Can the heat exchange tubes and tube sheets be made of different materials?

Can the heat exchange tubes and tube sheets be made of different materials? For example, in the tube-and-sheet carbon steel type, the heat exchange tubes are 304
Of course. As in the example you gave, welding 304 material on the welded end of the tube sheet ensures a proper weld while also helping to save on the high costs associated with stainless steel tube sheets
Are there any regulatory requirements or design criteria?
Of course! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
Of course, the tube sheet can be made of a composite plate.
Yes, but the welding material must be matched.
Sure! ! ! ! ! ! ! ! ! ! ! !
Different materials can be used, and cladding can be applied to the side of the tube sheet that is exposed to corrosion
No problem; the tube sheet is made of carbon steel or stainless steel, while the heat exchange tubes are made of copper
Both composite tube sheets and cladding are acceptable
