6000 psi Socket Weld Flanges
6000 psi Socket Weld Flanges
(OP)
So I am looking for Socket weld flanges and fitting that can handle 6000psi, are stainless steel and come in a diameter of about 3in for our new hydraulic plumbing setup. Every time I get close to finding what I think I want it end's up being wrong working pressure as most flanges stop at 2500psi. We normally only deal in 37deg flared tubing #20 and smaller so this is a whole new world to me and I cant find anyone who sells what I want in a catalog or on there web site. Would really like to find somewhere that sells these fittings so I can get dimensions, draw up our layout and order said fittings. Please forgive my ignorance as this is 100% new to me. Thanks

They do fittings, but if you're going for flanges then you need either autoclave or wellhead type fittings ( API 6A)
something like this http://autoclave.com/aefc_pdfs/vftcc_english.pdf

As 1gibson stated, 2500# stainless steel flanges between -20o F to 100o F are rated for up to 6000 psig according to ASME B16.5.
Do you have a copy on hand?

- weld necks, instead of socket welds, as mentioned.
- group 2.8 flanges. These are duplex stainless steels (F44, F51, F53, F55). They go up to 6250 psi at ambient, which is a bit more on the safer side ("so want to error on side of caution when I can") compared to the 6000 psi rating.
- use a kammprofile gasket, graphite filler and 316 ring.
- use PTFE (Xylan) coated A193 B7 bolts or similar

If you can go down to 2" or 2 1/2", many of the normal hydraulic fitting suppliers should be able to cope with this.
