Manufacture of steam generators, except central heating hot water boilers

NACE v2.0 Code: C25.3

About manufacture of steam generators, except central heating hot water boilers

NACE code 25.3 covers the manufacture of steam generators, excluding central heating hot water boilers. This industry plays a crucial role in providing essential equipment for power generation, industrial processes, and heating systems across various sectors. As a key component of the broader machinery and equipment manufacturing industry, the steam generator market is closely tied to the performance and demands of the energy, manufacturing, and construction industries.

Production process

The production of steam generators typically involves a multi-step process. This includes the fabrication of pressure vessels, the installation of heating elements, the assembly of control systems, and the integration of auxiliary components such as valves and piping. Manufacturers utilize specialized metalworking techniques, welding, and precision engineering to ensure the safety, efficiency, and reliability of the final products.

Production inputs

The manufacture of steam generators requires a range of raw materials, including steel, copper, and various alloys. Manufacturers also rely on advanced machinery and equipment, such as metal-cutting tools, welding machines, and testing apparatus. Additionally, the industry depends on a skilled workforce capable of operating specialized production equipment and adhering to strict safety and quality standards.

Production outputs

The primary output of this industry is steam generators, which are used in a variety of applications, including power plants, industrial facilities, and large-scale heating systems. The steam generated by these units can be used for electricity generation, process heating, or space heating. Other NACE codes that may consume the output of the steam generator industry include 35.1 Electric power generation, transmission and distribution, 23.9 Manufacture of other non-metallic mineral products, and 28.2 Manufacture of other general-purpose machinery.
