Issues with baffle plates and tube materials in shell-and-tube heat exchangers
Thread Content
If the tube side of the heat exchanger is made of 316L, and the shell side is made of carbon steel, should the baffle plates also be made of carbon steel? Rest!
The key is what the properties of the medium in the shell side are like
The shell side is made of carbon steel; of course, the baffle plates can also be made of carbon steel
The shell side consists of steam and condensate water. What’s the point of worrying about that again?
In that case, there’s no problem; using carbon steel will do
The baffle made of carbon steel comes into contact with the heat exchange tubes made of stainless steel, and the medium is condensate water – is there a risk of galvanic corrosion?
Generally, what foreigners do is use the same material for the heat exchange tube
It’s fine to use carbon steel; the housing itself is made of carbon steel
Heat exchange tubes made of stainless steel, when used with baffle plates made of carbon steel, may suffer from contamination by stainless steel, leading to corrosion
