Applications
Titanium and Zirconium Stub End Applications
Often used in conjunction with standard lap joint flanges, zirconium and titanium pipe stub ends provide seamless connections, while limiting corrosion in piping systems. Made with premium materials, these fittings withstand oxidizing acids and other corrosive fluids, including seawater, mineral acids and alkalis. Common applications include:
- High-pressure pipelines in the oil and gas industry
- Pulp and paper processing equipment
- Marine engineering and shipbuilding
Materials
| Titanium | Zirconium |
| CP-TI (Grade 2) | 702 |
| TI-PD (Grade 7) |
