The CAESAR II material database does not have all of the materials from the Code books, only the most frequently used.

If you use A358 304L CL3 frequently in Version 12, you can use the "Material Database Editor" and add this material to the database.

Hello MikeOP,

Product development ticket is filed on your behalf to include this material in future release of CAESAR II.

Class 3 means Pipe is single welded by filler metal in all passes and completely radiographed, otherwise is still 304L there. Class 1 pipe is double welded and radiographed.
Where is the reference to Class 3 in B31.3? I can find references to Class 1 in IID, in Shell MESC, etc.

CAESAR II v12 supports only 2018 edition. Thus, the material and properties match as expected for 2018 edition.

The requested material should be "(196) A358 304L"; the book calls it "A358 304L CL 1&3". Since the book does not differentiate between CL1 and CL3, there was no reason to add the "class" designation in CII.

For B31.3 for A358 304L you need to use material 196. In addition to use the provisions of table A-1B, i.e quality factor Ej. For class 1,3,4 Ej=1.
Material 199 is special entry for A358 304L for use with B31.1.

B31.3 have a different approach than B31.1 for example.
If you access the help for Eff in Caesar input spreadsheet for allowable stresses you will see the following explanation:

B31.3, B31.4, B31.4 Chapter XI, B31.8, B31.8 Chapter VIII, B31.9, NAVY 505, Z662 (J), BS 806 (e), CODETI (z), FDBR (vl), GPTC/Z380

Allowable stress or yield stress tables do not include longitudinal weld joint efficiencies. Eff is ignored for the flexibility calculations. SH is multiplied by Eff when calculating the minimum wall thickness.

Due to this particularity, it it not required to have different material entries for different classes, the allowable will be the same. The only thing is that you will have to consider Eff only for minimum wall calculation.

of course if Coade want to be more specific in the material database, even if the allowable is the same, they can do this easy, I think.
It is always preferable that the database is the Coade one even it can be modified / edited by everyone. Editing the database may be quite questionable sometimes, if some values are altered and system pass when it shouldn't (without intention of course ).

Mike,

In B31.3 IX where the main concern is pressure I can see there is no difference between properties of A312 TP304L and A358 304L Cl1 and 3, providing that applicable notes are considered for procurement. In B31.1, their experience dealing with high temperatures of welded pipes ended with a different approach. It's hard to say there is a science behind, it's just the "Code".
