CNNC Technology Becomes the World's Only Company to Master Key Technologies in Nuclear Valve Manufacturing
TapTechNews August 14th news, according to the news of CNNC Technology today, on August 13, 2024, the identification meeting of the pilot safety valve of the pressurizer was held in Chengdu, Sichuan. With the passing of this valve identification meeting, it indicates that CNNC SuFa Technology Industry Co., Ltd. (referred to as CNNC Technology) has the production and manufacturing capacity of the pilot safety valve of the pressurizer, and can be applied and promoted in engineering. It has become the only company in the world that can simultaneously manufacture and produce the main steam isolation valve, the bursting valve, and the pilot safety valve of the pressurizer.
According to the official introduction of CNNC Technology, for a long time, the three types of nuclear power valves, namely the main steam isolation valve, the bursting valve, and the pilot safety valve of the pressurizer, as the key equipment for the safe and stable operation of nuclear power plants, because of their complex technology, difficult manufacturing, harsh operating conditions, and involving multiple fields, have always been strangled by foreign countries and are known as the three pearls on the crown of nuclear power key valves. Just completing the research and development and manufacturing of one of the products requires overcoming many unimaginable difficulties. Many multinational companies with strong strength can only produce and manufacture one or two types of valves.
At the end of 2022, CNNC Technology developed the gas-liquid linkage drive device of the DN1050 main steam isolation valve, conquered the most complex core technical difficulty of the main steam isolation valve, and realized the whole machine localization engineering application. At the same time, CNNC Technology successfully achieved the localization and large-scale production of the bursting valve.
With the completion and passing of all the identification experiments of the pressure regulator pilot safety valve, which is recognized as the most difficult equipment to be localized in the nuclear valve industry, it represents that China has completely mastered the key technology of this nuclear power valve, broken the monopoly, has the ability to independently supply to nuclear power units and becomes one of the few countries in the world that masters this technology.
TapTechNews inquired and learned that the former of CNN C SuFa Technology Industry Co., Ltd. was Suzhou Iron Factory (later changed to Suzhou Valve Factory) established in 1952. It is a technology-based manufacturing enterprise integrating the research and development, design, manufacturing and sales of industrial valves. The company was listed on the Shenzhen Stock Exchange in 1997 and became the first listed enterprise in the valve industry in China and under China National Nuclear Corporation.
