May I ask how pipes other than the pressure pipes – industrial pipes GC1, GC2, and GC3 – are managed? Are there any regulations for this?

We have high-pressure air pipes here, but their diameter is very small; they don’t qualify as pressure pipes. How should they be managed? We want to conduct regular inspections of the welds, and the management needs to provide guidance based on that
If it is not a pressure pipeline, there is no need to comply with the pressure pipeline regulations. Check the design documents from that time to see if there are any usage requirements. Factory control standards should be set independently.
The day before yesterday I went to the special inspection agency, and they told me that pressure air pipes under 150mm are not subject to special equipment regulations
