On February 19, 2024, Hay Think learned from GJZZ that the “Guohe No.1” CAP1400 main pipeline project developed by GJZZ has been recognized as the most technological innovation achievement in the world of heavy-duty machinery in 2023.
“The world’s most scientific and technological achievements” refer to those recognized by the China Heavy Machinery Industry Association, which have achieved or exceeded international advanced levels through independent or collaborative innovation in key technologies. One of the key technical indicators has created and maintained the world’s most scientific and technological achievements in similar products and technologies at the date of recognition. The recognized projects can obtain the world’s most technological innovation achievements special identification and honor.
After evaluation by the expert group, 8 projects nationwide have been recognized as the world’s most scientific and technological achievements. Among them, the “Guohe No.1” CAP1400 main pipeline developed by GJZZ has been recognized as the “world’s largest specification nuclear island primary circuit forged main pipeline”.

It is understood that “Guohe No.1” is a third-generation nuclear power technology with completely independent intellectual property rights in China. The “Guohe No.1” demonstration project is a large-scale advanced pressurized water reactor and high-temperature gas cooled reactor nuclear power plant, and its main pipeline is the “aorta” for the nuclear steam supply system of the pressurized water reactor nuclear power unit to output core heat energy, and it is also a necessary nuclear island key equipment for nuclear power construction.
The application of the “World’s Largest Specification Nuclear Island One Circuit Forged Main Pipeline”, which has been recognized as the “World’s Most Technological Achievement”, to the National Nuclear Power Plant No.1 Demonstration Project is currently the largest, heaviest, most technically demanding, and most difficult to manufacture nuclear island one circuit forged main pipeline in the world. It represents the highest level of mechanical equipment thermal processing manufacturing technology and is the first manufacturing at home and abroad.
In recent years, GJZZ has leveraged its advantages in extreme manufacturing technology throughout the entire industry chain, breaking through multiple key core technologies on the basis of complete independent innovation, and forming a systematic and complete forging main pipeline manufacturing technology, ensuring the smooth construction of China’s third-generation nuclear power demonstration projects represented by “Guohe No.1” and “Hualong No.1” and subsequent nuclear power projects.
