1.Classification

Titanium tubes are divided into seamless tubes and welded tubes. The welded pipe is made of titanium plate of the same thickness and rolled. The seamless tube is cold rolled from a billet through a rolling mill. Tube blanks are divided into hot-extruded tubes, which have smooth internal surfaces and high cost. They are suitable for heat exchange tubes. The inner wall of obliquely perforated tube blanks is relatively rough. It is suitable for production of general-purpose tubes and can also be used to make tube targets for vacuum coating. titanium).

2. Application

· Pure titanium tubes can be used to produce titanium coils, such as heat exchangers, heating tubes, condenser tubes and tubes on heat exchangers.

· The most commonly used alloy tube is TA10, TA9, TA18, which is stronger than pure titanium and more resistant to corrosion. TA18 (3Al-2.5V) (good corrosion resistance and high strength) is often used to process titanium alloys Bicycle frame.

· Seamless tubes represented by TC4 / GR5 (Ti-6Al-4V), TC11, TC18 in alloy tubes. Due to the hard material, drilling and hot extrusion technologies are generally used, mainly for petroleum logging, aerospace, and deep sea. Pressure-resistant equipment, etc.

· Welded pipes are mostly pure titanium pipes, which are generally used in power plant water treatment equipment and seawater desalination systems.
