4. Advantages of DIN86029 Titanium Hubbed Slip On Flanges:

Titanium slip-on flanges offer several advantages that make them highly suitable for various industrial applications:

Corrosion Resistance: Titanium is renowned for its exceptional corrosion resistance, especially in aggressive environments such as seawater, acids, and chlorides. This property ensures longevity and reliability in corrosive industrial settings where conventional materials might fail.

High Strength-to-Weight Ratio: Titanium possesses a superior strength-to-weight ratio compared to steel and many other metals. This characteristic allows titanium slip-on flanges to provide robust performance while being lightweight. It's particularly advantageous in applications where weight reduction is critical, such as aerospace and marine industries.

High Temperature Resistance: Titanium maintains its mechanical properties and corrosion resistance at elevated temperatures, up to around 600°C (1112°F), depending on the grade. This makes titanium slip-on flanges suitable for applications involving high temperatures, such as chemical processing and thermal power generation.

Biocompatibility: Titanium is biocompatible and non-toxic, making it suitable for use in industries such as pharmaceuticals, food processing, and medical devices where product purity and safety are paramount.

Low Thermal Expansion: Titanium has a low thermal expansion coefficient compared to steel, which can reduce the risk of leaks and failures in piping systems due to temperature variations.

Longevity and Durability: Titanium is known for its excellent durability and resistance to degradation over time, ensuring a longer service life and reduced maintenance costs compared to other materials.

Ease of Fabrication: Titanium can be easily machined, welded, and formed into complex shapes, allowing for customized designs and configurations to meet specific project requirements.

Non-magnetic and Non-sparking: Titanium is non-magnetic and non-sparking, making it suitable for applications where these properties are advantageous, such as in sensitive electronic equipment or environments with explosive hazards.

Environmental Compatibility: Titanium is environmentally friendly due to its resistance to corrosion, longevity, and ability to be recycled, reducing its environmental impact over its lifecycle.

5. The Product Process ofDIN 86029 Titanium Hubbed Slip On 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.

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.
