- Product Description
Titanium Flange B16.5 – High-Performance Flanges for Critical Industrial Applications
Baoji Jucheng Titanium sector Co., Ltd. has over 20 years of experience in the titanium sector and offers precisely constructed titanium flange B16.5 solutions for mission-critical circumstances.Our 120,000-square-meter facility produces flanges from an annual supply of 3,000 tons of titanium using state-of-the-art forging and CNC machining processes.With a density of 4.51 g/cm³, each flange—which is composed of Grades Gr1, Gr2, and Gr5 (Ti-6Al-4V)—is 56% lighter than steel.Grade 5 flanges have a tensile strength greater than 895 MPa.These products are utilized in sectors such as shipbuilding, offshore oil and gas platforms, airplanes, and chlor-alkali operations where material failure is unacceptable.They can withstand pressure levels ranging from Class 150 to Class 2500 and adhere to ASTM B381 requirements.

Key Technical Advantages
Better Material Characteristics
The grade 2 variants of our titanium flanges provide exceptional ductility and resilience to oxidizing conditions. Grade 5 (Ti-6Al-4V) has tensile strength above 895 MPa for high-pressure applications.
The flanges self-heal to produce a stable TiO2 protective oxide film in oxygen-rich environments. This ensures long-term sealing reliability despite temperature changes.
Outstanding Ratio of Strength to Weight
Compared to conventional steel flanges, your system weight decreases by 44%. Bolted joints experience less thermal stress during temperature changes because to the low coefficient of thermal expansion (8.6 µm/m·°C).
Method of Precision Manufacturing
To improve the grain structure, each flange is forged and then heated. ASTM B381-compliant dimensional correctness is guaranteed via CNC machining. Our skilled inspection team's strict quality control ensures that every piece satisfies your specifications.

Industrial Applications
Offshore Oil & Gas Production
Our titanium flange B16.5 units are deployed in subsea manifolds, FPSO cooling loops, and firewater systems. They solve microbially induced corrosion (MIC) and crevice corrosion issues that rapidly degrade steel in warm, oxygenated seawater.
ROV installation at depth is made easier by the high strength-to-weight ratio. Cathodic protection is not necessary for flange bodies with zero corrosion rates.
Chlor-Alkali Chemical Processing
These flanges join pipe spools that transport hot brine, hypochlorite solutions, and wet chlorine gas. One of the few metals that is completely impervious to wet chlorine conditions is titanium. You extend your service life by decades without experiencing any material deterioration.
Marine & Desalination Engineering
Titanium's zero-corrosion capability is advantageous for flanged connectors for deep-sea risers and desalination plant intake pipe. When the salinity is excessive, your maintenance intervals are much longer.
Our flanges manage brine evaporation units and PTA plant acetic acid streams at high temperatures without experiencing erosion-corrosion failures.

Frequently Asked Questions
Q: What pressure classes is your titanium flange capable of withstanding?
A: Class 150 to Class 2500 applications are served by our flanges. Depending on your unique technical needs and operational circumstances, custom pressure ratings are available.
Q: For marine applications, what distinguishes Grade 2 from Grade 5?
A: Grade 2 offers outstanding ductility and corrosion resistance for normal marine application. Grade 5 (Ti-6Al-4V) provides higher tensile strength for high-pressure systems where mechanical loads exceed Grade 2 capabilities.
Q: How long does it usually take to get tailored sizes?
A: Our 3,000-ton stockpile ships standard sizes in two to three weeks. Depending on the complexity of the forging and machining, custom dimensions usually take four to six weeks.
Q: Are you able to offer certifications and test results?
A: Yes. Mill test certificates, chemical composition analyses, mechanical property reports, and dimensional inspection records that meet ASTM B381 and your requirements are included with every batch.
