Meaning of codes in pipeline layout diagrams
Thread Content
Question: When looking at pipe layout diagrams, there are many codes that I don’t understand. Those who have relevant information could please help
It seems like the post is repeated. I’m not from a design field, so I suggest you check the legend first
The problem is that I’m coming to ask for advice because there are no diagrams
Generally, there should be a cover image; different units draw the same types of fittings in slightly different ways. If there is really nothing to refer to, then rely on your own understanding (these regulations are generally available on forums). HG 20519-92: Unified Regulations on the Content and Level of Detail for Construction Drawings in Chemical Process Design ； SH3052-2004T: Symbols for the design of piping systems in petrochemical industries, etc. For reference only
If it is a single-line diagram or axial view generated by PDS, and the names are in English instead of Chinese, it can indeed be difficult to understand if one has no prior experience with it. “HG 20519-92 Unified Specifications for the Content and Level of Detail in Construction Drawings for Chemical Process Design ； There is no “SH3052-2004T Petroleum and Chemical Pipeline Engineering Design Legend”.
There is a book on the forum titled \"Illustrated Glossary of English-Chinese Chemical Engineering Terms\"; take a look at it – it’s very intuitive. http://bbs.hcbbs.com/viewthread.php?tid=7447
Find the homepage image of a project and compare it with the process flow diagram and piping diagrams – it’s easy to get started!
Post the parts you don’t understand, and let’s see if we can help you
