Some issues regarding the latest version of the standard pipe rack drawings HGT21629-2021
Thread Content
Taking diagrams as an example, regarding components, the H value in the old standards represents the maximum value, but this is not the case in the new standards; so does this value represent a fixed value or the maximum value? If it represents the maximum value, then why is the subsequent L size also expressed as the maximum value? Secondly, for the height of other pipe racks, MAX H is also used to represent it. From my personal perspective, it makes sense to use the maximum value; after all, the heights differ by 1 meter, 2 meters, or 3 meters. Doing this in reality would be too costly, and it might also not look good.

I didn’t understand the examples of pipe rack labeling under the new standard; I felt that the numbering method specified in the \"Content and Depth Requirements\" was not scientific.
