I can’t understand the annotations on the US standard drawings. Who can give some guidance?
Thread Content
This is about a US standard drawing in my possession; there are no other relevant documents available for comparison. There are many pipes, valves, and instruments inside, and the markings on them differ greatly from the national standards; they’re difficult to understand. I hope experienced experts can offer some guidance and explain the specific reasons and meanings behind these markings. Thank you! ! :handshake:handshake:handshake
Go and check the schematic diagram page for that project; it contains explanations of the pipeline codes. 3 days ago, it was the same post with similar content. What do these labels mean? Haichuan Chemical Industry Forum - https://bbs.hcbbs.com/thread-2407560-1-1.html

If you don’t understand either, please wait together for someone more knowledgeable to give guidance; stop talking!

Just by guessing the character, you’ve shown that your skill level is on par with mine. It’s a shame I don’t have as much courage as you do – I wouldn’t dare to guess things like that! ! Who gave you the courage? ? If you don’t understand, just say so; no one will laugh at those who don’t know something. Only those who pretend to know when they don’t deserve ridicule. Stop talking too; let’s wait together for an expert —— not an expert based on guesses
Then let’s wait together and see if anyone can help you within a week If you don’t ask for the necessary project materials, who else will happen to work on a similar project with you?
If you were my colleague, such words would be understandable, but this is a technical forum – it’s a desperate plea for help from me! I’m asking for help; I have no other options, so I turn to experts for direct technical assistance, not to ask who can provide me with the relevant information. I’m here for technical answers. Once again, aside from this drawing, I have nothing else – no other materials or sources. I can only ask for guidance from those who are more experienced. Technically speaking, please stop suggesting that I keep looking for more information; if I did have such things, why would I bother to ask you all for help?
To put it bluntly, that’s not an attitude of seeking advice with an open mind!
