Gr7 ASTM B338 titanium semaless tube

Grade 7 titanium tube & pipe is an unalloyed titanium, with standard oxygen content and addition of palladium,has excellent corrosion resistance,

So this tube is weidely used in condenser, heat exachger,and water treatment , also used in bicycle frames and other parts .

We supported Water pressure test, UT test, X-ray test, Eddy current test, flaring and flattening test.

Payment terms: T/T, L/C, and customers required.


Grade 7 titanium tube is mechanically and physically the same as CP 2 grade titanium, but due to the addition of palladium to Grade 7 titanium, it is the most corrosion-resistant of all titanium alloys.

Grade 7 titanium tubes are widely used in heat exchange equipment such as tubular heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensing evaporators and transport piping. Many nuclear power industries use Grade 7 titanium tubes as standard tubes for their equipment.
