Grade 2 6mm 8mm Titanium Tube for Commercial Heat Exchangers

3AL – 2.5V Grade 2 6mm 8mm Titanium Tube used in Commercial Heat Exchangers
 
Introduction of Titanium Tube Grade 2:
Grade 2 titanium tubes are extensively used in commercial heat exchangers due to their outstanding corrosion resistance and robustness. They are chosen for applications where maintaining structural integrity and withstanding harsh operating conditions are paramount concerns. These tubes are favored in industries such as chemical plants, oil and gas production, and various industrial processes where durability and reliability are crucial.

In contrast, grade 9 titanium tubes are highly valued in aerospace for hydraulic lines because of their exceptional combination of lightweight properties and high strength. This grade of titanium is also widely adopted in motorsports, sports equipment, and bicycle manufacturing. The lightweight nature of grade 9 titanium contributes to improved performance in applications requiring quick acceleration and deceleration, such as in sports shafts like those used in golf clubs and lacrosse sticks.

For motorcycle exhaust tubing, grade 9 titanium is suitable for applications where temperatures remain below 800 degrees Fahrenheit, offering durability and corrosion resistance in demanding environments. However, in auto racing headers, which experience temperatures exceeding 1000 degrees Fahrenheit, the feasibility of using titanium is still under exploration due to its operational temperature limits.

These titanium tubes are available in a range of sizes from 1/4″ OD up to 6″ OD and conform to various specifications including AMS-4941, 4942, BMS-7-21, DMS-1872, 1874, 1898, AMS-4943, 4944, 4945, DMS-2241, B50TF35, and PWA-1260. Their versatility extends to applications such as funny car body trees, wheelchairs, tennis rackets, drive shaft tunnel supports, wheelie bars, suppressors, and heat exchangers across different industries.

Different Grades of Titanium:

Titanium is a versatile metal known for its exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility. There are several grades of titanium, each with unique properties and applications. Here’s an overview of some common grades:
 
Grade 1 Titanium (Ti-1, CP-1):

• This is the most ductile and softest grade of titanium.
• It offers excellent corrosion resistance in highly oxidizing environments.
• Used in chemical processing, marine, and aerospace applications where formability and corrosion resistance are critical.
• Typically used in applications where ductility and cold formability are required.

 
Grade 2 Titanium (Ti-2, CP-2):

• Commercially pure titanium with moderate strength.
• Excellent corrosion resistance similar to Grade 1 titanium.
• Good weldability and formability.
• Commonly used in industrial applications such as heat exchangers, chemical processing equipment, and marine hardware.

 
Grade 5 Titanium (Ti-6Al-4V):

• An alloyed titanium grade containing 6% aluminum and 4% vanadium.
• High strength, good corrosion resistance, and excellent toughness.
• Widely used in aerospace, marine, and biomedical applications.
• Known for its light weight and high tensile strength, making it suitable for structural components like aircraft parts and surgical implants.

 
Grade 7 Titanium (Ti-0.15Pd):

• Alloyed with 0.12-0.25% palladium.
• Enhanced corrosion resistance, particularly in reducing and mildly oxidizing environments.
• Used in chemical processing and desalination plants where resistance to corrosion by chlorides is crucial.

 
Grade 9 Titanium (Ti-3Al-2.5V):

• Alloyed with 3% aluminum and 2.5% vanadium.
• Combines moderate strength with good weldability and corrosion resistance.
• Used in aerospace, automotive, and marine applications where lightweight components with high strength are required.
• Also found in sporting goods such as bicycle frames and golf clubs due to its light weight and durability.

 
Grade 12 Titanium (Ti-0.3Mo-0.8Ni):

• Alloyed with 0.3% molybdenum and 0.8% nickel.
• Offers improved corrosion resistance in reducing environments compared to commercially pure grades.
• Used in chemical processing equipment and marine applications where resistance to crevice corrosion is needed.

Each grade of titanium is tailored to specific applications based on its unique combination of properties, including strength, corrosion resistance, weldability, and biocompatibility. The choice of grade depends on factors such as the environment it will be exposed to, required mechanical properties, and manufacturing considerations.

Features of Grade 2 Titanium Tube:

Grade 2 titanium tubes are renowned for their excellent corrosion resistance, making them indispensable in industries where exposure to corrosive environments is common. This grade of titanium, classified as commercially pure titanium, contains minimal alloying elements, primarily consisting of titanium with traces of oxygen, nitrogen, carbon, hydrogen, and iron. It boasts superb weldability and formability, making it suitable for a wide range of applications across various industries.

Key Characteristics of Grade 2 Titanium:

Corrosion Resistance: Grade 2 titanium exhibits exceptional resistance to corrosion in oxidizing and mildly reducing environments. This property is particularly advantageous in chemical processing, marine, and aerospace applications where exposure to moisture, chemicals, and saltwater is prevalent.

Strength and Durability: While not as strong as alloyed titanium grades, grade 2 titanium still offers sufficient strength for many applications. It maintains its mechanical properties at elevated temperatures, ensuring long-term performance under demanding conditions.

Fabrication and Weldability: Grade 2 titanium is readily fabricated into tubes, sheets, plates, and other forms using common manufacturing processes such as welding, machining, and forming. This ease of fabrication contributes to its widespread use in various industrial sectors.

Biocompatibility: Due to its inert nature and biocompatibility, grade 2 titanium is extensively used in medical implants, surgical instruments, and dental applications. It is non-toxic and hypoallergenic, making it suitable for direct contact with human tissues and fluids.

Lightweight: Like all titanium alloys, grade 2 titanium is lightweight, approximately half the density of steel. This property makes it ideal for applications where weight reduction is critical without compromising strength and durability.
