May I ask if non-metallic pipes can be used for pressure pipelines? In other words, is there such a thing as pressure pipelines made of non-metallic materials?
Yes, the definition of pressure pipelines does not specify whether they are metal or non-metal pipes; it simply refers to pipelines.
Non-metallic pipes are not included in this scope
It should work; the pressure rating of the oxygen tube is very high, so it’s definitely correct
There’s no need to discuss this; it’s a given
According to the definition of pressure pipelines given in the 2014 announcement by the General Administration of Quality Supervision, Inspection and Quarantine regarding the revision of the \"Catalogue of Special Equipment\" (Document No. 114), pressure pipelines refer to pipe systems that use a certain pressure to transport gases or liquids. . . . . . . Non-metallic pipes are not excluded here, so they should be included in the calculation
Based on the definition of pressure pipelines, I agree with what was said on the 6th floor
The definition of pressure pipelines does not restrict them to metals or non-metals; in fact, non-metallic pipes are already used in urban pipeline systems. You can refer to the corresponding sections of GB50028, the Code for Design of Urban Gas Supply.
