Titanium Tube Heat Exchanger

1 the application of titanium in chemical industry

titanium and titanium alloy, not only the large strength, good toughness and weldability, more important is that it has excellent corrosion resistance.In oxidizing, neutral and chloride ions in the medium of its corrosion resistance in some places more than ten times or even dozens of times of SUS304 stainless steel. Thus since the 1980 s in China, is widely used in alkali, salt, urea, pesticide, synthetic fiber, organic synthesis, pharmaceutical, hydrometallurgy, such as chemical process industry.

2 application of titanium tube heat exchanger in the oil refining chemical. 

titanium  has excellent corrosion resistance, high specific strength and good processing performance, thus is earlier used in the oil refining chemical industry, in the United States, Europe, Japan, titanium has been used more than 40 years, has nearly 20 years in China.

Titanium CN is mainly used in cooler, heat exchanger, condenser, and in not only apply to the water cooler, can also be applied to oil and gas heat exchanger;Not only can be used in the new system of titanium heat exchanger, also can be used as a technical modification for titanium pipe to replace copper tube coolers (still with a brass plate).

Japan since 1955 in titanium solve atmospheric and vacuum low-temperature H2S corrosion - HCl - H2O environment problems.Europe and the United States as early as in 1960 will also titanium heat exchanger used in refineries, initially mainly to solve the corrosion of seawater, brackish water and polluted water, and then used to prevent the lower quality of crude oil and corrosive gas corrosion of equipment.Due to domestic in recent years, many imported crude oil from the Middle East, and high sulfur content of crude oil, this brings the refining equipment to improve the technical transformation of material, to adapt to the refining high sulphur crude oil in the Middle East the anti-corrosion requirements.Domestic crude oil with the increase of production, the sulfur acid salt is increasing, the diversity of oil source and inferior, make the equipment corrosion problems more outstanding, improve the material standards, selection of titanium manufacture certain key sectors severe corrosion of heat exchange or condensing cooling equipment, oil refining chemical plant is one of main measures of energy saving and efficiency.
