Yield Strength Vs Wall Thickness/Cross-Section
Yield Strength Vs Wall Thickness/Cross-Section
(OP)
Hi All,
Does anyone knows where do I find the relevant documents based on the material yield strength and the maximum diameter it can go?
For example, yield strength of the following AISI 4130, 4140, 8630, F22, 4330 and 4340 may varies and therefore, restricting the wall thiokness.
May I ask how to Materials Engineer derive this? Any information I can look into?
Thanks,
Jeffrey

the rest is how each company 'confident' to mention expected wall thickness of those steel.

Thanks. You made a point here. However, I think in oil and gas companies, they have this "guidelines" to determine the specified minimum yield strength (SMYS) and what is the maximum wall thickness it can go.
Hi yudhichen,
Thank you! I will read the ASTM A255 mentioned.

Hi weldstan,
I just checked the API 5LX-60, it seem that it is not in use anymore.
Thanks,

The thicker you buy your rolled plates, the lower the values. see the attached screenshot, this is for "regular" steel (low alloyed, low strength).

X60 is still in API 5L, 45th Edition, Erata 1, as either Grade L415 or X60. See Table 6.

Thanks weldstan. I will take a look.
