Analysis of heat exchanger manufacturers on heat exchangers

Shell-and-tube heat exchanger manufacturers tell you that the 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. my country 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 them, titanium materials have developed rapidly. Titanium has better 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 the performance of heat exchangers, increasing heat transfer efficiency, reducing heat transfer area, reducing pressure drop, and increasing the thermal strength of the device. The extensive use of heat exchangers has effectively improved the utilization rate of energy, lowered the cost of the enterprise, and improved the efficiency.
