in practice, it is possible for multiple pipelines to share the same section of pipe; in such cases, different identifiers can be added to distinguish between them, such as using P and C to differentiate between two different substances. This does not violate any principles, as long as the information about the pipeline can be expressed clearly and precisely. .
