In B 31.3 sustained/ occasional stress - design pressure ? - 05/19/08 06:21 AM
In B 31.3 sustained/ occasional stress - for longitudinal pressure stress slp = pDi^2/(Do^2-Di^2) or pDo/4tn, we consider p as design pressure(g) as it is that pressure that will provide greatest required pipe thickness & so highest slp possible as per B 31.3 design pressure definition.
But, I have noted many using various operating pressures listed in line designation table in slp computation; aren't they wrong in approach ?
