ASME B31.3 using A707 L3 CL3 Pipe Shell (allowable stress?)
ASME B31.3 using A707 L3 CL3 Pipe Shell (allowable stress?)
(OP)
Can you please inform me as to how I go about determining allowable stress values @ temperature for ASTM material A707 L3CL3?
I will be using this material, as specified by my customer, to make a section of, what is essentially straight pipe for a B31.3 application.
I understand section 323.1.2 Unlisted Materials of B31.3 and Appendix 5 of section 2.
I just do not understand where to get yield or tensile values at temperature for ASTM material.
Any help is much appreciated.

So for the B31.3 applicable tensile values you may have to convert the II-D tensile values. That would mean multiplying it be 4, dividing it by 3.5, if Im not mistaken.
Yield values are listed in table Y if Im not mistaken.

This makes sense to me.
But where o where, in the world do i find stress curves for ASME unlisted materials (A707 GR3CL3 particularly)?
Im really in need of some guidance here.
Im reading myself in circles.
Im in
SecII-D, APPENDIX 10
B31.3 302.3.2 Bases for Design Stresses
and so on
any help much appreciated!
