Hallo everyone,
Wall thickness requirements for valve bodies are specified in para. 6.1. The minimum wall thickness values, tm, shown/calculated in:
1. Table 3
2. Wall thickness equation of Mandatory Appendix VI
3. Wall thickness equation (B-1) of Mandatory Appendix B
ASME B16.34 indicates in Mandatory Appendix B (paragraph B-1.3 Wall Thickness):
Equation (B-1) is included only as an item of general interest. Equation (B-1) is not to be used for design calculations and is not to be used as a substitute for either Table 3A or Table 3B values or Mandatory Appendix VI equations.
My questions:
1. Is a wall thickness calculation a design calculation?
2. Is it possible to use Equation (B-1) in mandatory appendix B to calculate the wall thickness?
3. What is the different between the equation of mandatory appendix VI and the equation (B-1) in mandatory appendix B?
Thank you very much for your time.
