Gr2 pure titanium tube refers to a titanium ingot cast from high-purity titanium sponge, which is manufactured by smelting, ковка, drawing of tube blanks, маринование, annealing, annealing straightening, fixed length, dimensional testing, non-destructive testing, и т. д.. High purity titanium tube with good corrosion resistance and mechanical properties。
Titanium tubes are light in weight, high in strength and have superior mechanical properties. It is widely used in heat exchange equipment, such as tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and delivery pipes. Many nuclear power industries use titanium tubes as standard tubes for their units.
