Boasting systematized production facilities and superior technology, Doosan Heavy Industries & Construction provides extra-large casting and forging products for power plants, marine vessels, iron and steel making, mold and tool steel, and other industrial facilities all around the world.
Doosan’s portfolio includes large castings and forgings for major nuclear energy components, such as nuclear reactors and steam generators, as well as castings and forgings for gas turbines, steam turbines and generators for nuclear, thermal and hydro power plants. Notably, Doosan has acquired superior technology for casting/forgings like Shell, Rotor, Casing, and Head, many of which have been supplied to major plants globally and have had their quality verified.
A nuclear reactor and steam generator, core parts of a nuclear power plant, often have problems with welding and assembly with pressurized containers. Doosan’s Integrated Head with Nozzle ensures longer service life and safety by forging the nozzle and flange. Customers recognize the excellence of our technology for the Integrated Head with Nozzle for steam generators and nuclear reactors (the Korean standard APR1400 as well as the WEC standard AP1000).A nuclear reactor and steam generator, core parts of a nuclear power plant, often have problems with welding and assembly with pressurized containers.

The nuclear shell inside the pressurized container of a nuclear reactor is used in an atmosphere of continuous and extreme heat and high pressure from high-speed neutrons, thus requiring such properties as high solidity and high resistance to fractures. Doosan Heavy Industries and Construction is capable of manufacturing Upper, Inter, and Lower Shells for steam generators and reactors.
A core part of nuclear power and thermal power plants, a rotor shaft is a large, high-speed revolving shaft. It requires the strictest manufacturing procedure and quality management of all large castings/forgings. Its production requires extra pure molten steel from select material, formation technology, special forging and thermal processing technology, and advanced non-destructive evaluation technology.
A turbine casing is one of the core components of the turbines used at nuclear, thermal and gas turbine power plants. It comprises many parts including the diaphragm assembled inside it. It is structured to maximize the kinetic energy of steam so that energy can be efficiently converted to mechanical energy to rotate the rotor. Doosan Heavy Industries & Construction offers outstanding technology and facilities to manufacture products that fulfill the product requirements including material properties and strict non-destructive evaluation criteria. Its products have been supplied to many power plants worldwide, generating outstanding results.
A runner is a core component of a hydro power plant. Doosan Heavy Industries & Construction boasts the largest stainless steel runner production capacity in the world, and supplies integrated runners, crowns, bands, and blades, etc. to hydro power plants all around the world.
