Fixed tube-sheet type heat exchanger benefits are secure and compact structure, and low cost of manufacturing. The both end of tube sheets has the fixed tube-sheet heat exchanger are connected and fixed with the shell by means of the welding method. the diameter are same of shell , tubular heat exchangers is also available as biggest and the tube bundle for heat transfer can be arranged into single pass, two pass or multi pass as per requirements. So fixed tube-sheet type heat exchanger is widely applied in the engineering. The disadvantages of the fixed tube-sheet type heat exchanger are that the shell pass cannot be cleaned with the mechanical method and the maintenance is difficult. The fixed tube-sheet heat exchanger is applicable to the services where the temperature difference between the shell and the tube is small, the temperature difference is slightly great but the pressure of shell pass is not high with the media in the shell pass not easy to scale, or the shell pass can be cleaned with the chemical method after the scaling is formed. The Tube and shell heat is good due to the temperature difference, an expansion joint can be mounted inside the shell to decrease the thermal stress caused by the temperature difference. Straight tubes are expanded on two opposite tube sheets, which are welded directly to the shell. Fixed tube Sheet Heat Exchanger Advantages 1. It has a Less cost than removable bundle heat exchangers. 2. Provides maximum heat transfer surface per given shell and tube size. 3. Provides multi-tube-pass arrangements. The Fixed Tube sheet heat exchangers are developed by the process of welding method. It has connected with both of ends in fixed tube sheet heat exchanger. It is a very low cost manufacturing with simple and different structure. It has an same diameter of shell level of sizes and biggest numbers of tubular and it can be bundle with arrangement ,it requires one pass, two pass , multi-pass tubular methods. So fixed tube-sheet type heat exchanger is widely applied in the engineering. The disadvantages of the fixed tube-sheet type heat exchanger are that the shell pass cannot be cleaned with the mechanical method and the maintenance is difficult. The fixed tube-sheet heat exchanger is applicable to the services where the temperature difference between the shell and the tube is small, the temperature difference is slightly great but the pressure of shell pass is not high with the media in the shell pass not easy to scale, or the shell pass can be cleaned with the chemical method after the scaling is formed.We have different models to emuculate the product structure, Our product models have to expansion with shell and tube . When the temperature difference between the shell and the tube is great, an expansion joint can be mounted inside the shell to decrease the thermal stress caused by the temperature difference. Fixed tube Sheet Heat Exchanger Applications It has an widespread application, except in case that require the removal of the tube bundle for maintenance. The Fixed tube is specifically allowed for vacuum operations on the outer circuit or when gaskets are not desired on this circuit. In that its particular, it is used as a coolant for oil, and using steam outside the tube are transformers or or small instant diesel or heaterlubrication system.One of the most common applications is the cooling of Hydraulic Fluid and oil in engines, transmissions and hydraulic power packs.
