DIN 2503 Titanium Blind Plate Flange PN 25 Gr2 Gr5 Pipe Plate Flange for Industrial Applications

2. Grades of DIN 2503 Titanium Plate Flange 

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 Plate Flanges in the Applications?

Titanium plate flanges are chosen in various industries primarily due to their unique properties and advantages that make them suitable for specific applications where other materials may not perform as effectively. 

Titanium exhibits exceptional corrosion resistance, especially in aggressive environments such as seawater, chemical processing, and marine applications. This resistance to corrosion helps extend the lifespan of equipment and reduces maintenance costs.

Titanium has a high strength-to-weight ratio, making it significantly stronger than many other metals such as stainless steel or aluminum alloys while being much lighter. This property is crucial in aerospace, marine, and automotive industries where weight savings are critical.

Titanium is biocompatible and non-toxic, making it ideal for medical implants such as orthopedic implants and surgical instruments. It integrates well with the human body and minimizes the risk of adverse reactions.

​Titanium retains its mechanical properties at elevated temperatures, making it suitable for applications where thermal stability is required. This includes aerospace components and industrial processes involving high heat.

​Titanium has a low coefficient of thermal expansion, similar to stainless steel. This property helps maintain dimensional stability in various temperature conditions, ensuring reliability in critical applications.

​Titanium is known for its durability and long service life, even in harsh operating conditions. This makes it a cost-effective choice over the long term, despite its higher initial cost compared to some other materials.

Titanium plate flanges are preferred in industries where their unique combination of properties is essential, such as aerospace, chemical processing, desalination plants, and offshore oil rigs.

5. Different Face Types Of Titanium Plate 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.

6. Applications of DIN 2503 Titanium Plate Flange

• Pipeline Construction: Used to join sections of pipelines, ensuring secure and leak-free connections during fluid transport.
• Refineries and Petrochemical Plants: Installed in processing units for connecting vessels, reactors, and heat exchangers, where resistance to corrosive chemicals is essential.
• Offshore Platforms: Employed in offshore drilling rigs and production platforms to withstand marine environments and harsh weather conditions.
• Gas Processing Facilities: Utilized in compressors, pumps, and valves to maintain operational integrity and safety.
