NPT size for 7500 psi??
NPT size for 7500 psi??
(OP)
I need a larger NPT hole than 1/2" for a 7500 psi. We have been testing at 4500 psi with a 2" NPT (fill with water). But now we are testing at 7500 psi. I know API says 1/2 NPT for 10,000 psi, but is there any other spec I can use for a larger NPT at 7500 psi???

There is a report available on Awhem website for gas testing of 2" LP thread which held up to 12.7 ksi. Awhem had proposed some changes to API 6A which would allow 1/2" - 4" LP connection to 10K WP. I think API had opted for acme thread instead but nevertheless the report is valid. Only thing is that the material need to be min. 60K yield.
