The characteristics of shell and tube heat exchanger products
Mar 10, 2021

Shell-and-tube heat exchanger is a large quantity and a wide variety of products, and there is an urgent need for new wear-resistant, corrosion-resistant, and high-strength materials. China has made different degrees of progress in the development of stainless steel copper alloy composite materials, aluminum-magnesium alloys and silicon carbide and other non-metallic materials, among which titanium materials have developed rapidly. Titanium has good corrosion resistance to seawater, chlor-alkali, acetic acid, etc. If heat transfer is strengthened, the effect will be better. Some manufacturing units have better mastered the processing and manufacturing technology of titanium. For the spraying of materials,our country has introduced production lines from abroad.Aluminum-magnesium alloy has high corrosion resistance and thermal conductivity,and the price is cheaper than titanium, so attention should be paid. Remarkable achievements have been made in domestic research on improving heat exchanger performance, increasing heat transfer efficiency, reducing heat transfer area, reducing pressure drop, and improving device thermal strength in energy conservation and efficiency gains.The large-scale use of heat exchangers effectively improves the utilization rate of energy, reduces the cost of the enterprise, and improves the efficiency.
