If a non-metallic pipe is used for transporting Class A liquids, at normal temperature and with a pressure of over 0.1 MPA and a diameter of 80, does it count as a pressure pipe? Should it be classified as GC2 according to pressure pipeline standards? ? ?
The classification of pressure pipelines has nothing to do with the material used in the pipelines; it can be defined as GC2
In accordance with the regulatory requirements, if a non-metallic material meets the three definitions of pressure pipelines, it is considered a pressure pipeline.
