EN1092-01 Titanium Plate Slip On Flange Gr1 Gr2 Gr5 Gr7 Flange Pipe Plate PN 16 For Oil And Gas Industry

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. 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.

5.Titanium Plate Flanges Certificates:

Titanium plate flanges typically adhere to various international standards and may require certification to ensure compliance with quality and safety requirements. Common certificates for titanium plate flanges include:

Material Certificates: These certify the composition and properties of the titanium used, ensuring it meets specified standards such as ASTM or EN requirements for purity, mechanical properties, and corrosion resistance.

Dimensional Certificates: These certify that the flanges meet precise dimensional specifications as per standards like EN1092-01 or ASME B16.5, ensuring they fit and function correctly within the piping system.

Pressure Rating Certificates: These confirm that the flanges have been tested and rated to withstand specific pressure levels, such as PN 6, PN 10, PN 16, etc., or ANSI class ratings in accordance with ASME standards.

​Quality Management System Certificates: Such as ISO 9001, which ensures that the manufacturer has implemented and maintains a quality management system that meets international standards for consistency and quality assurance.

Testing Certificates: These may include certificates for non-destructive testing (NDT) methods like ultrasonic testing (UT), radiographic testing (RT), or dye penetrant testing (PT), ensuring the integrity of welds and overall construction.

Corrosion Resistance Certificates: Especially relevant for titanium, these may demonstrate the material's resistance to specific corrosive environments, such as seawater or chemical exposures.
