F65 VS ASTM A105N FLANGE TEST PRESSURES
F65 VS ASTM A105N FLANGE TEST PRESSURES
(OP)
Hello,
Can anybody advise me what hydrotest test pressures the below flanges can safely take:
1) 3"SCHXXS WN 10000PSI RTJ API6A 6BX - ASTM A105N
2) 3"SCHXXS WN 10000PSI RTJ API6A 6BX - ASTM A694 F65
3) 8" x 25.4mm WN 10000PSI RTJ API 6A 6BX - ASTM A105N
4) 8" x 25.4mm WN 10000PSI RTJ API 6A 6BX - ASTM A694 F65
5) 10" 18.3mm WN CL2500 RTJ API 6A 6BX - ASTM A105N
6) 10" 18.3mm WN CL2500 RTJ API 6A 6BX - ASTM A694 F65
The reason i ask is that we have some spools that require hydrotesting, but some spools have open ends that will be tied in offshore..therefore i need to know if the proposed "temporary flanges" will be capable of seeing a hydrotest pressure of 444Barg for the CLASS 2500 flange & a pressure of 786Barg for the 10000PSI flanges.
I look forward to your responses.
Kind Regards.

RE: F65 VS ASTM A105N FLANGE TEST PRESSURES
BTW what is a #2500 6A6BX flange. This is mixing two flange codes surely?
Are you making this up? Table 5 of API 6A only lists 60K and 75K material for a 10000 flange.
A105 doesn't normally come in yield strength that high so who is suggesting you use a amterial which isn't listed in API 6A??
BTW this isn't really a "Boiler and pressure vessel" forum question. You're better off in pipelines piping and fluid mechanics...
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
