Hello!
We can use A335-P92 material in AutoPIPE, but I don't know where the material properties come from.
I can find only thermal expansion coefficient and allowable stress from ASME B31.1 and ASME Sec II, Part D respectively. But they are a little bit different from the values in AutoPIPE.
Even, I can't find elastic modulus of A335-P92 in code.
What is the basis of A335-P92 material properties in AutoPIPE?

Hello Hyukchan Kwon,
See WIKI here , example #3, for details on how to find out this information from AutoPIPE help. It is a very simple process. To answer your question directly for material library = B311-14:
From the Code Dependent Pipe Materials, find the following:
Use UC1, and open the same code year Standard Pipe Material library to find the following:

Hi Mike,
But there seems to be a problem !
The reference for thermal expansion as well as "Elastic Modulus" from T92/P92 Book, Vallourec & Mannesmann Tubes (2000) seems to be superseded by article PWR2005-50110 (ASME Power) 2005 article.
And there is a huge difference in particularly the Hot Modulus of Elasticity huge should be much lower than the ones of Vallourec book.
With best regards,
