[0002] Titanium heat exchanger is a heat exchange device made of high-quality titanium tubes that transfers part of the heat of hot fluid to cold fluid. Titanium heat exchanger, with many advantages of industrial pure titanium, is a general equipment in chemical, petroleum, power, food and many other industrial sectors, and occupies an important position in production.
