Who can suggest suibable titanium pipe and flange materials

Who can suggest suibable titanium pipe and flange materials

(OP)
Currently I have to make a small spool of titanium to connect a titanium pump to plastic lined pipe system (for brine fluid). I am wondering what pipe and flange material standards I should use in ASME/ASTM system?

thanks

RE: Who can suggest suibable titanium pipe and flange materials

Consider ASTM B337 for Pipe and ASTM B381 for Flanges. Each standard has more than one grade. You'll need to find out what is available and what meets your design requirements.

RE: Who can suggest suibable titanium pipe and flange materials

Flanges of solid titanium are unusual due to cost.  Most people use lap joint stub ends with painted carbon- or stainless-steel backing flanges.  

As to grade selection, it depends entirely on the service.  Commercially pure titanium (gr2) is the most commonly used.  Grades 1-4 are all commercially pure titanium with varying oxygen/nitrogen contents.  "Brine fluid" isn't descriptive enough to help much in selecting a grade.  Have a look at www.timet.com for some useful information on titanium.

Any particular reason you just don't have a "plastic-lined" spool made up to mate with your pump?  Probably cheaper, especially if your titanium spool will require welding...

Thank you for the answers, they are so helpful. In fact the titanium spool is for connecting the titanium victaulic pump nozzle to the plastic lined pipe (flanged). I am intended to used a nipple(victaulic groove at one end) welded to a titanium flange.
