SA-234 WP11, Class 2 not in ASME II D

[patchlam]

Dear Engineers,

Good day to you. Recently, I found out that SA 234 WP11 Class 2 is not listed in ASME II D. My supplier could only supply me Class 2 instead of Class 1 due to stock issue. Can anyone advise how can I use Class 2 in this case? Or does anyone know what is the reason that SA 234 WP11 Class 2 is excluded from ASME II D?

Thank you and appreciate much.

Perhaps because no one ever wanted or asked the Code committee to address it for use in code applications.
