Stainless Clad Plates Versus Other Metal Plates In Anti-corrosion Vessel Fabrication

Jun. 19, 2018


1.The comparison with pure stainless steel plate


Costs comparisons


When it comes to the same specifications, the cost of stainless steel clad plate is lower than that of pure stainless steel plate by 40-60%.


Corrosion resistance comparisons


Stainless steel clad plate is able to serve the purpose of corrosion resistance like the pure stainless steel plate.


Safety comparisons


There is a risk of explosion caused by intergranular corrosion in pressure vessels made out of pure stainless steel, but this will not happen to pressure vessels made out of stainless steel clad plate because it is backed by the strong carbon steel.




2.The comparison with inner lining stainless steel


Costs comparisons


When inner lining stainless steel is used, Only the thickness of the base plate will be calculated. So the cost is somewhat similar to that of the stainless steel clad plate.


Corrosion resistance comparisons


Inner lining stainless steel can meet its corrosion resistance under certain conditions.


Safety comparisons


The stainless steel and the base plate are only fit, there is still some gap. Once a point is eroded, the entire interlayer will be eroded by corrosive medium. And there might be a great risk accompanied.



3.The comparison with carbon steel plate


Costs comparisons


The cost of carbon steel with anti-corrosive coating(epoxy resin composite coatings,ceramic filled coating or phenolic epoxy coating.etc)accounts for 30-40% of the pure stainless steel which is relatively lower than that of stainless steel clad plate.


Corrosion resistance comparisons


Carbon steel with anti-corrosive coating can meet its corrosion resistance under certain conditions.


Safety comparisons


The coating is quite easy to shed off during the application. Once this happens,the carbon steel will be soon eroded. So the service life is short and the maintenance cost is high. And there might be a great risk accompanied.
