High Temperature Flange
High Temperature Flange
(OP)
Hi,
I am working on a filtration vessel that will have an operating temperature of 850˚C. The vessel will be constructed of Alloy 800HT. At this temperature the material will have a limited life service because it is in the creep range.
The flange temperature in ASME B16.5 (2009) for this material goes up to 816˚C. Two questions on this,
Is this because the material will be within the creep range above this temperature?
Is it possible to use this material above 816˚C in a flange application?
Thank you,
timlynx

RE: High Temperature Flange
If not, then you'll have to custom-design your flange based on your vessel's code of construction, like say ASME VIII-1 Appendix 2.

By the looks of it, i will have to prove the clasification via calculations and have a limited life service.

Section II-D tells me that SB-564 may be used up to 899 deg C max.
See applicable notes G4, T16, G4, G5, T15
