- Product Description
Titanium Flanges – Precision-Engineered Corrosion-Resistant Piping Components
Baoji Jucheng Titanium Industry Co., Ltd., situated in China's Titanium Valley, offers precisely constructed titanium flanges manufactured in compliance with GB/T 9112, ASME B16.5, ASME B16.47, & EN 1092-1 requirements. We have been producing titanium for over 20 years since 2004, and we maintain over 3,000 tons of titanium on stock for timely delivery. Flanges in Grades Gr1, Gr2, Gr5 (Ti-6Al-4V), Gr7, Gr9, Gr12, and Gr23 are available. They vary in size from NPS 1/2" to 48" (DN15-DN1200) and in thickness from Sch5S to Sch160. To achieve tensile strength ≥345 MPa and yield strength ≥275 MPa in Grade 2, Modern forging, heat treatment, and CNC machining are used in the production of each flange to guarantee reliable performance in demanding media.

What Are Titanium Flanges?
Titanium flanges are crucial connecting components in piping systems. Bolted connections are used to join pipes, valves, pumps, and other equipment
In highly corrosive environments, these components address premature failure issues. When traditional stainless steel is exposed to chlorine or seawater, it corrodes in pits and cracks
Your flanges create a passive layer of self-healing titanium dioxide (TiO₂). In oxidizing acid settings, corrosion dangers that damage weaker metals are eliminated by this protective layer.

Key Advantages of Our Flanges
Increased Resistance to Corrosion
Seawater, acidic solutions, and chlorine gas are examples of harsh media that your flanges can withstand. In conditions when carbon steel fails in a matter of months, the passive oxide layer stops pitting corrosion.
Outstanding Ratio of Strength to Weight
Titanium has about double the strength-to-weight ratio of 316L stainless steel, with a density of 4.51 g/cm³. This lessens the structural pressure on aeronautical assemblies and offshore platforms.
Longer Service Life
Porosity faults are eliminated by our pressure-forged production technique. Under cyclic pressure loading, fatigue life is maximized by aligning grain flow with flange shapes.
Quick Delivery Assistance
We keep 3,000 tons of titanium on hand all year long. This guarantees stable supply capability and shorter delivery times for your urgent projects.

Applications Across Industries
Our flanges have vital roles in several industries:
Chemical processing: Managing chloride solutions and oxidizing acids without deterioration.
Marine engineering: Linking desalination facilities with seawater pipe networks on offshore platforms.
Aerospace: supplying fuel lines and exhaust systems with lightweight, high-integrity joints.
Biomedical: Making sure pharmaceutical processing equipment has sterile connections.
Power Generation: Reliability in cooling systems and heat exchangers.

Manufacturing Excellence
We use a rigorous quality-controlled method in our manufacture. Grain structure alignment is achieved by precision forging titanium ingots.
Mechanical qualities are optimized by heat treatment. According to ASME requirements, CNC machining produces precise dimensional tolerances.
Before being marked and packaged, every flange undergoes non-destructive testing. Every year, more than 500 sets of titanium equipment are produced at our 120,000-square-meter factory.
FAQ
Q: What grade should I choose for seawater applications?
A: Grade 2 offers excellent corrosion resistance for most seawater environments. Grade 7 provides enhanced protection in reducing acid conditions.
Q: Can you customize flange dimensions beyond standard sizes?
A: Yes, we manufacture custom sizes larger than DN1200 based on your engineering drawings and specifications.
Q: What pressure classes are available?
A: We produce flanges from Class 150 to Class 2500, with thickness ranging from Sch5S to XXS.
Q: How long is the typical delivery time?
A: Standard sizes ship within 2-3 weeks. Custom orders require 4-6 weeks depending on complexity.
Q: Do you provide material certificates?
A: Every shipment includes material test reports (MTR) certifying chemical composition and mechanical properties per ASTM B381.
