Titanium Heat Exchanger

Product Introduction

Titanium heat exchangers are heat transfer devices using titanium tubes as the core components, designed to transfer thermal energy from hot fluids to cold fluids. Leveraging the exceptional properties of industrial pure titanium, these exchangers serve as critical universal equipment in chemical, petroleum, energy, food, and numerous other industrial sectors, playing a pivotal role in modern production processes.

Core Features of Titanium Heat Exchangers

• Hygienic Safety & Non-Magnetic Advantage
  Titanium’s stable metal ions and non-magnetic properties make it ideal for hygiene-sensitive industries like pharmaceuticals and food processing. It can directly handle sensitive processes such as drug concentration and food sterilization without risk of ion contamination.
• Longevity & Low Maintenance
  Titanium’s inherent resistance to corrosion (e.g., corrosion rate <0.001mm/a in 3.5% NaCl seawater) ensures a service life exceeding 20 years with minimal maintenance. This reduces lifecycle costs by up to 50% compared to conventional materials.
• High Efficiency & Energy Savings
  Titanium tubes offer a thermal conductivity of 22W/(m·K) and thin-wall design (0.5-2mm thickness), providing 30% higher heat transfer area per unit volume than stainless steel. Their low density (4.51g/cm³) also reduces equipment size by 40%, cutting associated pump energy consumption by 25%.

Application Scenarios

Titanium heat exchangers are widely used in:

• Marine Engineering: Seawater aquaculture temperature control, ship cooling systems, offshore platform condensers;
• Chemical & Pharmaceutical: Corrosive media heat exchange (e.g., H₂SO₄, NaOH), pharmaceutical intermediate cooling, food-grade aseptic heat transfer;
• Energy & Environmental Protection: Geothermal energy systems, metallurgical pickling 废液冷却 (pickling waste liquid cooling), electroplating bath temperature control;
• Refrigeration & HVAC: Chiller units, district heating substations, low-temperature energy storage systems.

Chemical Properties of Titanium Heat Exchanger Materials

• General Corrosion Resistance:
  Industrial pure titanium demonstrates superior corrosion resistance in organic compounds, alkaline solutions, and salt solutions, with minimal reactivity. This makes it highly suitable for applications involving non-aggressive media.
• Inorganic Acid Resistance:
  At room temperature, pure titanium shows good resistance to low-concentration inorganic acids such as hydrochloric acid, sulfuric acid, and nitric acid. However, as the concentration of these acids or the operating temperature increases, titanium becomes more reactive, leading to reduced corrosion resistance. Therefore, strict control of medium concentration and temperature is critical during heat exchange processes.
• Organic Acid Resistance:
  Industrial pure titanium maintains excellent corrosion resistance against organic acids like formic acid, oxalic acid, and lactic acid under normal temperature conditions, ensuring reliability in food, pharmaceutical, and chemical processes involving such media.

Heat Compensation Methods

The all-titanium shell and tube heat exchanger offers a much larger heat transfer area per unit volume and better heat transfer performance.

• Floating Head Heat Exchanger:One end of the tube sheet is not connected to the shell and is called the floating head. When the tubes are heated, the tube bundle and floating head can expand and contract axially, eliminating temperature difference stress.
• Fixed Tube Sheet Heat Exchanger:Both ends of the tube sheet are integrated with the shell. When there is a large temperature difference between the two fluids, a compensation ring or expansion joint is welded at an appropriate position on the shell. When the shell and tube bundle expand thermally at different rates, the compensation ring undergoes slow elastic deformation to compensate for the thermal expansion caused by temperature difference stress.
• Tube Heat Exchanger:Each tube is bent into a U shape, with fluid inlets and outlets installed on both sides of the same end. The head is divided into two chambers by a partition plate. Each tube can expand and contract freely to solve the problem of heat compensation.
