1. Heat transfer tubes: GR2 Titanium round tubes are used to manufacture heat transfer tubes for condensers. These heat transfer tubes separate the hot medium from the cooling medium to realize efficient heat exchange.
2. Shells: In some designs, straight GR2 titanium tubes can also be used to make condenser shells, ensuring the corrosion resistance and stability of the whole unit.
3. Connectors: GR2 Titanium seamless tubes are used to make the connectors in the condenser to ensure tight connections and sealing between the various components.

 

GR2 Titanium Round Tube Production Process

 

Titanium tubes are available in both seamless and welded designs. The best choice depends on application requirements such as pressure, tube size, operating environment, and project budget.

	Seamless Titanium Tube	Welded Titanium Tube
Manufacturing Method	Extrusion and cold drawing process without welding	Titanium strip forming followed by longitudinal welding
Weld Seam	No weld seam	Welded joint with controlled welding quality
Strength & Reliability	Higher structural consistency	Excellent performance after welding inspection
Pressure Capability	Suitable for higher pressure applications	Suitable for standard pressure applications
Size Flexibility	Limited by manufacturing process	Available in larger diameters and longer lengths
Wall Thickness	Suitable for various wall thickness requirements	Excellent for thin-wall tube production
Cost	Higher due to complex production process	More economical for large-volume projects

1. What is GR2 Titanium Seamless Tube?

GR2 Titanium Seamless Tube is a commercially pure titanium tube manufactured according to ASTM B861 with the material designation UNS R50400. It is produced without a welded seam and offers excellent corrosion resistance, strength, and reliability for condensers, heat exchangers, and industrial piping systems.

 

2. What standard is used for GR2 Titanium Seamless Tube?

GR2 Titanium Seamless Tube is commonly supplied according to:

ASTM B861 – Titanium and Titanium Alloy Seamless Pipe

ASME SB861 – Titanium and Titanium Alloy Seamless Pipe

Material certification such as EN 10204 3.1 MTC can be provided.

 

3. Why is GR2 Titanium Tube used for condensers?

GR2 titanium tube is widely used for condensers because of its:

Excellent seawater corrosion resistance

High resistance to chloride environments

Long service life

Low maintenance requirements

Reliable performance in heat transfer systems

 

4. What is the difference between GR1 and GR2 Titanium Tube?

GR1 and GR2 are both commercially pure titanium grades. GR1 offers higher ductility and better formability, while GR2 provides higher strength with an excellent balance of corrosion resistance, weldability, and cost, making it the most commonly used industrial titanium grade.

 

5. What sizes of GR2 Titanium Seamless Tube can you supply?

We can supply GR2 seamless titanium tubes in customized sizes, including:

Outside Diameter: 6 mm – 219 mm

Wall Thickness: 0.5 mm – 20 mm

Length: Standard and customized lengths available

Special dimensions can be manufactured according to customer drawings.

 

6. What is the difference between seamless and welded titanium tubes?

Seamless titanium tubes are produced without a weld seam, providing higher structural consistency and pressure resistance. Welded titanium tubes offer advantages in larger diameters, cost efficiency, and faster production.

For critical pressure applications, seamless tubes are usually preferred.
