2. ASME B16.5 Grade 5 Grade 7 Titanium Industrial Flanges WNRF Class150

Titanium Grade 5 (Ti-6Al-4V):

Composition: Titanium Grade 5 is an alpha-beta alloy consisting of 90% titanium, 6% aluminum, and 4% vanadium. This composition provides a balance of properties that make it the most widely used titanium alloy.

Strength: It offers excellent strength-to-weight ratio, making it suitable for aerospace, marine, and industrial applications where lightweight strength is critical.

Corrosion Resistance: Grade 5 titanium has good corrosion resistance, although not as high as pure titanium (Grade 1). It is still highly resistant to most environments.

Temperature Resistance: It maintains its properties at elevated temperatures, making it suitable for applications in gas turbines, exhaust systems, and other high-temperature environments.

Applications: Aerospace components (airframes, jet engines), marine equipment, medical implants, automotive components, sports equipment, and industrial machinery.

Titanium Grade 7 (Ti-0.15Pd):

Composition: Titanium Grade 7 is a titanium alloy with 0.15% palladium added, enhancing its corrosion resistance.

Corrosion Resistance: Grade 7 titanium is highly resistant to corrosion in reducing and mildly oxidizing environments, including chlorides. It is more corrosion resistant than Grade 2 titanium.

Weldability: It offers good weldability, making it suitable for applications requiring fabrication and assembly.

Strength: Grade 7 titanium has lower strength compared to Grade 5 but is still adequate for many applications.

Applications: Chemical processing, desalination, marine environments, and other applications where superior corrosion resistance is required. It is also used in medical implants where biocompatibility and corrosion resistance are critical.

4. Why We Choose Titanium Weld Neck Flanges in the Industry?

Titanium weld neck flanges offer a range of advantages that make them highly sought after in various industrial applications where performance and durability are crucial.

Corrosion Resistance: Titanium weld neck flanges are highly resistant to corrosion, even in aggressive environments such as seawater, acids, and chlorides. This makes them ideal for industries like chemical processing, marine, and offshore oil and gas where corrosion resistance is critical.

Strength-to-Weight Ratio: Titanium has a high strength-to-weight ratio, making titanium weld neck flanges strong and durable while remaining lightweight. This is advantageous in applications where weight reduction is desirable without compromising strength and performance.

High Temperature Resistance: Titanium weld neck flanges can withstand high temperatures without losing their mechanical properties. They maintain their strength and corrosion resistance at elevated temperatures, making them suitable for applications involving heat and thermal cycling.

Biocompatibility: Titanium is biocompatible and non-toxic, which makes titanium weld neck flanges suitable for use in medical equipment, pharmaceutical manufacturing, and food processing industries where product purity is essential.

Longevity and Durability: Titanium is known for its durability and long service life. Titanium weld neck flanges exhibit excellent resistance to fatigue, erosion, and wear, contributing to reduced maintenance and replacement costs over time.

Excellent Sealing Properties: The smooth surface finish of titanium weld neck flanges, achieved through pickling or machining processes, allows for superior sealing with gaskets or other connecting components. This helps prevent leaks and ensures reliable performance in critical applications.

Compatibility with Other Metals: Titanium weld neck flanges can be easily welded or paired with other metals such as stainless steel or carbon steel, allowing for versatility in design and compatibility with existing systems.

5. Titanium Weck Neck Flanges Certicifates

EN 10204/3.1B Certificate:

This is a standard certificate that confirms compliance with the material specification and provides chemical composition and mechanical properties of the titanium alloy used in manufacturing the flanges. It is issued by the manufacturer and verifies that the material meets the required standards.

Raw Materials Certificate:

This certificate provides details about the raw materials used in the production of the titanium flanges. It includes information such as the origin of the raw materials, their composition, and any applicable material testing results. This ensures traceability and quality control from the initial material procurement stage.

100% Ultrasonic Flaw Detection:

Ultrasonic testing (UT) is a non-destructive testing method used to detect internal and surface defects in the titanium flanges. A 100% UT coverage means that all flanges undergo thorough testing to ensure there are no defects that could compromise their structural integrity or performance.

Hydrostatic Test:

This test involves pressurizing the titanium flange with water or another liquid to a predetermined pressure level. It assesses the flange's ability to withstand pressure without leakage or deformation, ensuring it meets the specified pressure ratings and safety requirements.

Third Party Inspection Report:

This report is conducted by an independent third-party inspection agency or authority. It provides an unbiased assessment of the titanium flanges' quality, confirming compliance with applicable standards, specifications, and customer requirements. It adds credibility to the manufacturer's quality assurance processes.

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.
