EN1092-01 Gr1 Gr5 Gr7 Titanium Plate Flange PN 63 for Pipeline Systems

2. Grades of EN1092-01 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. Benefits of Titanium Plate Slip On Flanges:

Titanium plate slip-on flanges offer several benefits that make them suitable for various industrial applications where titanium's properties are advantageous. Here are some key benefits:

Corrosion Resistance: Titanium is highly resistant to corrosion in a wide range of aggressive environments, including seawater, acids, and chlorides. This property makes titanium slip-on flanges ideal for applications where corrosion is a concern, such as marine environments, chemical processing, and offshore oil platforms.

High Strength-to-Weight Ratio: Titanium is known for its excellent strength-to-weight ratio, which is superior to most other metals. This characteristic allows titanium slip-on flanges to provide strong, durable connections while being lightweight. It's particularly beneficial in aerospace applications and industries where weight reduction is critical.

Biocompatibility: Titanium is biocompatible and non-toxic, making it suitable for applications in medical devices, pharmaceutical production, and food processing where product purity and safety are essential.

High Temperature Resistance: Titanium maintains its strength and corrosion resistance at elevated temperatures, up to around 600°C (1112°F), depending on the grade. This property makes titanium slip-on flanges suitable for high-temperature applications such as heat exchangers and chemical reactors.

Ease of Fabrication: Titanium can be easily machined, welded, and formed, allowing for complex shapes and configurations in slip-on flanges. This flexibility in fabrication facilitates customization and adaptation to specific project requirements.

Longevity and Durability: Titanium is known for its long-term durability and resistance to degradation over time, ensuring a reliable performance and extended service life of slip-on flanges in demanding industrial environments.

5. Titanium Plate Slip On Flange Inspections

Visual Testing (VT): This involves inspecting the surface of the weld and the flange visually to detect any visible defects such as cracks, porosity, or improper weld profiles.

Ultrasonic Testing (UT): This technique uses high-frequency sound waves to detect internal defects within the material, such as voids, inclusions, or cracks. It's particularly useful for thicker sections of titanium welds.

Radiographic Testing (RT): This method uses X-rays or gamma rays to produce images of the internal structure of the weld and flange. It's effective for detecting internal defects and assessing weld quality.

Magnetic Particle Testing (MT): MT is used to detect surface and near-surface defects in ferromagnetic materials. However, since titanium is not ferromagnetic, this method might not be applicable unless there are magnetic materials nearby or coatings that can be magnetized.

Penetrant Testing/Dye Penetrant (PT): PT involves applying a dye penetrant to the surface of the weld and then removing excess dye to reveal surface-breaking defects. This method is useful for detecting small cracks, porosity, and leaks.

Eddy Current Testing (ET): ET uses electromagnetic induction to detect surface and near-surface defects in conductive materials like titanium. It's useful for detecting corrosion, cracks, and variations in material properties.

Acoustic Emission (AE): AE involves monitoring the acoustic emissions from a material under stress to detect changes indicative of defects like cracks or leaks. It can be used for both weld and base material inspection4

6.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.
