Thread Content

Witnessing the ten-year rapid development of chemical processing equipment, I admire the prosperity and strength of modern China. Wishing everyone a happy New Year, and may their families enjoy peace and good health. By contributing our ideas, we can create a more lively discussion environment; HaiChuan becomes even better with your participation. Everyone is welcome to join in the forum discussions. ------------------------------------------------- In September 2022, the newly developed ultra-large diameter 60”-150Lb axial flow check valve by CNNC Technology passed its first assembly test in the company’s special valves division, adding another new member to CNNC Technology’s lineup of axial flow check valves. This product is the largest-diameter check valve developed by China National Nuclear Corporation. It features a new type of sealing mechanism, and the manufacturing precision of its components is extremely high, posing challenges at every stage of research, development, and production. To ensure the successful development of the valve from the very beginning, the design and process departments affiliated with China Nuclear Technology Research and Design Institute conducted advance analyses of the challenges involved in every stage of product design and manufacturing, boldly explored new solutions, processes, and methods, and formulated corresponding control plans and safeguard measures. The Oil and Petrochemical Division worked closely together to promote the implementation of control and assurance measures, addressing in advance various key issues that could affect valve quality. With the full support of other relevant departments at China Nuclear Technology, this product achieved excellent results in its first assembly test.
