Titanium Fin Tube
Titanium fin tubes are a type of heat exchanger used in many industries. They are made of titanium. The fins increase the surface area of the tubes, which allows them to transfer heat more efficiently and the weight is light compare with other materials. This makes them ideal for applications where high heat transfer rates are required.
Finned tubes are used in applications that involve the transfer of heat from a hot fluid to a colder fluid through a tube wall. They are used in condensers, coolers, and furnaces. The larger surface area means that fewer tubes are needed compared to the use of plain tubes.
The type of finned tube is chosen depending on the specific requirements of each process equipment unit. The fin type and combination of materials are chosen based on the specific requirements of each process equipment unit.

Description
Titanium fin tubes are widely used in a variety of heat exchanger applications worldwide. These applications cover many industries such as steam turbine power plant, refineries, chemical plants, air conditioning systems, multi-stage flash distillation, desalination and vapor compression plants, offshore platforms, surface ships and submarines, as well as swimming pool heating systems. The popularity of titanium tubes results from several fundamental reasons:
1. Excellent Corrosion Resistant
Due to the high affinity of titanium to oxygen and moisture in the air, a highly stable, tenacious and permanent thin oxide film (TiO2) forms on the metal surface and immediately regenerates after being damaged. This property explains the excellent corrosion resistance of titanium to a plurality of harsh environments such as oxidizing chloride solutions, acetic and nitric acids, wet bromine, and acetone. Titanium is further very stable in formic, citric, tartaric, stearic, and tannic acids. Alkaline environments up to pH 12 and 75°C usually offer no problem for titanium. Titanium is used in areas in which austenitic stainless steels no longer provide sufficient corrosion resistance.
For heat exchangers in which the cooling medium is seawater, brackish water, or polluted water, commercially pure titanium tubes have demonstrated their superior corrosion resistance for decades. Usually titanium requires no corrosion allowance, so often the higher up-front costs are compensated soon by less down time and reduced maintenance costs.
2. Proper Mechanical and Physical Properties
The thermal conductivity of titanium is roughly 50% higher than for stainless steel. It makes titanium a preferred material for heat exchangers. The high specific strength (strength-to-weight ratio) characterizes titanium for some applications where less mass are required. Engineering experiences have shown that titanium exhibits good erosion resistance. Even water speeds of 10 m/s do not cause any erosion corrosion, cavitation, or impingement attack in the tubes. Thus, thin-walled heat exchanger/ condenser tubing can often be used with zero corrosion allowance.
