In the power industry, stainless steel pipes are widely used due to their reliable corrosion resistance, high-temperature resistance, and mechanical properties. These pipelines are used to transport various fluid media, such as cooling water, steam, chemical reagents, etc., to meet the operational needs of power equipment.
Thermal power generation is the use of coal combustion heat energy to heat water, so that water into high-pressure steam, and then by the steam to drive a generator and then generate electricity as a way of power generation. The thermal power station is mainly composed of a power generation boiler, steam turbine, and generator. The steam and water pipes in power generation boilers include reheating pipes, superthermal pipes, water wall pipes, economizer pipes, air preheating pipes, heat conduction pipes, drop pipes, and various combination box pipes.
Because the use of the above pipelines is under high temperature and high-pressure conditions for a long time, the pipelines will undergo oxidation and corrosion under the action of high-temperature flue gas and water vapor, so the steel pipes are required to have high-lasting strength, high oxidation and corrosion resistance and good structural stability. In order to meet the above requirements, stainless steel pipes are widely used in thermal power boilers.
The main applications of stainless steel pipes in the power industry include:
1. Conveying cooling water: used in the cooling system of generator sets, transformers, and other equipment.
2. Conveying steam: steam systems for steam turbines, boilers, and other thermal equipment.
3. Conveying chemical reagents: used in chemical water treatment, wastewater treatment, and other systems.
Nuclear grade pipes in nuclear power plants: used for transporting radioactive media and high temperature and high-pressure water.
Special requirements for stainless steel electrical pipes in the power industry include:
1. Corrosion resistance: A stainlesssteel electrical pipe can resist the erosion of various corrosive media to ensure the long-term stable operation of the pipeline.
2. High-temperature resistance: can maintain good mechanical properties and stability in high-temperature environments.
3. Sealing: Ensure that there is no leakage at the pipe connection and prevent media leakage from causing security risks.
4. Cleanliness: For some special applications, such as nuclear-grade piping in nuclear power plants, an extremely high degree of cleanliness is required inside the piping.
