I would like to seek advice from the seniors regarding the volume of pressure vessels
Thread Content
I recently encountered a rather tricky task: I needed to design a tank in which water and air are the working media. The required volume is 75 cubic liters, but the client asked that the design drawings indicate a volume of 80 cubic liters. I was wondering whether it’s acceptable to state a volume of 80 cubic liters in such a case Are there any standards for calculating volume errors? First, thank you all, seniors.:)
That’s right; during the design phase, the actual product hasn’t been created yet, so it’s not possible to conduct actual measurements. One can only calculate the volume based on the drawings, and the drawings also need to specify the volume. In my case, I calculated the volume to be 75 cubic units. Can I write 80 cubic units on the drawings?
Then, based on your calculations, his request of 80 has no basis. Or you can change it to make it 80 in length.
It can be distinguished by “calculated volume” and “nominal volume”.
It is possible to specify both the total volume and the effective volume; the total volume is calculated based on the equipment specifications, and what is indicated must match the actual calculation.
Does that mean that since the total volume I calculated is 74 cubic units, it’s not possible to indicate 80 cubic units on the drawing?
The model number can be written as×××80, but the volume in the technical specifications table should be the actually calculated volume.
Where large capacity specifications are in effect, the volume must be calculated based on the actual design dimensions; rounding off may be done appropriately, but it’s not possible to increase the value arbitrarily as you do here
