Lined plate heat exchanger for corrosion protection
Thread Content
My materials are too corrosive; the alloys commonly used are not suitable. I was wondering if it’s possible to line metal-based heat exchange plates with glass lining Then make a corrosion-resistant heat exchanger.
Your request is quite novel; it seems rather difficult to fulfill.
A tantalum-plated metal plate should work; it should be able to solve your problem
We have also provided metal sheets coated with polytetrafluoroethylene, for use in corrosive industrial and mining environments
How much of an impact does a plastic coating have on heat transfer? What’s the thickness? Is it resistant to media containing particles?
I’ve had similar thoughts too. Previously, the heat exchange tubes were made of carbon steel, which kept rusting; using stainless steel would result in too high costs, and the customers would not accept that. Later, I thought of enamel and glass lining; the final solution was to use a composite material of carbon steel and stainless steel.

Plastic coating has little impact on heat transfer; it’s similar to non-stick pans used in our homes. However, it doesn’t work well with abrasive substances – just as with non-stick pans, we can only use wooden or plastic spatulas.
The material contains no solid particles and is filtered. You can contact me on QQ 1804426805
There are glass-lined tubular and plate heat exchangers
I’m not sure what you mean by that; if the structure is too complex, it’s not recommended to use enamel coating. All enamel-coated structures should be as simple and continuous as possible. There should be no sudden changes; those points are the structural stress points, the areas most prone to damage
