Pharos, i have some experience with chinese/taiwanese titanium frames, we sell about 1500 a year. If the welds look good, and it's not checmical gas grade pipe you should be ok. I've been to a lot of vendors and quality varies hugely. Those who do full argon purge and double pass welds, then apply the correct heat treatment are few and far between.
