2. Grades of DIN 2501 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.

4. The production process of titanium plate flanges

Material Selection:

Titanium Alloy: The process begins with selecting the appropriate titanium alloy based on the application requirements. Common alloys include Grade 2 (Ti-CP), Grade 5 (Ti-6Al-4V), and Grade 7 (Ti-0.15Pd), chosen for their specific mechanical properties, corrosion resistance, and other relevant characteristics.

Cutting and Forming:

Raw Material Preparation: Titanium billets or bars are cut into suitable lengths based on the required flange dimensions.

Forging or Rolling: The titanium material is heated to an optimal temperature and shaped using forging or rolling techniques to form the initial flange blanks. For weld neck flanges, this includes forming the neck and the flange face.

Machining:

Turning and Milling: The forged or rolled titanium blanks undergo precision machining operations. This includes turning to achieve the desired outer diameter (OD) and milling to create the flange face (raised face, flat face, or ring type joint per ASME B16.5 specifications).

Drilling: Holes are drilled into the flange to accommodate bolts and ensure proper alignment with the connecting pipes.

Weld Preparation:

Beveling: The ends of the weld neck flange, especially the area where it connects to the pipe, are beveled to facilitate welding. Proper beveling ensures strong weld joints and effective fusion.

Welding:

Welding Process: Titanium weld neck flanges are typically welded using TIG (Tungsten Inert Gas) welding or similar methods suitable for titanium alloys. Welding is performed with care to maintain a shielded atmosphere (argon or helium) to prevent contamination and oxidation, which can compromise the titanium's corrosion resistance.

Weld Inspection: Post-weld inspection includes non-destructive testing (NDT) methods such as dye penetrant testing or ultrasonic testing to verify the integrity of the welds.

Heat Treatment (if required):

Annealing: Depending on the titanium alloy and specific requirements, annealing or stress-relieving heat treatment may be applied to optimize material properties and reduce residual stresses.

Final Inspection and Testing:

Dimensional Inspection: Each weld neck flange undergoes rigorous dimensional checks to ensure it meets precise tolerances and specifications, including those set by ASME B16.5.

Visual and Surface Inspection: Visual inspections ensure there are no surface defects or imperfections that could affect performance or integrity.

Pressure Testing: Hydrostatic or pneumatic pressure testing may be conducted to verify the flange's pressure integrity and leak resistance under specified conditions.

Surface Treatment and Finishing:

Surface Coating: Depending on the application, surface treatments such as passivation or anodizing may be applied to further enhance corrosion resistance or improve surface finish.

Marking and Identification: Each flange is marked with essential information such as material grade, size, pressure class, and manufacturer identification for traceability.

Packaging and Shipping:

Once inspections and testing are completed satisfactorily, the titanium weld neck flanges are carefully packaged to prevent damage during transport and storage. They are then shipped to customers or distribution centers.

7.Titanium Plate Flange Benefits

High Temperature Performance: Titanium retains its strength and stiffness at elevated temperatures, making titanium plate flanges suitable for applications where high temperatures are encountered. They can withstand thermal cycling and maintain their mechanical properties over a wide temperature range.

Biocompatibility: Titanium is biocompatible and non-toxic, making titanium plate flanges suitable for use in medical devices, pharmaceutical processing, and food handling equipment where cleanliness and safety are paramount.

Longevity and Durability: Titanium plate flanges have a long service life due to their resistance to corrosion, fatigue, and erosion. This durability reduces replacement and maintenance costs, making them a cost-effective choice in the long run.

Compatibility with Other Materials: Titanium plate flanges can be easily welded or bolted to other titanium components or dissimilar materials, facilitating integration into complex systems and structures.

Aesthetic Appeal: Titanium has a unique silver-grey appearance that is aesthetically pleasing, making it suitable for architectural applications where visual appeal is important.

Low Thermal Expansion: Titanium has a low coefficient of thermal expansion compared to other metals, which helps maintain dimensional stability under fluctuating temperatures.

Environmental Resistance: Titanium plate flanges exhibit excellent resistance to environmental factors such as UV radiation and saltwater, making them suitable for outdoor and marine applications.

Non-magnetic Properties: Titanium is non-magnetic, which is beneficial in applications where electromagnetic interference (EMI) or magnetic susceptibility must be minimized.
