State of the heat exchanger industry



Heat exchanger in petroleum, chemical, light industry, pharmaceutical, energy and other industrial production, is often used to heat low temperature fluid or high temperature fluid cooling, liquid vaporization into steam or steam condensation into liquid. A heat exchanger is a unit of equipment, such as a heater, a cooler, a condenser, etc. It is also an integral part of a process equipment, such as a heat exchanger in an ammonia synthesis tower. Heat exchanger is an important unit equipment in chemical production, according to statistics, the tonnage of heat exchanger accounts for about 20% of the whole process equipment, some even as high as 30%, its importance can be imagined.

Shell - and - tube heat exchanger is a large quantity and variety of products, the urgent need for new wear resistance, corrosion resistance, high strength materials. In China, the development of stainless steel copper alloy composites, aluminum magnesium alloys and silicon carbide and other non-metallic materials has made progress to varying degrees, especially the rapid development of titanium. Titanium has good corrosion resistance to seawater, chlor-alkali, acetic acid, etc., and the effect will be better if the heat transfer is strengthened again. Some manufacturing units have mastered the processing and manufacturing technology of titanium materials. For material spraying, our country has introduced production lines from abroad. It should be noted that al-mg alloy has high corrosion resistance and thermal conductivity and is cheaper than titanium. In China, remarkable achievements have been made in improving the performance of heat exchangers, improving the heat transfer efficiency, reducing the heat transfer area, reducing the pressure drop and improving the heat intensity of devices. The use of heat exchangers in large quantities effectively improves the utilization rate of energy, reduces the cost of enterprises and improves the efficiency.
