1.Product Introduction of DIN2634 Titanium Weld Neck Flange

A weld neck flange is a type of flange designed to be welded onto the end of a pipe or fitting. It has a long tapered neck (or hub), which transitions gradually to the pipe or fitting it is welded to. The flange itself is typically made from materials such as titanium, stainless steel, or carbon steel, depending on the application's requirements. Weld neck flanges are preferred in applications where high pressure, temperature fluctuations, or severe service conditions require a robust and leak-free connection. They are especially suitable for critical applications in industries such as oil and gas, chemical processing, power generation, and aerospace.

 

The DIN 2634 PN25 flange, also known as a welding neck flange, is designed for use in conditions where temperatures reach up to 120 degrees Celsius, and it can withstand pressures of up to 25 bar. It's crucial to note that at higher temperatures, materials can experience a decrease in their strength properties. This type of flange is extensively utilized across various industries such as oil and gas, chemicals, engineering, and petrochemical sectors. Its popularity extends to countries like South Africa, Kenya, and Russia.

 

The dimensions of the DIN 2634 PN25 flange include key elements such as the pipe size, flange size, neck length, raised face dimensions, and bolt holes. These specifications adhere to standardized DIN and ISO series, ensuring compatibility and ease of use in diverse piping systems. Reference to a weight chart is essential during manufacturing to ensure the precise fabrication of these flanges.

In summary, the DIN 2634 PN25 flange serves as a reliable component in industrial applications requiring robust performance under high temperatures and pressures, contributing to efficient and secure connections in critical infrastructure worldwide.

 

Our Titanium flanges are crafted using various processes including casting, forging, and precision machining to ensure they meet stringent industry standards for quality and durability. Available in customized sizes, these flanges offer easy installation onto pipeline systems and equipment, guaranteeing a secure and leak-free connection.

 

Specifically designed to uphold the highest standards of engineering precision, our Titanium thread flanges excel in performance. They are engineered to resist corrosion effectively and withstand high temperatures and pressures, making them exceptionally suited for demanding environments.

 

Ensuring safe transportation is paramount to us, which is why we meticulously package our Titanium flanges in sturdy wooden cases and pallets. This packaging not only safeguards the flanges during transit but also facilitates easy handling and installation upon arrival.

 

 

 

2. Grades of DIN 2634 Titanium Weld Neck Flange 

DIN 2634 PN 25 Titanium Weld Neck Flange RFWN Gr2 Gr5 Gr12 Raised Face Weld Neck 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

6. Different Face Types Of Titanium Weld Neck Flanges:

Raised Face (RF):

The most common face type for weld neck flanges.

Features a raised portion around the bore with a specific height (typically 1/16 inch) above the flange face.

Provides a surface against which a gasket can seal, ensuring a reliable joint.

Flat Face (FF):

Has a flat face without any protrusion or raised portion.

Typically used in applications where bolt load distribution is critical and where no additional sealing surface beyond the gasket is required.

Requires precision in alignment during assembly to avoid gasket compression issues.

Ring Type Joint (RTJ):

Designed for high-pressure and high-temperature applications.

Features a groove machined into the flange face into which a metal ring gasket is placed.

The flange faces are typically flat with a groove cut into them to accommodate the ring gasket, ensuring a tight seal under extreme conditions.
