Is the phenol medium pipeline the GC1 pipeline?

Thread Content

According to HG/T20660, the toxicity of phenol as a medium is classified as Grade II. Therefore, should pipes using phenol as a medium be classified as GC1 pipes during the classification of pressure pipes?

Extreme hazard is what constitutes GC1; for phenol, it is GC2 when the pressure and temperature are not high.
