Titanium tube

The titanium tube is light in weight, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment, such as tube and tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and transportation pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units.

Titanium pipes implement two national standards according to the different requirements and performance: GB/T3624-2010　GB/T3625-2007 ASTM B337 338

Supply grades: TA0, TA1, TA2, TA9, TA10, BT1-00, BT1-0, Gr1, Gr2, GR7, GR18
