Titanium flanges, crafted from titanium alloys, are highly valued across diverse industries for their exceptional properties. These flanges are renowned for their superb corrosion resistance, high strength-to-weight ratio, and lightweight nature. They excel in harsh environments where chemical corrosion is a concern, making them indispensable in industries such as petroleum, chemical processing, and others requiring robust material performance

• This standard specifies dimensions, tolerances, materials, marking, and testing requirements for pipe flanges and flanged fittings. ASME B16.5 Class 150 denotes a pressure rating of 150 pounds per square inch, which is a common pressure rating for flanges used in lower pressure applications.

1. Titanium Grade 2 (Ti-CP):

   Composition: Commercially pure titanium with a composition of 99.2% titanium, 0.25% iron, 0.3% oxygen, and trace amounts of other elements.

   Corrosion Resistance: Excellent in most environments, especially against chlorides.

   Weldability: Good weldability and fabricability.

   Applications: Chemical processing, marine environments, medical implants (non-load-bearing), and architecture.

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

   Composition: Titanium alloy containing 90% titanium, 6% aluminum, and 4% vanadium.

   Properties:

   Strength: Excellent strength-to-weight ratio, superior to Grade 2 titanium.

   Corrosion Resistance: Good corrosion resistance, not as high as Grade 2 but suitable for many environments.

   Temperature Resistance: Maintains strength at elevated temperatures, making it suitable for aerospace and high-performance applications.

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

3. Titanium Grade 7 (Ti-0.15Pd):

   Composition: Titanium alloy with 0.15% palladium added.

   Properties:

   Corrosion Resistance: Excellent resistance to corrosion, particularly in reducing environments.

   Weldability: Good weldability, suitable for welding and fabrication.

   Strength: Lower strength compared to Grade 5 but adequate for many applications.

   Applications: Chemical processing, desalination plants, marine environments, and other applications requiring superior corrosion.

• 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.
