Our Titanium Blind Flanges (BL) are engineered for critical applications where standard stainless steel fails. Designed to provide a reliable, leak-proof seal at the ends of piping systems, pressure vessels, or valves, these flanges leverage the unique properties of titanium to ensure long-term integrity in the most aggressive environments.
Whether you are handling high-temperature chemicals or corrosive seawater, our titanium solutions offer the perfect balance of lightweight performance and high mechanical strength.

Key Benefits
Superior Corrosion Resistance
Titanium naturally forms a stable, protective oxide film. Our flanges are immune to pitting and crevice corrosion in chlorides, sulfides, and nitric acid, making them ideal for desalination and chemical processing.
High Strength-to-Weight Ratio
With nearly 50% less weight than steel but equivalent strength, our titanium flanges reduce the overall structural load on your piping system while maintaining high-pressure integrity
Precision Forging & Machining
Unlike cheap plate-cut alternatives, our blind flanges are 100% forged. This ensures a refined grain structure, eliminating internal defects and guaranteeing performance under cyclical thermal stress.
Temperature Stability
Maintains mechanical properties from cryogenic temperatures up to 400℃ (depending on grade), ensuring safety in volatile industrial cycles.
Typical Applications
Offshore & Marine: Desalination plants, subsea equipment, and ship building.
Chemical Processing: Production of chlorine, chlorates, and organic acids.
Oil & Gas: High-pressure sour gas environments and refinery cooling systems.
Power Generation: Heat exchangers and condenser systems.
Quality Assurance & Testing
We don't just ship products; we ship peace of mind. Every flange undergoes:
PMI Testing: Chemical composition verification (Grade 2 vs Grade 5).
Ultrasonic Testing (UT): To detect any internal flaws or porosity.
Dimensional Inspection: Guaranteeing 100% compliance with ASME/DIN tolerances.
Certification: Full MTR (Mill Test Report) provided according to EN 10204 3.1.
