Gr2 Titanium Pipe Usefull in Pipeline
Gr2 titanium tubing has high strength and low density, which makes the tubing both strong and lightweight, and reduces the burden of installation and maintenance.
Description
What Is ASTM B338 Grade 2 Titanium Tube?
Grade 2 Titanium Tube is a commercially pure titanium tube manufactured according to ASTM B338 / ASTM B861 standards with the material designation UNS R50400. It offers an excellent balance of corrosion resistance, strength, weldability, and cost-effectiveness, making it the most widely used commercially pure titanium grade for industrial applications.
GR2 titanium tubes are commonly used in heat exchangers, condensers, seawater cooling systems, desalination equipment, and chemical processing industries where long service life and reliable performance are required.
Applications of Gr2 Titanium Pipe
1. High temperature and high pressure environment: In high temperature and high pressure environment, Gr2 titanium tubing can still maintain good performance, suitable for reactor feed piping, heater outlet piping and so on.
2. Cooling system: used for cooling system piping, improve the efficiency and reliability of the cooling system.
3. Heat exchanger: used as tube bundles in heat exchangers to improve heat exchange efficiency and corrosion resistance.
