ASTM B338 / ASME SB338 GR.7 / UNS R52400 TITANIUM SEAMLESS TUBE FOR CONDENSER AND HEAT EXCHANGER
概述：
Gr.7 titanium tubes are made primarily from Grade 7 titanium alloy， which consists of a high percentage of pure titanium (around 99.5%) and a small amount of palladium. The addition of palladium enhances the corrosion resistance and provides improved strength compared to other commercially pure titanium grades.
Gr.7 titanium tubes offer excellent corrosion resistance， particularly in aggressive environments such as seawater， salt solutions， and certain acids. The presence of palladium in the alloy enhances its resistance to corrosion， making it suitable for applications where exposure to corrosive media is expected.
Although Grade 7 titanium is not as strong as some of the titanium alloys， it still exhibits good strength properties， making Gr.7 titanium tubes suitable for applications where both strength and corrosion resistance are essential. The mechanical properties can vary depending on the manufacturing process and heat treatment.
Gr.7 titanium tubes find applications in various industries， including chemical processing， offshore and marine， aerospace， oil and gas， and medical. They are commonly used in heat exchangers， condensers， desalination plants， seawater cooling systems， chemical reactors， and medical implants.
