Stainless Steel Condenser Tubes

Stainless steel condenser tubes have been widely used due to their excellent corrosion resistance and ability to ensure long-term continuous and full-load operation of generator sets, and become the largest alternative to copper alloy condenser tubes. The main problems of the current condenser are the leakage of the condenser tube and the short service life.

Stainless Steel Condenser Tube

The stainless steel condenser tubes are a kind of heat exchanger tube, which is generally made of seamless tube stainless. The main function is to realize the heat exchange of steam or other media in the condensation process.

In the complete set of steam turbine equipment in the boiler power generation industry, the condenser is the equipment that condenses the exhaust steam of the steam turbine into the water and returns it to the boiler to start the next cycle.

The stainless steel condenser tubes are one of the key components of the condenser, which is responsible for the entire heat conversion process.

Usually, freshwater or seawater passes through the tube, and high temperature and high-pressure steam are outside the tube. In supercritical and ultra-supercritical boiler-generator sets, new requirements are put forward for the material and quality of the heat exchange condensing tube used in the condenser, especially the water corrosion resistance and impact corrosion resistance of the material, as well as the mechanical properties, process properties, and thermal properties. The exchange rate has put forward higher requirements.

Stainless Steel Condenser Tubes Specification:

Stainless steel condenser tube is designed for heating, cooling, or reheating fluids and gases. Precision pipelines are often used in thermal power plants, nuclear power plants, and chemical plants. Stainless steel condenser tubes have many standard sizes and grades, such as 304 / 304L and 316 / 316L, etc.

Why more people choose stainless steel condenser pipes?

In recent years, stainless steel condenser tubes have been widely used due to their excellent corrosion resistance and ability to ensure long-term continuous and full-load operation of generator sets, and become the largest alternative to copper alloy condenser tubes. The main problems of the current condenser are the leakage of the condenser tube and the short service life. One of the main reasons is the material problem of the cooling tube system.

Under normal circumstances, the condenser tube plate is made of ordinary low carbon steel, and there are certain differences in the physical, mechanical, and chemical properties of the copper alloy condenser tube. These differences may have some impact on the service life of the tube during the operation of the unit. Negative Effects. The choice of copper alloy tube sheet will greatly increase the material cost of equipment manufacturing. Stainless steel condenser tubes greatly reduce these differences and increase the normal operation period of the unit, which is very important for generating units, especially large-scale units.
