DN25 and DN40 are not pressure pipelines; can pipelines that comply with GBT8163 be used for PN100?

As the title suggests, DN25 and DN40 are not pressure pipelines; for PN100, can pipes in accordance with GBT8163 be used?
Is this question not described clearly?
The description is incorrect. The selection of pipeline manufacturing standards is not related to pressure pipelines; rather, it is determined based on the medium, temperature, and pressure. The conditions you provided are useless; it seems you want to use GB8163 as a substitute for higher standards such as GB9948
It mainly depends on the medium and temperature, taking all factors into consideration
For PD100, it’s better not to use GB/T8163; using it will only cause trouble.
A misconception: Pipes that are not within the scope of inspection are not pressure pipes! ! ! !
It depends on the properties of the medium; ordinary ones will work
PN100 pipes are no longer ordinary fluid pipelines; they are not suitable for 8163. Grade A+ materials should be used instead.
Considering the medium, pressure, and temperature, it is recommended to opt for higher standards whenever financial conditions permit
The philosophy is changing, from speed, efficiency, and cost savings to long-term stability
