3. Grades of Titanium Weld Neck Flanges

Titanium weld neck flanges are commonly used in piping systems due to their strength, light weight, and excellent corrosion resistance. These flanges are available in various grades, each tailored for specific applications and environments. 

1. Grade 1 Titanium: Known for its high ductility, grade 1 titanium is the softest and most formable of all the commercially pure titanium grades. It's mostly used in applications that require superior corrosion resistance in environments such as the chemical processing industry.

2. Grade 2 Titanium: This is the most widely used titanium grade. It offers a good balance between strength and ductility, with excellent corrosion resistance. It is used in a broad range of applications, including flanges for piping systems.

3. Grade 5 Titanium (Ti 6Al-4V): This is an alloyed grade and the most commonly used of all titanium alloys. It significantly increases the strength of the flanges compared to pure titanium grades. Grade 5 titanium is used in high-strength applications where both heat and corrosion resistance are required.

4. Grade 7 Titanium: Featuring excellent weldability and fabricability, this grade includes palladium for enhanced corrosion resistance, particularly against reducing acids and localized attack in hot halides.

5. Grade 12 Titanium: This grade offers enhanced heat resistance and strength compared to other commercially pure grades. It also maintains good weldability and corrosion resistance.

6. Grade 23 Titanium (Ti 6Al-4V ELI): This grade is similar to Grade 5 but has extra low interstitials (ELI), making it preferable for higher fracture toughness and improved ductility. It's often used in medical applications and also suitable for flanges in critical, high-end applications.

4. Why We Choose Titanium Weld Neck Flanges in the Industry?

Titanium weld neck flanges offer a range of advantages that make them highly sought after in various industrial applications where performance and durability are crucial.

High Corrosion Resistance

• Exceptional Durability: Titanium is renowned for its superior resistance to corrosion compared to most other metals. This makes it ideal for harsh environments, such as those found in marine, chemical processing, and offshore industries.
• Resistance to Pitting and Crevice Corrosion: Especially critical in applications involving seawater or corrosive chemicals, where other materials might fail.

Strength and Lightness

• High Strength-to-Weight Ratio: Titanium flanges are lighter than those made from stainless steel or carbon steel, which is a significant advantage in aerospace and automotive industries where reducing weight is crucial.
• Maintains Integrity Under Stress: The inherent strength of titanium allows these flanges to withstand high stress and pressure without compromising their structural integrity.

High Temperature Performance

• Stability in Extreme Temperatures: Unlike many other metals, titanium maintains its strength and does not become brittle at low temperatures or lose strength at high temperatures, making it suitable for a wide range of operating conditions.

Longevity and Cost-Effectiveness

• Long Service Life: Due to their robustness and corrosion resistance, titanium flanges can last significantly longer than other flanges, reducing the need for frequent replacements.
• Lower Lifecycle Costs: Although the initial cost is higher, the longevity and reduced maintenance requirements can make titanium flanges more cost-effective over time.

Weldability

• Reliable Welding Performance: Titanium weld neck flanges are designed for direct welding to the piping system, providing a strong, seamless connection that enhances the overall strength and leak resistance of the system.

Enhanced Safety

• Reduced Risk of Leaks: The weld neck design creates a strong bond with the pipe, which is crucial in high-pressure applications to prevent leaks and ensure safety.

Environmental Resistance

• Withstand Harsh Environments: Besides corrosion, titanium is also resistant to damage from a variety of environmental factors including UV radiation, biological fouling, and chemical exposure.

Versatility

• Wide Range of Applications: These flanges are used in industries as diverse as chemical processing, aerospace, military, marine, petrochemical, and power generation due to their superior properties.

5. Applications of ANSI B16.5 Titanium Weld Neck Flange

Titanium weld neck flanges are used in various industries including petrochemical, oil and gas, power generation, bulk liquid transportation, chemicals, pharmaceuticals, pulp and paper manufacturing, textiles and others. Titanium weld neck flanges are packed to ensure that there is no damage during shipment. In case of export, standard export packaging is done in plywood box. Markings can be made as you require.

6. Packages of Titanium Weld Neck Flange

1. Rust Prevention

• VCI (Volatile Corrosion Inhibitor) Wrapping: Titanium flanges are wrapped in VCI paper to prevent any surface corrosion during transit. This material releases a chemical vapor that forms a protective layer on the metal surfaces.
• Grease or Oil Coating: A light layer of grease or oil may be applied to protect the flange surfaces, especially when being shipped over long distances or stored for extended periods.

2. Physical Protection

• Bubble Wrap or Foam: Each flange is typically wrapped in bubble wrap or surrounded by foam to cushion against impact during transportation.
• Cardboard Separators: When multiple flanges are packed in one box, cardboard separators are used to prevent them from touching and potentially scratching or damaging each other.

3. Robust Outer Packaging

• Wooden Crates or Plywood Boxes: Titanium flanges are often shipped in wooden crates or plywood boxes, which provide sturdy protection from mechanical damage and are stackable, facilitating easier and safer handling.
• Palletization: For large orders, flanges may be palletized. Each pallet is usually shrink-wrapped to secure the boxes or crates during handling and shipping.

4. Waterproofing

• Plastic Sheeting: Outer crates or boxes are often covered with thick plastic sheeting to protect against moisture, especially in humid or wet environments.

5. Labeling and Documentation

• Clear Labeling: Each package is clearly labeled with handling instructions, part numbers, and destination details to ensure proper handling and to facilitate tracking.
• Quality Assurance Documentation: Certificates of quality, material test reports, and compliance certificates are often included in the packaging or provided separately to ensure traceability and compliance with industry standards.
