What is the correct way to display the material specifications? 1

[Cesar Almada]

Hello everyone i have a question about what is the correct form to show o mention the material specification?

I have these two materials, all in GRADE B and Sch 80.

Welding Straight Tee 12 '' x 12 "x 12" Thick 0.688 ’’ ASME B16.9 Carbon Steel ASTM-A105 Grade B
Welding reduction of 16 '' Ø Thickness 0.844 '' x 12 '' Ø Thickness 0.688 '' ASME B16.9 carbon steel ASTM-A105 Grade B
Welding reduction of 12 '' Ø Thickness 0.688 '' x 10 '' Ø Thickness 0.594 '' ASME B16.9 carbon steel ASTM-A105 Grade B
Welding reduction of 12 '' Ø Thickness 0.688 '' x 8 '' Ø Thickness 0.500 '' ASME B16.9 carbon steel ASTM-A105 Grade B
12 '' Ø 90 ° welding elbow 0.688 ’’ ASME B16.9 carbon steel ASTM-A105 Grade B
12 '' Ø 45 ° welding elbow 0.688 ’’ ASME B16.9 carbon steel ASTM-A105 Grade B
12 "Ø welding cap 0.688’ ’ASME B16.9 carbon steel ASTM-A105 Grade B
1-1 / 2 "Ø ASTM A106 Grade B Schedule XS ASME B36.10 Seamless Carbon Steel Pipe

My question is, if i need to put A239 or is correct A105 because i read here something like A239 is for butt weld and A105 is for threaded? to end i have weld neck flanges A105.

Thank you !! cheers

In pipeline work many non-standard pipe wall thicknesses are used, hence it is not possible to use schd sizes all the time and we list both when applicable.
