Title: Trying some Chinese Titanium tube
Post by: csdilligaf on July 29, 2016, 07:33:01 PM

God, I hate made in China stuff but I could not pass up on this 50mm tube.  I got a few of them and they do not look to bad.  The wall is more like .125".  Has anyone tried it for a pressure vessel?  I just wish I could get it from a known good source in the USA but had no luck.  I can test it here up to 12K psi so we'll see if it holds. Will let you know.

I built a rig to test here at home.  I know the numbers work but when you add in the China factor I get nervous.

Be safe!
here, we used those 0.125 wall ti-tube playing just around 2700-3000psi.

Hope to see the best result from you
