Alloy Steel Pipe ASTM A335 P9 with 11Cr Studded Fin tube for reactor feed heater, Recovery Furnace application
Alloy Steel Pipe ASTM A335 P9 with 11Cr Studded Fin Tube is a high-performance piping product designed for demanding high-temperature and high-pressure applications. The combination of ASTM A335 P9 alloy steel and 11Cr studded fins provides superior strength, excellent corrosion resistance, and enhanced heat transfer capabilities.
Studded tubes are used in fire furnaces to enhance heat transfer efficiency and improve the overall performance of the furnace. The studs on the tubes create turbulence in the flue gas flow, which helps in increasing heat transfer rates. This results in improved thermal efficiency and reduced fuel consumption.
