Hello every one,
As per B31.3 304.1.3, D/t > 100, I am following the procedure outlined in the BPVC-VIII-1, UG28,UG29,UG30 I am trying to determine the minimum wall thickness required under external pressure, and the required stiffening ring. "A" factor that I found falls to the left material/temperature line chart.
the design pressure in my case is 0.7 bar (internal pressure). does it mean that external pressure is just atmospherique pressure?
Anyone who has performed or familiar with such calculation, his/he help would be very appreciated.
NB: 1- I couldn't find appendix L ,that has examples illustrating the use of rthe precedure.
2- I made a seach in this forum, I didnot find answers to my questions.
Thanks in advance
Yani.
