Given a control block of simplicity with only two bores. These two bores could be parallel or just could be very close to each other at a specific point in the control block.
The material of the control block is cast iron GJS 400:
- Tensile strength $400 \, N/mm^2$
- 0,2% proof stress $250 \, N/mm^2$
- Fatigue strength $225 \, N/mm^2$
- Elongation at break $15 \, \%$
The diameters of the two bores could be the same but also could be different. The pressure in bore 1 is 350 bar and in bore 2 280 bar.
My question is how to calculate the minimal needed wall thickness between the two bores.
Sadly I haven’t found anything proper – only a calculation regulation of pipes…
Or is there a possibility to transfer these pipe results to my bores within the control block?
Any suggestions appreciated and many thanks in advance!
