Compared with conventional engineering forgings, what are the special technical requirements for nuclear project forgings?

In the complex engineering field, nuclear project forgings play a vital role. Compared with conventional engineering forgings, nuclear project forgings face more stringent working environments and higher performance requirements. This is not only reflected in their design and manufacturing process, but also in a series of special technical requirements that they must meet.

Nuclear project forgings need to withstand extremely high pressure and temperature. In nuclear power plants, key components such as reactors, steam generators, and main pipelines require the use of high-strength forgings to ensure structural integrity and safety. These forgings must maintain stable mechanical properties under conditions, such as high strength, high toughness, and high heat resistance to withstand the huge heat and pressure generated by the reactor.

Nuclear engineering project forgings must have good radiation resistance. In the nuclear reactor environment, the presence of radioactive materials places extremely high demands on the performance of materials. Forging materials must be able to withstand the effects of long-term radiation without performance degradation or failure. This requires the material to have radiation resistance to ensure the long-term safe operation of nuclear power plants.

In addition, nuclear engineering project forgings also need to meet strict process requirements during the manufacturing process. During the forging process, parameters such as temperature, pressure and deformation must be strictly controlled to ensure that the internal structure and performance of the forgings are in the state. At the same time, the surface quality of the forgings must also be strictly guaranteed to avoid problems such as cracks and corrosion during subsequent use.

Nuclear engineering project forgings also need to undergo strict testing and certification. After manufacturing, the forgings need to undergo a series of mechanical property tests, non-destructive testing and irradiation tests to ensure that they meet the design requirements and safety standards. These testing and certification processes are not only a guarantee of the quality of forgings, but also a guarantee of the safe operation of nuclear power plants.

In order to meet these special technical requirements, the production of nuclear engineering project forgings usually requires the use of advanced manufacturing technology and equipment. For example, the use of precision forging processes and heat treatment technologies can optimize the internal structure and performance of forgings; the use of advanced non-destructive testing technologies can conduct comprehensive quality inspection and evaluation of forgings.
