Titanium Plate Flange Flat DIN Standard Gr1 Gr2 Gr5 PLRF Flange Pipe Flange Plate for Piping Systems

1. Titanium Plate Flange Flat DIN Standard:

DIN Standards: The flanges adhere to the German Institute for Standardization (DIN) standards, which outline specific dimensions, materials, and testing procedures to ensure consistency and reliability. The most common DIN standards for flanges include DIN 2573, DIN 2576, DIN 2631, among others.

Flat Flange: A flat flange typically has a flat face or surface for bolting to the mating flange, creating a strong and tight connection. It is often used in low-pressure systems.

2. Grade Specifications:

Grade 1 (Gr1):

• Material: Commercially pure titanium (99.5% purity), offering excellent corrosion resistance and good ductility. It is suitable for applications with low to moderate stress and where corrosion resistance is a priority.
• Applications: Commonly used in highly corrosive environments like chemical processing, marine environments, and some medical applications.

Grade 2 (Gr2):

• Material: Also a commercially pure titanium alloy (99.2% purity), offering a good balance of strength, ductility, and corrosion resistance.
• Applications: Used in a wide range of applications, including aerospace, marine, and chemical industries, where moderate strength and high corrosion resistance are required.

Grade 5 (Gr5):

• Material: Ti-6Al-4V alloy, which contains 6% aluminum and 4% vanadium. This is the most widely used titanium alloy due to its high strength and excellent corrosion resistance.
• Applications: Gr5 titanium flanges are used in high-stress environments such as aerospace, medical implants, and industrial piping systems. Its high strength-to-weight ratio makes it ideal for these applications.

PLRF Flange:

• PLRF (Plate Raised Face): This refers to a flange type where the sealing surface is raised above the bolt circle to create a tighter seal. The raised face helps to create a better connection, preventing leaks by concentrating the sealing pressure at the point where the flange mates with the gasket.

Use in Piping Systems:

• Piping System Role: These titanium plate flanges (Gr1, Gr2, Gr5) are typically used to join sections of pipes together. They are bolted to the corresponding flange of another pipe section, a valve, or another component. The flange and gasket work together to ensure a leak-proof seal.
• Corrosion Resistance: Titanium is highly resistant to corrosion, especially in aggressive environments, such as chemical or marine systems, making these flanges ideal for such applications.
• Strength-to-Weight Ratio: Titanium’s lightweight nature makes it advantageous in systems where reducing weight is important, such as in aerospace or high-performance machinery.

3. Specifiactions of DIN Flanges:

DIN flanges are flanges that comply with the German Institute for Standardization (Deutsches Institut für Normung, abbreviated DIN) standards. These standards define the dimensions, materials, and testing procedures of flanges, ensuring consistency and reliability in pipeline connections. DIN flanges are widely used in industries such as chemical, power, shipbuilding, and aerospace due to their high quality and precise design.

DIN flanges come in various types, each suitable for different applications. For example, the DIN 2573 standard specifies weld neck flanges for low-pressure applications. These flanges have a long neck that distributes stress more effectively; the DIN 2576 standard defines blind flanges, which are used to close the ends of pipes or valves; the DIN 2631 standard specifies flat face flanges (FF), typically used with gaskets for low-pressure applications; the DIN 2632 standard defines raised face flanges (RF), with a raised area that helps create a tighter seal with the gasket; the DIN 2633 standard covers ring-type joint flanges (RTJ), typically used in high-pressure systems that require a metal-to-metal seal.

Key specifications of DIN flanges include: nominal diameter (DN), which refers to the flange's nominal size and typically corresponds to the pipe's inner diameter, for example, DN50 indicates a flange for a pipe with a 50mm internal diameter; pressure rating, which refers to the maximum pressure a flange can withstand, determined by the material and flange size; bolt circle diameter (BCD), the diameter of the circle through the center of the bolt holes; number of bolt holes, which typically ranges from 4 to 12, depending on the flange size; bolt hole size, the diameter of the bolt holes, which must match the bolts used for installation; flange thickness, which depends on the pressure rating and size; face type, which refers to the surface of the flange that contacts the gasket, available in flat face (FF), raised face (RF), or ring-type joint (RTJ), depending on the flange type; and outer diameter, the maximum diameter of the flange.

DIN flanges are made from various materials, typically including carbon steel, stainless steel, alloy steel, titanium, and nickel alloys. The choice of material depends on the specific requirements of the application. For example, DIN 17100 applies to carbon steel flanges, DIN 17440 applies to stainless steel flanges, and DIN 50304 applies to alloy steel flanges.

DIN flanges are categorized by their PN (pressure rating), which indicates the maximum pressure a flange can withstand. Common pressure ratings include PN 6 (maximum pressure 6 bar), PN 10 (maximum pressure 10 bar), PN 16 (maximum pressure 16 bar), PN 25 (maximum pressure 25 bar), PN 40 (maximum pressure 40 bar), and higher ratings like PN 63 and PN 100, suitable for high-pressure systems.

Flange faces also come in different types, such as flat face (FF), raised face (RF), and ring-type joint (RTJ), which are used in conjunction with gaskets to ensure sealing. The choice of flange face type is crucial depending on the application.

In addition, the design of DIN flanges also takes into account the requirements for matching bolts and gaskets. The bolts must match the size of the bolt holes, typically made from high-strength steel or stainless steel to ensure sealing and fastening; gaskets are used to ensure the flange-to-flange seal, and common gasket materials include rubber, graphite, PTFE (polytetrafluoroethylene), and metal materials, depending on the working conditions and characteristics of the medium.

Finally, DIN flanges typically have important information marked on their surfaces, such as the manufacturer's logo, material grade, pressure rating, dimensions, nominal diameter (DN), and DIN standard number to ensure quality and traceability. Additionally, DIN flanges undergo rigorous quality testing during manufacturing, including pressure tests, material testing, and dimensional inspections, to ensure they meet the expected requirements.

By adhering to DIN standards, manufacturers can ensure the consistent quality of flanges worldwide, ensuring that flanges from different manufacturers fit perfectly together and meet the needs of various industrial piping systems.

5. Benefits of Titanium Weld Neck Flanges:

High Strength-to-Weight Ratio: Titanium is both lightweight and strong, making it useful for reducing the overall weight of piping systems while maintaining strength.

Superior Corrosion Resistance: Titanium is especially effective in aggressive and high-temperature environments, such as those found in chemical, marine, and aerospace applications.

Durability and Longevity: Titanium flanges have a long service life due to their ability to resist corrosion, scaling, and wear, resulting in less frequent maintenance and replacement.

High-Temperature Resistance: Titanium can perform in a wide range of temperatures, including both cryogenic and high-temperature conditions, making it suitable for a variety of industrial applications.

Seamless and Strong Welds: The weld neck design ensures that the connection between the flange and pipe is strong and provides a smooth transition to avoid stress concentration.
