Simple calculation of the wall thickness of a negative-pressure cylinder
Thread Content
I’m not from a mechanical engineering background and am seeking help here: Dimensions are φ4400×13000; operating pressure: -3000 Pa; operating temperature: 105°C; material: Q235B. How can I simply calculate its wall thickness? Installation environment: The bottom 7 meters are indoors, while the upper 6 meters are above the roof top (at a height of 30 meters from the ground); the basic wind pressure is 0.7 kPa
Corrosion allowance of 2mm – is 12mm thickness acceptable?
After calculating, 8 mm thickness is just right, and 12 mm thickness is also fine
First, determine the wall thickness and calculation length, and calculate its stability
After calculation, when the corrosion allowance is 2 mm, the minimum thickness is 8 mm; it is advisable to use 10 mm as a safety margin.
