Regarding the \"flammable liquids\" mentioned in the definition of pressure pipelines, is there any requirement regarding their flash point?
Thread Content
In my personal opinion, flammable liquids mainly refer to Category A and B liquids, as well as liquids whose operating temperature is above their flash point； At room temperature, Category C A and Category C B should not fall into this category; what’s everyone’s understanding of this?
In the general provisions of GB20801.1-2020, Appendix A clearly states that Class C A and Class C B are considered flammable liquids
