How is the thickness of the pressure vessel steel plate determined
Rolling thickness + added value, this is based on the pressure value!
Pressure vessel steel thickness = calculate thickness + corrosion allowance + plate negative deviation + round value The calculation thickness meets the need for strength; The quantity of corrosion allowance for the use of life; The negative deviation of the steel plate meets the material standards; The above three items add up to the thickness of the nominal thickness of the equipment, which is the thickness of the drawing.
If the problem is simple, the volume of the container is determined by the pressure and the medium. Consider the necessary corrosion allowance and seismic action. The container board in the country mainly has Q345R, the performance parameters of different materials are different.
