The finned heat exchanger tube for nuclear power successfully developed by ZJRQ Energy-saving Technology Co., Ltd. has a patent and passed the expert review organized by the China Machinery Industry Federation, and will be put into use soon. This important component not only breaks the monopoly of foreign countries, but also has higher heat exchange efficiency and safety level, which is an important step for the localization of key nuclear power equipment in China.
Finned heat exchange tubes are the core components of steam-water separation reheaters for nuclear power plants, while nuclear power steam-water separation reheaters are an important part of conventional islands in nuclear power plants, known as the "kidney of nuclear power." At present, the conventional model used by all nuclear power plants in China is 27 fin heat exchange tubes per inch, all imported from abroad, which not only poses a threat to energy security, but also has a long delivery time and extremely high cost.
The company has been transforming and upgrading since 2011, and is committed to the research and development of TP439 fin heat exchanger tubes for nuclear use. It was successfully developed in 2015 and successfully passed the technical appraisal organized by the China Machinery Industry Federation and obtained the technical achievement appraisal certificate. As a result, it became the third company in the world and the only company in the country with the ability to design and manufacture the product.
