ASME B16.5 BLRF Flange Grade 2 Titanium Blind Flange Blank Flange Raised Face Class 150 For Oil And Gas Industry

3. ASME B16.5 Titanium Blind Flange Grades

Titanium Blind 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 Titanium Blind Flanges in the Industry

• Corrosion Resistance: Excellent resistance to corrosion in various aggressive environments.
• Strength-to-Weight Ratio: Provides strength and durability while remaining lightweight.
• High Temperature Resistance: Maintains mechanical properties at elevated temperatures.
• Biocompatibility: Non-toxic and biocompatible, suitable for medical and food processing applications.
• Longevity: Durable and long-lasting performance, reducing maintenance and replacement costs.

5. Applications of ANSI B16.5 Titanium Blind Flange

• Chemical Processing: Due to its superior corrosion resistance, titanium blind flanges are commonly used in chemical processing plants where exposure to corrosive chemicals is prevalent.
• Marine and Offshore: Ideal for marine environments and offshore platforms where resistance to seawater corrosion is critical.
• Aerospace: Used in aerospace applications for their lightweight properties and resistance to high temperatures and pressures.
• Oil and Gas: Suitable for oil and gas industries where high strength, corrosion resistance, and reliability are required in pipeline systems.

6. Packages of Titanium Blind 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.
