Dear friend
As per Clause 304.1.2 (a) of ASME B 31.3, the formula is acceptable if (with t<D/6 )
Questions :
1)"t" is Calculated Design Thickness (Excluded 12.5% / C.A ) or nominal?
2)If nominal Thickness (SELECTED THICKNESS) Has been selected so that t>D/6, What will be the B31.3 rule?
real Case :
Client PMS ==>PIPE 6" A106 THK 30.12 mm====> D/6=168/6=28 mm===>30.12>28
Max THK as per B36.10 for 6" is XXS(21.95)
