My shop is about to make some small Titanium pressure vessels with two welded nozzles and I'm wondering if we need to stress relieve the weldment.
The material is Comercially Pure Grade 2 Titanium.
The vessels are 2.875" od x .203" wall thickness.
The nozzles are 1.05" od x .113" wall thickness.
Maximum Allowable Working Pressure is 1480 psi.
Hydrotest pressure is 2300 psi.
Nozzles are to be inserted halfway into the vessel wall and double fillet welded w/ .125" welds, GTAW manual.
Does this application require stress relieving?
Would Eddy Current or Penetrant Testing be recommended?
Thanks in advance for your consideration.

They're very kind people and will be glad to assist you.
Now let me ask you a curious question: those are very small vessels subjected to very high pressure. What will they be used for? If it's not a military secret I'll be happy to know it.

Thankyou Mr. Crisi for your always helpful information.
These vessels will work in tandem as part of a small, rather complicated Light Weight Water Purifier.
Thanks again,
Tim
