1946 ASME Sect 8
1946 ASME Sect 8
(OP)
In 1944 the material design factor changed from 5:1 to 4:1 does anyone know when it changed back to 5:1 before permanently being changed in 1951 to 4:1. I have a U1 from 1947 vessel that calculates out with a factor of 4:1 but the 1946 code has a 5:1 design factor. if anyone has any info let me know. PS. I have contacted ASME and the sec8 engineer let me know that ASME does not have any code cases prior to the early 1970's. one of the code cases in question is CC986 from 1942.

Another triva item: Has anyone else ever seen a "NPP" stamp. ASME issued a few of them in the late 60's early 70's.
