What conditions should pipes that are not shown in the layout meet?

It seems that the power industry has such regulations, but I haven’t been able to find them. For the boiler feed pipe, it’s 89*4 with a design temperature of 140; for the saturated steam pipe, it’s 57*3 with a design temperature of 180. The waste gas pipe is 108*4 with a design temperature of 210, while another waste gas pipe is 89*4 with a design temperature of 210, and yet another one is 57*3 with a design temperature of 210. Is it possible to avoid providing layout diagrams for these?
The standard is unknown. It seems that pipes under 2" won’t be included in the drawings, right?
