Titanium alloy tube

Titanium and titanium alloy tubes are light in weight, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and pipelines, etc. According to customer requirements, high-precision, large-diameter titanium and titanium alloy pipes, titanium seamless pipes, and titanium welded pipes can be provided. the
