Titanium tube has the advantages of light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, coil heat exchanger, condenser, evaporator and transmission pipeline. Many nuclear power industries take titanium tubes as the standard tubes for their units.
