Studies on aluminium diffusion treated steel for heat exchanger tubes

Abstract

Aluminium diffusion treated steel by pack process using ferroaluminium was studied for its heat exchanger tube applications properties. The laboratory and inplant corrosion studies reveal that the diffusion treated low carbon steel is extremely resistant to hot corrosion due to sulphurous gases encountered in heat exchanger tubes of sulphuric acid plants at the operating temperatures. The diffusion treated tubes have shown adequate physical properties for heat exchanger tube bundle fabrication.
