What corrosion affects the inside and outside of the tube furnace tube

What corrosion influences the inside and outside of the tube of the type furnace

The working principle of tubular furnace is: fuel is burned in the radiation chamber of tubular furnace (very few in a separate combustion chamber), and the heat released is mainly transferred to the furnace tube through radiation heat transfer and convection heat transfer, and then through conduction heat transfer and convection heat transfer to be heated medium, which is the working principle of tubular furnace.

What corrosion influences the inside and outside of the tube of a tubular furnace?

1) Corrosion of the medium inside the furnace: sulfur corrosion, naphthenic acid corrosion, hydrogen damage, hydrogen and hydrogen sulfide corrosion, polysulfuric acid corrosion, etc.;

2) External medium corrosion of furnace tube: vanadium corrosion at high temperature and dew and spot corrosion at low temperature.
