Huaxia Valve attaches great importance to the development of CGNPC 45C project

China Instrument Network Instrument Development In the afternoon of April 25th, Huaxia Valve conducted nuclear power product simulation for more than 50 related personnel who participated in the high-end gate valve project of LOT45C conventional islands of Unit 5-6 of Hongguanghe Nuclear Power Station Hongyanhe Nuclear Power Station. The manufacturing technology and process training and submission will prepare the company for the official launch of the CGNPC 45C nuclear power project in September.


The CGNPC 45C project is the first major nuclear power project for Huaxia Valve. It has high requirements for operators, inspectors, and design and craftsmen. Any mistakes and mistakes will be costly. As a newcomer to the nuclear power industry, the company has placed more emphasis on the project than ever before. In addition to adjustments, enhancements, additions, and improvements in personnel, equipment, and the environment, it was also determined that the DN450 gate valve project of the “Shangguo” Sacred Project be conducted as a simulation of nuclear power product processing in advance, from design, inspection, data, Various processes such as the manufacturing process test whether the company's processes, systems, management work, and methods are suitable for nuclear power requirements, so as to expose various problems and process them before formal production.

To this end, the company organized technical presentations and training sessions on the afternoon of April 25, and the technical department Chen Rongchang and Bai Keyou provided training and presentations on design drawings and process manufacturing. Among them, Chen Rongchang focused on three aspects including the standards involved in the design drawings, the dimensions of the key parts of the design drawings, and the dimensional accuracy of the design, combined with the company’s existing equipment to provide technical explanations and notes, and performed a more in-depth study. Communication and discussion. Bai Keyou conducted the craftsmanship from the manufacturing process of each part and the different quality control of conventional valves.


Chen Rongchang stated that the CGNPC 45C nuclear power project is of great importance and the production department must strictly follow the design drawings. Therefore, the size of the design drawings cannot be any mistakes, and can be achieved once and for all at once. This time, it is hoped that the relevant departments and personnel will be highly vigilant and valued. The second is to allow the production and quality departments to digest and absorb and then feedback according to the actual situation, so that the technical department can modify and adjust the drawings in a timely manner to make the drawing process more suitable. Production and data preparation are more practical.
