[QUOTE=company man 1;35679]The highest burst rating I found for 22" casing was 2500 PSI.[/QUOTE]
For grade X-56 very likely.
They used X-80 224lb/ft according to MMS. This I think is newer, higher strength steel?.
Anyway, I still haven’t found any accurate data yet though. I’ll keep digging.
KASOL… any ideas?
