Grade 2 vs Grade 5 vs Grade 7 Titanium Flanges for Process Piping
Titanium flange grade must be coordinated with the connected pipe, pressure design, facing, gasket, bolting, welding procedure and service environment. Material chemistry alone does not establish a complete flanged joint.
Selection Matrix
| Option | Purchasing consideration |
|---|---|
| Grade 2 | Commercially pure titanium for many corrosion-resistant process and seawater applications after design review. |
| Grade 5 | Ti-6Al-4V for higher-strength applications where service and welding compatibility are established. |
| Grade 7 | Palladium-alloyed commercially pure titanium for selected aggressive chemistry and crevice conditions. |

Avoid These Purchasing Errors
- Do not use grade alone as the complete product specification.
- Do not copy dimensions from a different product form or standard without review.
- Do not assume a surface appearance proves manufacturing route or certification.
- Do not omit service, mating-component, fabrication or inspection requirements.

FAQ
Can a quotation be prepared from grade and quantity only?
Only a rough discussion may be possible. A reliable quotation requires product form, dimensions, standard or drawing, condition, tests and documentation.
Should every optional test be requested?
No. Select tests that address the governing specification, service risk and project quality plan. Unnecessary testing can increase cost and lead time without improving suitability.
