What are Air Preheater Tubes (APH Tubes)?

APH tubes also known as heat resistant alloy tubes, created for boiler air preheater applications, optimize extreme temperature and pressure. Heat Resistant alloy tubes recover heat from the combustion exhaust, given air is preheated before entering the combustion process. Our air preheater tubes boast tensile strength, corrosion resistance, and oxidation resistance. These tubes are more typically used in a power plant, petrochemical, or other heat exchanger applications.
