Crude benzene mainly contains benzene, which is a highly hazardous substance; according to the regulations, \"Q235-B shall not be used for hazards of grades I and II.\" ——“GB150”4.2.3 (P8): Is it appropriate to use Q235-B? For atmospheric-pressure vessels, is it possible not to follow the 150 standard?
For highly hazardous media, the normal pressure standards do not apply; design must be carried out in accordance with GB150 or HG20583. Q235B cannot be used, while Q245R or Q345R can be selected
Benzene is carcinogenic, but it is not highly hazardous. Moderate hazard. Benzene storage tanks, especially the large ones with capacities of thousands of cubic meters, are often made of carbon steel. Measures such as improving airtightness can be taken to ensure safety.
Under the new regulations, benzene is classified as a highly toxic substance that poses an extreme threat.
SH3501-2011
This is a pipeline standard and not applicable to equipment.
This standard specifies explicitly that benzene is a highly hazardous toxic substance; see Appendix A on page 24 for details
