SA-234 WP11, Classes 1, 2 & 3

SA-234 WP11, Classes 1, 2 & 3

SA-234 WP11, Classes 1, 2 & 3

(OP)
Section II-D lists only class one of the subject material in the allowables table.  Vendors give me the impression that classes 2 & 3 are difficult if not impossible to find.  I was wondering if anyone could shed any light?  Are classes 2 & 3 dead?  Or does Section II-D only list Class 1 because it has the lowest allowables of the bunch, and thus maintains the code's conservative nature?

RE: SA-234 WP11, Classes 1, 2 & 3

I did not look into ASME Sec II D but your guess may be correct.  ASTM lists the compositions for Class 1, Class 2 and Class 3.  Classes 2/3 permit a bit more carbon, phosphorus and sulfur.  Tensile strength is higher for Class 2 and Class 3 than for Class 1.  ASTM A 234 lists mandatory fitting markings.

RE: SA-234 WP11, Classes 1, 2 & 3

SA 234 WP11 Class 2 and 3 are not in Section II, Part D. The only reason I can think of is that these Classes of materials are not that common and unless there is a need or desire for use, one would need to formulate a Code Case for use.
