Flanges API 6BX to Standard pipe

Flanges API 6BX to Standard pipe

Flanges API 6BX to Standard pipe

(OP)
Hello,

We need to connect API 6BX flanges to ansi pipe. we have thinked  use transition pieces but we saw in your web page that api 6A no longer specify these transition pieces. It means that it is not a good  practice use these transitions pieces, in this case how can we connect api 6BX flanges with standard pipe?

Thanks in advance.

Regards

RE: Flanges API 6BX to Standard pipe

what size flange and what size pipe are you trying to weld together?

You need to fit the flange end to match the pipe size. Taper the bore from 2.06 to the pipe ID. I can draw the flange for example, if needed.

jbeckhou,

Thanks for the information. If you can draw an example, I would appreciate it.

But I have several doubts, if I fit weld necks that match standard pipe sizes. Can Flanges bear Api monogram?

And I can fit welding neck of the flange but there is a slice of pipe "A" in the drawing (inside diameter) that it could be a point of corrosion. I don't know if it is better go to a transition piece to avoid these problems

Thanks Jason,

The drawing is very helpful. Only one question more, the drawing is an API 6B 5000 psi flange. Can we do the same for a API 6BX 10000 psi flange?.

Thanks

yes, 2k thru 15k, any size flange.
