Plate-and-shell heat exchangers are widely used due to their resistance to high temperatures and pressures, as well as their diverse combination of processes, wide range of applications, and adaptability to various operating conditions. A plate-and-shell heat exchanger is mainly composed of a plate bundle and a shell, so what is the actual production and assembly process for it? First is the procurement of raw materials, as well as the inspection to ensure that the coiled tubes are of qualified quality. Step 2: Weld the shell side and pipe flanges. Step three: Inspect the plate after it leaves the warehouse, and weld the inner hole and outer circle. Step four: assemble and install the protective plates. Step five, assembly. Step six: Cylinder welding and cover installation. Step 7: Flange alignment of the plate process. Step eight: Surface treatment. Step 9: The inspection and testing are successful. Step ten: Code-marking and packaging. By following these ten steps, a plate-and-shell heat exchanger can be manufactured and assembled. It has high heat transfer efficiency, operates in pure counterflow, features high turbulence inside the plate bundle, and is resistant to scaling. The overall structure is compact, occupying a small area.
