Chemical Composition
99.2% pure titanium with regulated interstitial elements makes up grade 2 titanium. For the best weldability, the oxygen level stays below 0.25%.
Grade 7 palladium-stabilized provides improved resistance to reducing acids. Complete EN 10204 3.1 material certificates with heat number traceability are included with every batch.
Manufacturing Process
Cold rolling technology maintains thickness tolerance within ±0.05mm. CNC machining ensures precise bolt hole positioning and flatness standards.
Welding procedures follow ASME specifications without filler metals. This preserves base metal corrosion resistance throughout the weld zone.
Final heat treatment relieves residual stress. Surface pickling removes contamination while maintaining dimensional accuracy.
Quality Inspection
Every Flat welding flange undergoes ultrasonic testing to detect internal defects. Eddy current inspection verifies surface integrity across 100% of production.
Dimensional verification uses CMM equipment for accuracy confirmation. Pressure testing at 1.5x operating pressure ensures leak-proof performance.
Third-party certification available through SGS, BV, and TÜV upon request.
Applications
Chemical processing plants utilize our flanges for acid transfer systems. Seawater desalination facilities require corrosion-resistant connections.
Offshore oil platforms benefit from lightweight yet strong titanium construction. Pharmaceutical manufacturing demands FDA-compliant material grades.
