What are the latest versions of the standards for construction drawing design? Including flanges, valves, pipes, pipe fittings, pipe racks, and so on... It would be great if an electronic version could be provided, haha(*^__^*) Hehe……
There are countless standards; the original poster should list them first, and others can add to them
The main standard for chemical engineering construction drawings is still HG20519-93; it has not been updated yet
The standard commonly used for chemical process pipe racks is HG/T21629-1999
The flange is in accordance with HG/T 20592-2009
The flange is from the 2009 version; I’m not sure about the rest
The unified specification HG20519 regarding the depth of design for chemical process construction drawings now has its latest 2009 version; meanwhile, the design specification HG20546 for the layout of chemical equipment also has a 2009 version, and both will come into effect on June 1 this year.
Who has the 2009 version of the regulations on the level of detail required for construction drawings, HG20519? Please share it, so I can study it
