(PLEASE NOTE: This is a crosspost with B&PV forum)

I am wondering if there is any verbage in the B&PV code regarding the use of a material not specifically listed in Section II Part D and if so, where is this information located? Bottom line, I would like to use a seamless tubing supplied by my vendor as TP316L per A269 but the code does not permit the use of A269. The material spec required for TP316L seamless tubing per the 1998 code (as I see it) is an SA213. The question is this - can I find a way to legally substitute the A269 for the SA213?

Thanks!
