I think I remember it being around 70 KPA! Can’t remember

1. If it is a cylindrical container with a volume greater than 500 L, a design temperature of ≤350°C, and a design pressure ranging from >-0.02 Mpa to

Atmospheric pressure vessels refer to vessels with a design pressure of less than 0.1 MPa. The applicable types of such vessels include: a) Cylindrical vessels: with a design pressure greater than –0.02 MPa and less than 0.1 MPa, and the design temperature range is determined based on the allowable operating temperature for the steel material used； b) Rectangular container: The design pressure is zero, and the design temperature range is determined based on the allowable operating temperature of the steel material.

For details, see JB/T4735-1997 \"Steel Welded Atmospheric Pressure Vessels\"~~

Then I would like to ask: to which category does a rectangular container designed for a pressure range of -0.5 to 2.7 kPa belong?
