2. Product Information of Titanium Weld Neck Flange
A titanium weld neck flange, which conforms to ANSI B16.5 standards, is a highly specialized flange used primarily for its exceptional strength, corrosion resistance, and durability. This type of flange is designed to be welded to the end of a piping system, providing a robust and secure joint essential for high-pressure applications. Here's a detailed introduction to the features and benefits of titanium weld neck flanges:
Material and Construction
- Material: Typically manufactured from titanium, with Grade 2 (commercially pure) and Grade 5 (Ti-6Al-4V alloy) being the most common due to their excellent balance of strength, ductility, and corrosion resistance.
- Design: The flange’s neck, which is welded to the pipe, gradually transitions in thickness from the flange to the pipe wall. This provides important reinforcement at the joint and distributes stress more efficiently.
Features
- Corrosion Resistance: Titanium is exceptionally resistant to both oxidizing and reducing environments, which makes it ideal for use in chemical processing, chlorine-related industries, and offshore oil and gas platforms.
- High Strength-to-Weight Ratio: Titanium flanges are lighter than their steel counterparts, yet they offer comparable or superior strength, making them suitable for aerospace and military applications.
- High Temperature Performance: Titanium maintains its strength at high temperatures better than many other metals, suitable for high-temperature processes.
Standards and Specifications
- Compliance with ANSI B16.5: This standard covers dimensions, tolerances, marking, and material requirements for pipe flanges in sizes from 1/2" to 24" and ratings from Class 150 to Class 2500.
- Pressure Ratings: Available in various pressure classes to suit different system pressures and operational requirements.
3. ASME B16.5 Grade 2 Titanium Industrial Flanges WNRF Class150
Grade 2 titanium flanges are renowned for their high strength and exceptional corrosion resistance. Titanium, as an active element, readily reacts with oxygen in the air to form a dense oxide film on its surface. This titanium oxide layer possesses robust hardness and corrosion resistance properties, effectively preventing further reactions with other chemical elements.
To enhance these properties further, our titanium products undergo a specialized pickling treatment. This treatment involves soaking the titanium in a carefully formulated solution of nitric acid and hydrofluoric acid. The pickling process serves several critical purposes:
-
Surface Smoothing: It smooths the surface of the titanium, ensuring it meets stringent surface finish requirements. This smoothness not only enhances the aesthetic appeal but also promotes better sealing when the flange is installed.
-
Thickening of Oxide Layer: The pickling solution increases the thickness of the titanium oxide film on the surface. A thicker oxide layer contributes significantly to the flange's corrosion resistance capabilities, providing superior protection against corrosive environments.
By meticulously controlling the pickling process, we optimize the performance of Grade 2 titanium flanges for applications where corrosion resistance is paramount. Whether used in chemical processing, marine environments, or other demanding industries, our titanium flanges reliably maintain their integrity and functionality over extended periods.

6. Applications of ANSI B16.5 Titanium Weld Neck Flange
Titanium weld neck flanges are used in various industries including petrochemical, oil and gas, power generation, bulk liquid transportation, chemicals, pharmaceuticals, pulp and paper manufacturing, textiles and others.
7. Titanium Weld Neck Flange Inspections
Visual Testing (VT): This involves inspecting the surface of the weld and the flange visually to detect any visible defects such as cracks, porosity, or improper weld profiles.
Ultrasonic Testing (UT): This technique uses high-frequency sound waves to detect internal defects within the material, such as voids, inclusions, or cracks. It's particularly useful for thicker sections of titanium welds.
Radiographic Testing (RT): This method uses X-rays or gamma rays to produce images of the internal structure of the weld and flange. It's effective for detecting internal defects and assessing weld quality.
Magnetic Particle Testing (MT): MT is used to detect surface and near-surface defects in ferromagnetic materials. However, since titanium is not ferromagnetic, this method might not be applicable unless there are magnetic materials nearby or coatings that can be magnetized.
Penetrant Testing/Dye Penetrant (PT): PT involves applying a dye penetrant to the surface of the weld and then removing excess dye to reveal surface-breaking defects. This method is useful for detecting small cracks, porosity, and leaks.
Eddy Current Testing (ET): ET uses electromagnetic induction to detect surface and near-surface defects in conductive materials like titanium. It's useful for detecting corrosion, cracks, and variations in material properties.
Acoustic Emission (AE): AE involves monitoring the acoustic emissions from a material under stress to detect changes indicative of defects like cracks or leaks. It can be used for both weld and base material inspection.
