2. Grades of DIN 2631 Titanium Weld Neck Flange 

DIN 2631 RF WN Titanium Weld Neck Flange Gr2 Gr5 Gr12 WNRF Flange Raised Face PN6 For Industrial Systems 0

 

  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.

    • Titanium: Titanium has exceptional corrosion resistance, especially in aggressive environments such as seawater, chlorides, and oxidizing acids. It forms a protective oxide layer that enhances its resistance to corrosion.
    • Stainless Steel: Stainless steel also offers good corrosion resistance, but not to the extent of titanium. It may require additional coatings or treatments for enhanced protection in corrosive environments.
    • Carbon Steel: Carbon steel is susceptible to corrosion, particularly in moist or acidic conditions, and requires coatings or alloys for protection.
    • Inconel: Inconel alloys provide excellent resistance to oxidation and corrosion in extreme environments, including high-temperature and pressure conditions

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

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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. Different Face Types Of Titanium Weld Neck Flanges:

Raised Face (RF) Flange:

  1. Design:

    • Raised Surface: A Raised Face flange has a small portion around the bore drilled slightly larger than the pipe's diameter. This creates a ridge (or raised face) above the flange's surface.
    • Sealing Surface: The raised face serves as the primary sealing surface where the gasket rests. It provides a tight seal when compressed against the mating flange.
  2. Advantages:

    • Enhanced Sealing: The raised face design concentrates the gasket compression into a smaller area, improving the effectiveness of the seal.
    • Protection: The raised face helps protect the flange surface from damage during handling and installation.
  3. Applications:

    • Common: Raised Face flanges are more common in standard industrial applications where a reliable and leak-free seal is essential.
    • Pressure Ratings: Suitable for higher pressure applications as the raised face allows for better compression of the gasket.

Flat Face (FF) Flange:

  1. Design:

    • Smooth Surface: Flat Face flanges have a flat or smooth surface without any protrusions or raised areas around the bore.
    • Sealing Surface: The sealing is achieved by placing the gasket directly on the flat surface of the flange.
  2. Advantages:

    • Ease of Alignment: Flat Face flanges are easier to align during assembly because there are no raised surfaces to contend with.
    • Space Saving: They require less space compared to Raised Face flanges, which may be advantageous in tight installations.
  3. Applications:

    • Specialized: Flat Face flanges are typically used in low-pressure and non-critical applications where sealing requirements are less stringent.
    • Special Gaskets: May require special gaskets (such as full-face gaskets) that cover the entire face of the flange to ensure proper sealing.

Choosing Between Raised Face and Flat Face:

  • Pressure and Sealing Requirements: Raised Face flanges are preferred for higher pressure applications where a reliable seal is critical. Flat Face flanges are suitable for lower pressure applications or where space constraints are a concern.

  • Gasket Selection: The choice of gasket (such as ring-type or full-face) depends on the flange facing type (RF or FF) and the application requirements for sealing integrity.
