In process piping support allow stress is higher than power - 08/28/18 01:19 AM
In process piping support allowable stress is higher than in power piping or MSS-SP-58(2009).
As per B31.3 clause 321.1.3, pipe support allowable stress in tension is as per B31.3 para 302.3.1 (Su/3 at room temp and Sy/1.5, whichever minimum)
In B31.1 & MSS-SP-58 2009), at room temp allowable stress in tension is Su/3.5 at room temp and Sy/1.5, whichever minimum .
Is my above understanding right that in B31.3 we can go for higher allowable than in power piping ?
