What does L1N in the pipe segment number mean?
Thread Content
In the pipe segment number specified on one of the drawings, for L1N, what does this N represent in terms of material? I checked the unified design regulations and there is no N.
Check the material specification sheet for this project, as well as the P&ID title page.
Please write down the entire pipeline number so that everyone can make a judgment
There will be an explanation in the image on the home page
The drawings produced by the design institute should come with legend explanations! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
L represents the nominal pressure rating code, 10 kilograms. As for 1N, without seeing the image on the homepage, no one knows what it is.
A different image on the home page implies a different meaning

It’s difficult for us to analyze this without a cover image or drawings; is it nitrogen at 1 Mpa? It’s hard to say; it depends on the purpose
The specific pipeline number is needed; otherwise, it’s difficult to determine
