An Air Pre Heater (APH) tube is an essential component in air preheaters, which are heat exchangers used in industrial applications such as boilers, furnaces, and kilns. The primary function of an air preheater is to preheat the combustion air using waste heat from flue gases exiting the boiler or furnace. This preheating process enhances the system’s thermal efficiency by reducing the amount of usable heat lost in the flue gas.
APH Tubes are crucial in transferring heat from the hot flue gases to the incoming cold air. These tubes are typically made from high-quality materials using advanced manufacturing techniques to ensure durability and optimal performance. They come in various shapes, sizes, and specifications to meet the diverse requirements of different industrial applications.
The primary function of an air preheater (APH) is to capture and utilize the waste heat present in the flue gases as they exit a boiler. The air preheater tube is a vital component in this process, ensuring the efficient operation of the APH system. To guarantee the performance and longevity of the APH system, these tubes must meet stringent requirements, including elongation, hardness, yield strength, and tensile strength.
APH Tubes are available in welded or seamless forms and can be hot-rolled or cold-drawn. The choice of APH ERW tubes depends on the boiler’s design, which is influenced by factors such as fuel type, operating temperatures, pressures, and steam volume requirements.
Air Pre Heater ERW Tubes are widely used across various industries, including power plants and process industries such as chemicals, sugar, power generation, steel manufacturing, cooling towers, superheaters, paper production, and air heating systems. Their reliability and efficiency are paramount in these applications.
Our top priority is ensuring our products meet and exceed industry standards for quality. Our APH Tubes undergo rigorous testing, including third-party inspections, PMI testing, raw material analysis, intergranular corrosion tests, pitting resistance assessments, and mechanical tests like flaring and flattening. This commitment to quality ensures that our products are reliable and perform optimally.
