Need Calculation Help

(OP)
Could some one explain the following, and is this from the code

Calculations as well as in working conditions as in test conditions
tmin = PLM / (2SE-0,2P)  with M = 0,25 (3+ (R/r) 1/2)

 

RE: Need Calculation Help

Can you tell us in which code (page and paragraph number if you have them)?

RE: Need Calculation Help

Yes, it is from Appendix 1-4 for torispherical heads, excpet in the formula for M, "R" should be revised to "L", same "L" as used to calculate tmin. L is inside crown radius, r is inside knuckle radius. M is a factor depending on L/r.
 

RE: Need Calculation Help

ASME Section VIII Division 1, ASME Section VIII Division 2, ASME Section VIII Division 3, British Standards, ISO Standards, etc. ?
