2. Titanium Material

Titanium alloys are known for their excellent corrosion resistance, especially in aggressive environments like seawater, chlorine, and acids. They also possess a high strength-to-weight ratio, making them ideal for aerospace, chemical processing, and offshore applications.

Common titanium alloys used in flanges include Grade 2 titanium (commercially pure titanium) and Grade 5 titanium (Ti-6Al-4V, an alloy with aluminum and vanadium for enhanced strength).

Titanium flanges typically offer corrosion resistance in environments where stainless steels might fail or require more costly and heavier materials.

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:

1. 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.

2. 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.

5. Grades of Titanium:

Titanium weld neck flanges are commonly used in piping systems due to their strength, light weight, and excellent corrosion resistance. These flanges are available in various grades, each tailored for specific applications and environments.

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.

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.

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.

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.

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.

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.

6. 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.
