Titanium Weld Neck Flange ASME B16.5 Class 150 Ti Gr2 Gr5 Gr7 Raised Face WNRF for Pipeline Applications

2. Grades of ASME B16.5 Titanium Weld Neck Flange Class 150 

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.  

3. 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.

4.  

5. 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.

6.  

7. 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.

8.  

9. 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.

10.  

11. 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. Advantages of ASME B16.5 Titanium Weld Neck Flanges:

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.

Corrosion Resistance: Titanium weld neck flanges are highly resistant to corrosion, even in aggressive environments such as seawater, acids, and chlorides. This makes them ideal for industries like chemical processing, marine, and offshore oil and gas where corrosion resistance is critical.

Strength-to-Weight Ratio: Titanium has a high strength-to-weight ratio, making titanium weld neck flanges strong and durable while remaining lightweight. This is advantageous in applications where weight reduction is desirable without compromising strength and performance.

High Temperature Resistance: Titanium weld neck flanges can withstand high temperatures without losing their mechanical properties. They maintain their strength and corrosion resistance at elevated temperatures, making them suitable for applications involving heat and thermal cycling.

Biocompatibility: Titanium is biocompatible and non-toxic, which makes titanium weld neck flanges suitable for use in medical equipment, pharmaceutical manufacturing, and food processing industries where product purity is essential.

Longevity and Durability: Titanium is known for its durability and long service life. Titanium weld neck flanges exhibit excellent resistance to fatigue, erosion, and wear, contributing to reduced maintenance and replacement costs over time.

Excellent Sealing Properties: The smooth surface finish of titanium weld neck flanges, achieved through pickling or machining processes, allows for superior sealing with gaskets or other connecting components. This helps prevent leaks and ensures reliable performance in critical applications.

Compatibility with Other Metals: Titanium weld neck flanges can be easily welded or paired with other metals such as stainless steel or carbon steel, allowing for versatility in design and compatibility with existing systems.

5. Packages of Titanium Weld Neck Flange

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.

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.

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.

Waterproofing

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

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.

6. Certificates of ASME B16.5 Titanium Weld Neck Flange:

EN 10204/3.1B Certificate:

This is a standard certificate that confirms compliance with the material specification and provides chemical composition and mechanical properties of the titanium alloy used in manufacturing the flanges. It is issued by the manufacturer and verifies that the material meets the required standards.

Raw Materials Certificate:

This certificate provides details about the raw materials used in the production of the titanium flanges. It includes information such as the origin of the raw materials, their composition, and any applicable material testing results. This ensures traceability and quality control from the initial material procurement stage.

100% Ultrasonic Flaw Detection:

Ultrasonic testing (UT) is a non-destructive testing method used to detect internal and surface defects in the titanium flanges. A 100% UT coverage means that all flanges undergo thorough testing to ensure there are no defects that could compromise their structural integrity or performance.

Hydrostatic Test:

This test involves pressurizing the titanium flange with water or another liquid to a predetermined pressure level. It assesses the flange's ability to withstand pressure without leakage or deformation, ensuring it meets the specified pressure ratings and safety requirements.

Third Party Inspection Report:

This report is conducted by an independent third-party inspection agency or authority. It provides an unbiased assessment of the titanium flanges' quality, confirming compliance with applicable standards, specifications, and customer requirements. It adds credibility to the manufacturer's quality assurance processes.
