Why does Compress not allow the opt

Why does Compress not allow the option of using SA-182 F22 Class 1 Long Weld Neck Flanges as a material choice?

pvrerate, I don't have the most current references at hand, but it may be because Cl 1 is not listed in B16.5.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Thanks so much. You are correct. In the past we have only used this material for Appendix 2 flanges that had a design temperature of 1015F to get a slightly higher allowable.
