Tube Sheet Forgings


Nuclear power tube sheets are mainly applied in equipment such as steam generators in nuclear power plants, featuring product advantages including excellent sealing performance, high strength, and strong corrosion resistance. They are also used in key equipment of nuclear power plants, like steam generators and reactor pressure vessels.
In steam generators, tube sheets serve to support and fix heat transfer tubes, ensuring the heat transfer process proceeds efficiently and stably while preventing the mixing of shell-side coolant and tube-side steam. In reactor pressure vessels, tube sheets also perform similar supporting, fixing, and sealing functions to ensure the safe operation of the equipment. They are crucial components in nuclear power plants that guarantee energy conversion and safety protection.
