Alloy Steel Pipe ASTM A335 P9  with 11Cr Studded Fin tube for reactor feed heater, Recovery Furnace application

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.
