Thanks for ur reply.ya i understand now but having one more clarification that in case of trunion calculation checkning the basic pd/2t formula is decribed in kellogs method for finding circumferntial presure in header. In that case can i replace the formula with High pressure stress formula ...
Hi,
Pipe thickness is generally calculated based on hoop stress formula whic is pd/2t. In ASME B31.3, the formula is modified as PD/(2SEW + PY) and it is used for calculation purpouse. However thickness obtained in the later is less than than the former one and still it is accepted because of...
hai Benstewart..
I agree with the concept that you had explained. Still I have doubt on combining the stresses to obtain the maximum/actual stress. My question is that why bending stresses are always combined with the longitudinal/axial stresses why can't it is combined with circumferential...
hai all,
In the code stress calculation as per ASME B31.3 for sustained case the equivalent stress Se is combination of axial stress, bending stress and torsional stress alone. i.e., Se= √(│Sa│+ Sb)2 + (2St)2 ). Why Circumferential stress is not considered for finding the overall stress?
If...
