To my knowledge, there has been no such Table 121.5 in B31.3.

Does anybody know why B31.3 specifies (Table 121.5, General Note C) the bending stress does not to exceed 2300 psi (15.86 MPa)

I beleive the 2300 psi is the allowable stress at 400 degrees C divided by 4, A106 grade A. I could understand it being divided by 2 (PD/2t), but am at a loss to explain the division by 4.

Can anyone set me straight.

Kind Regards

Conor
