Titanium Vessel Heads and Forged Nozzles for Corrosive Process Equipment
Titanium vessel heads and forged nozzles are pressure-boundary components whose material, geometry, fabrication and inspection must be considered together. Corrosion resistance cannot compensate for incomplete pressure design or poor weld details.
Component Roles
| Component | Role | Critical controls |
|---|---|---|
| Vessel head | Closes the shell pressure boundary | Profile, minimum thickness, straight flange and weld fit-up |
| Forged nozzle | Creates a reinforced branch or equipment connection | Bore, wall, transition, weld end, machining and NDT |
Corrosive-Service Review
Define media, concentration, temperature, pressure, chlorides, crevices, deposits, aeration, galvanic contacts and cleaning. Grade 2 is common in many oxidizing environments; palladium-alloyed Grade 7 or Grade 12 may be considered for selected service only after materials review.
Fabrication Interface
Head-to-shell and nozzle-to-vessel welds require compatible filler and procedures, contamination control, fit-up, purge or shielding, heat input and examination. The purchaser should align material certificates, drawing revisions and weld maps.
