what kind of material we can use to manufacture a heat exchanger.e.g steel ,copper etc.
It depends upon the application with reference to type of media,temperature,effect of flow,pressure and many. Materials for tubes,tubesheet,shell,baffles and other parts are different. for shell and tube heat exchanger. For plate heat exchanger ,plate MOC is of prime-importance. Common heat-exchanger materials are : carbon steel stainless[ss304,ss316,monel,inconnel,h... steel]- for special application. For refrigeration services copper tubes are common and shell material is carbon steel. It would be fine if you have given the application details. *Once the exchanger type is determined, the construction materials can be chosen. -Material selection hinges on finding the best mix of economy and performance. Original equipment cost must be balanced against the equipment's life expectancy and its maintenance costs. Because corrosion is an everyday fact in the finishing industry, mild steel exchangers should be avoided, except for short-run processes. Instead, in most systems where corrosiveness of the atmosphere and solutions is low, type 316 stainless steel provides additional protection at a modest price. In more corrosive applications, material selection becomes even more important. Some selections are easy: Stainless steel for caustics Titanium for nickel plating Columbian/niobium for fluoride-bearing chromium plating solutions.
normally copper tube for shell and tube and stst.316 for plate heat exchangers.
