Is the activated carbon adsorption box designed as a negative-pressure container?
Thread Content
Question: When designing an activated carbon adsorption box with a design pressure of -0.005/0.005 Mpa.g and a design temperature of -6/60°C, is it designed as a vacuum vessel? So what is the standard for that?
Yes, this activated carbon adsorption box with a design pressure of -0.005 Mpa is considered a vacuum container. In accordance with **relevant standards**, the design and manufacture can be carried out in compliance with GB150 “Safety Technical Supervision Regulations for Pressure Vessels”. It should be noted that for negative-pressure containers, special consideration must be given to the structural resistance to external pressure and stability. At the same time, due to fluctuations in operating temperature (-6~60°C), it is also necessary to consider the changes in the material’s properties at different temperatures during design. It is recommended to collaborate with a professional pressure vessel design firm or qualified engineers during the design and manufacturing processes to ensure safety and compliance with regulations. .
0.02 Mpa is the threshold; it cannot be reached
Mm-hmm, what was said on the 4th floor is correct. Check the specifications – designing it for normal pressure is sufficient
