These tubes come in various sizes, types, dimensions, and thicknesses, and we also offer customisation to meet our clients’ needs at competitive prices.

The main function of an air preheater is to recover heat from boiler flue gas, thus increasing the boiler’s thermal efficiency by reducing the heat lost in the flue gas. Air Preheaters (APH) are shell and tube-type heat exchangers used to preheat the air going into boilers or furnaces/kilns for fuel combustion. Their primary goal is to extract waste heat from the flue gases leaving the boiler.

Our APH ERW Tubes are produced as hot-rolled or cold-drawn tubes with welded and seamless ends. The size and grade of these tubes depend on the boiler’s design, which is influenced by factors such as fuel type, temperatures, pressures, and steam requirements.

Our Air Pre Heater ERW Tubes find extensive use in manufacturing and maintaining boilers in power plants and industries like Chemical, Sugar, Power Plant, Steel, Cooling Tower, Super Heater, Paper, Air Heaters, Heat Exchanger, and more.

Quality is our top priority, and we conduct rigorous testing to ensure our products meet or exceed industry standards. Our tests include PMI tests, raw material tests, intergranular corrosion tests, pitting resistance tests, flaring/flattening tests, third-party inspection tests, and other quality checks.
