Metengr,
Thanks for all of your great answers and info regarding my pressure vessel questions over the past few months! Are you available as a consultant offline? We have been working with an ASME shop for projects like these but lately they have been less inclined to respond to inquiries...
I realize there isn't any data for CL-150 flanges above 1000F. At very low pressures (20psi) - is there any reason I cannot use an incoloy 800H/HT flange (N08810) around 1500F?
Flange and attached pipe will all be solution annealed at 2100F.
Thanks!
All,
I finally rec'd Section II Part D and I have an issue. P. 246 lists the Incoloy Alloys N08811 and N08810 and MAXIMUM service temp is 1650 - metengr where are you getting the values up to 1800F?? I don't see anything in either of the addenda's.
Any help is greatly appreciated, thanks!
Sorry, when I say "grow" - I mean from a design standpoint. If I need a 10" pipe size bored out to give me the intended ID I need (for what goes inside the pipe later) that's no problem. Subsoquently if I need 10" flanges that is fine too. Primary design needs to have a 2.5" ID and be able to...
My regular pressure vessel shop cannot recommend designs that would be suitable for 525F/5,125psi for a 2.5" and 1.25" pipe. I need to maintain the ID for these pipes with a standard sched. 40 thickness (ie, 2.469"ID and 1.28"ID respectively) - but I don't care if the pipe needs to grow...
metengr - thank you for all of your help with my questions - it is most appreciated. These requests for pressure vessels are becoming more and more frequent so I'm trying my best to wrap my head around it.
In your opinion, can I perform decent "reality checks" of designs BEFORE going to my ASME...
Hello,
I do not have access to B16.5 but I would like a reality check on a slip on flange that would be capable of 550F and 5,250psi. In my table of service ratings for SS not even CL-2500 flanges can get that hot. Any thoughts?
Thank you.
Ok, thanks. I just found the table of contents for the entire B&PVC code book - I had no idea it was so inclusive. In that case, would it be possible to get the range of allowable stress values according to Section II Part D starting at 1000F and going up in 100 degree increments? Any help is...
OK - thanks again for all of your responses. I rec'd my BPVC but I only ordered Section VIII/Division 1 - I don't see any stress values in it. Do I really need to order Section II part D???? What a scam!!
Thank you metengr and TVP - as you can see I'm right on the edge and I'm getting conflicting reports.
If I specify the UNS N08811 alloy for Incoloy I can get to a higher temperature, right?
Thanks again.
Matt
Hello,
My customer is looking for a pressure vessel that can handle 950C and 50psi in a 50% 02 environment. I've spec'd Incoloy 800HT but I can't find any S values at these conditions. I am awaiting my BPVC-VIII code book in the mail, hopefully that will have it. But in the meantime I just...
